Description

Linear organopolysiloxane having different functional groups at both ends, and method for producing the same

The present invention relates to a linear organopolysiloxane having different functional groups at both ends and a method for producing the same. Moreover, this invention provides the polysiloxane compound which has a terminal amino group and another terminal functional group, and its manufacturing method.

Conventionally, organopolysiloxanes containing organic functional groups have been widely used as resin modifiers in the fields of paints, molding materials, medical materials, various coating materials, etc., and have heat resistance, weather resistance, mold release properties for organic resins. Properties such as heat resistance, molding processability and thermal shock resistance.

As an organopolysiloxane containing such an organic functional group, Patent Document 1 describes a compound having functional groups at both ends of dimethylpolysiloxane. Patent Document 2 proposes methylpolysiloxane having a functional group in the side chain. However, all of these organopolysiloxanes have only one type of functional group.

An organopolysiloxane having one type of functional group at both ends and / or side chains has characteristics according to the functional group, and it is not possible to give organopolysiloxane various characteristics possessed by a plurality of functional groups. Have difficulty. Also, since the difference in reactivity depending on the type of functional group cannot be used with the same functional group alone, it is difficult to precisely control the reaction such as using different crosslinking methods or using polymerization and crosslinking separately. is there.

Patent Document 3 describes organopolysiloxanes having different types of functional groups in one molecule. Patent Document 3 describes that a heterofunctional organopolysiloxane having a different functional group in the side chain is produced by reacting a different allyl compound with the side chain type hydrogen polysiloxane.

However, the organopolysiloxane described in Patent Document 3 has a functional group in the side chain having a large steric hindrance, and the introduced functional group exists as an average, and the structure is not clear. Control is not enough.

Patent Document 4 describes an organosiloxane having a hydrophilic group and a polymerizable group at its terminal, which is useful as a medical device material. Patent Document 4 discloses a heterogeneous terminal organosiloxane having a first functional group and a hydrogensilyl group after purification by introducing a first functional group by reacting a first allyl compound with a both-end type hydrogensiloxane. And further reacting the remaining hydrogensilyl group with a second allyl compound to produce an organosiloxane having different functional groups at both ends.

However, the production method described in Patent Document 4 requires distillation or column purification in the step of obtaining an organosiloxane having a first functional group and a hydrogensilyl group. In principle, only low molecular weight organosiloxanes can be produced by this method. Therefore, in the compound obtained by the manufacturing method described in Patent Document 4, the content of siloxane is low. Even if the siloxane is used as a raw material, the characteristics of the siloxane cannot be sufficiently imparted to the polymer or the like.

Organopolysiloxane compounds having different functional groups at their ends are useful in fields such as resin modifiers and medical device materials, but there is currently no material with a clear structure and sufficient siloxane properties. It is.

Various terminal amino-functional silicone compounds are known, and these are both terminal amino-functional silicone compounds having amino groups at both ends and one-terminal amino-functional silicone compounds having functional groups only at one end. (Patent Documents 5 and 6). A silicone compound having an amino group at one end and another terminal functional group at the other end can react with two different substrates depending on the reactivity of the two functional groups in a single compound. Although it is considered useful as a resin modifier, it has not been studied at present.

For example, [1] A method for producing a silicone having a terminal amino group and other terminal functional groups by reacting both terminal amino functional silicones and both terminal carbinol functional silicones in the presence of trifluoromethanesulfonic acid is considered. It is done.

[2] After reacting a vinyl compound and a large excess of both-end hydrogen silicones in the presence of a platinum catalyst, purification is performed by distillation or the like, and this is reacted with allylamine to produce terminal amino groups and other terminal functional groups. A method for producing a silicone having the following is conceivable.

However, in the method of [1], it is difficult to selectively obtain those having different functional groups in one molecule, and the isolation is practical because of the wide distribution of the structure of the product. is not. In the method of [2] above, in order to leave hydrogen at one end, a large excess of hydrogenpolysiloxane at both ends relative to the vinyl compound is required, subsequent purification is difficult, and allylamine is a catalyst poison. Therefore, a large amount of platinum catalyst is required, which is not realistic. Furthermore, since dehydrogenation of allylamine and —SiH occurs as a side reaction, the purity of the silicone having a terminal amino group and other terminal functional groups is not high.

Since it is difficult to synthesize a silicone compound having a terminal amino group and other terminal functional groups with high purity by the above method, a silicone compound having a terminal amino group with high purity and other terminal functional groups, and its production There is a need for a method.

Accordingly, an object of the present invention is to provide a hetero-functional organopolysiloxane compound having different functional groups at both ends of the polysiloxane and having a sufficient siloxane content, and a method for producing the same. Moreover, this invention provides the polysiloxane compound which has a terminal amino group and another terminal functional group, and its manufacturing method.

As a result of intensive studies to solve the above problems, the present inventor has made a step of reacting a cyclic siloxane or disiloxane having a first organic functional group with an organometallic compound, a metal silicate compound obtained by the step and a second silicate compound.

Furthermore, by the method of the present invention for obtaining a silicone having a terminal amino group represented by the above formula (1) and other terminal functional groups from the compound (4), the silicone represented by the above formula (1) is very high. Can be produced in purity. In the reaction of hydrogenpolysiloxane conventionally known and amines, dehydrogenation reaction due to amino groups often occurs. Surprisingly, in the production method of the present invention, the dehydrogenation reaction due to generated amino groups is negligible. Highly pure silicones having terminal amino groups and other terminal functional groups can be obtained. Even if an acid is allowed to act to accelerate the desilylation reaction, the siloxane chain is hardly broken and only the silyl group is selectively desilylated. Therefore, the target compound represented by the above general formula (1) Can be produced with high purity. Furthermore, it has also been found that desilylation proceeds better with an optimal combination of a specific alcohol and a specific acid catalyst.
A silicone compound having an amino group at one end and another terminal functional group at the other end reacts with two different substrates depending on the reactivity of the two functional groups in a single compound. Can do. For example, the other terminal functional group can be introduced into the resin by reacting the compound with a resin having a group that reacts with an amino group. In a system in which a resin having a group that reacts with an amino group and a resin having a group that reacts with the other functional group are mixed, each resin can be selectively modified. Thus, according to the present invention, a silicone compound having an amino group at one end and another terminal functional group at the other end is useful as a resin modifier.

The present invention further provides a method for producing a silicone compound represented by the above formula (I).
The production method (production method A) of the present invention comprises a compound represented by the following formula (8):

(R ¹ , Q ¹ , m and A are as described above, and Mt is an alkali metal atom, for example, lithium)
A halogenated silyl compound represented by the following formula (7):

(R ¹ , Q ² , b and B are as described above, and X ¹ is a halogen atom, for example, a chlorine atom, a fluorine atom or a bromine atom, preferably a chlorine atom)
And a step of obtaining a silicone compound represented by the above formula (I).

The above reaction can be performed according to a conventionally known method. The addition amount of the halogenated silyl compound represented by the above formula (7) is preferably an amount ratio of 0.8 to 2.0 mol, more preferably, 1 mol of the compound represented by the above formula (8). An amount ratio of 0.9 to 1.5 mol is preferable, and an amount ratio of 1.0 to 1.2 mol is more preferable.

Furthermore, the production method A of the present invention is a cyclic siloxane represented by the following formula (iii)

(Y is an integer of 3 to 10, R ¹ and Q ¹ are as described above, and A ¹ is a functional group or atom that is non-reactive with the organometallic compound.)
Or
Disiloxane represented by the following formula (iv):

(R ¹ and Q ¹ are as described above, and A ¹ is a functional group or atom that is non-reactive with the organometallic compound.)
Reaction with an organometallic compound results in the following formula (v)

(R ¹ , Q ¹ , and Mt are as described above, and A ¹ is a functional group or atom that is non-reactive with the organometallic compound.)
Next, the metal silicate compound represented by the above formula (v) is reacted with a cyclic siloxane such as hexamethylcyclotrisiloxane to obtain the following formula (8 ′).

(R ¹ , Q ¹ , m, and Mt are as described above, and A ¹ is a functional group or atom that is non-reactive with the organometallic compound)
The process of obtaining the siloxane represented by these is included.
In the above step, the cyclic siloxane to be reacted with the metal silicate compound represented by the above formula (v) is, for example, an alkylcyclopolysiloxane such as hexamethylcyclotrisiloxane, and the cyclic siloxane represented by the above formula (iii). It is a compound different from siloxane.

In this step, the compound represented by the above formula (iii) or the above formula (iv) is reacted with an organometallic compound. Therefore, in formulas (iii) and (iv), A is a functional group that is non-reactive with the organometallic compound. At this time, A may be inactive (non-reactive with the organometallic compound) during the reaction with the organometallic compound. Accordingly, a functional group having reactivity for inactivation may be protected with a conventionally known protecting group. For example, examples of the protecting group for hydroxyl group and amino group include silyl group and benzyl group. These protecting groups may be removed by a conventionally known method after the reaction with the organometallic compound. For example, the silyl group can be removed in the presence of water or alcohol. The reaction can be accelerated in the presence of acid or base.

The compound represented by the above formula (iii) or (iv) can be produced according to a conventionally known method. For example, it can be obtained by a hydrosilylation reaction between 2,4,6,8-tetramethylcyclotetrasiloxane or 1,3-tetramethyldisiloxane and an organic compound having an unsaturated bond. The reaction may be carried out under a conventionally known catalyst. For example, a noble metal catalyst, particularly a platinum catalyst derived from chloroplatinic acid is preferred, and a karsted catalyst is more preferred. The reaction may be performed according to a conventionally known method.

The organometallic compound is a polymerization initiator and may be any one that is usually used for ring-opening polymerization of cyclic siloxane. For example, an organic compound having an alkali metal atom, particularly an organic lithium compound. The organolithium compound is a compound having a carbon-lithium bond. These may be any conventionally known compounds. Examples of the organic lithium compound include methyl lithium, ethyl lithium, butyl lithium, phenyl lithium, benzyl lithium and the like. In particular, an organolithium compound diluted in a hydrocarbon-based compound such as hexane or cyclohexane is preferable, and a hexane solution of n-butyllithium is more preferable in view of handleability and availability. An organomagnesium compound can also be used as the organometallic compound. The organomagnesium compound is a compound having a carbon-magnesium bond and a magnesium-halogen bond.

The amount of the organometallic compound may be an amount ratio of 1 mol with respect to 1 mol of the siloxane represented by the above formula (iii) or the above formula (iv). When the amount of the organometallic compound is larger than the above, a side reaction of the organometallic compound occurs, which is not preferable. Moreover, when less than the said lower limit, since there exists a possibility that the siloxane shown by the said Formula (iii) or the said Formula (iv) may remain | survive, it is not preferable.

The above reaction can be carried out according to a conventionally known method. For example, the compound represented by the above formula (iii) or (iv) is reacted by adding an organometallic compound of 1 molar equivalent or less, and subsequently hexamethylcyclotrisiloxane is added and reacted. For example, when 2,4,6,8-tetramethyl-2,4,6,8-tetra (N, N-dimethylaminopropyl) cyclotetrasiloxane is reacted with BuLi, BuMe (C ₃ H ₆ NMe ₂ ) SiOLi Occurs. Using this as an initiator, hexamethylcyclotrisiloxane is ring-opened and reacted to obtain a compound represented by the above formula (8 ′). Further, a halogenated silyl compound is added and reacted to obtain a silicone compound represented by the above formula (I). The addition of the organometallic compound, hexamethylcyclotrisiloxane, and halogenated silyl compound is typically performed at a temperature of about 0 ° C to about 40 ° C. Although reaction temperature is not specifically limited, The temperature of the grade which does not exceed the boiling point of the solvent to be used is preferable. The end point of the reaction of hexamethylcyclotrisiloxane is confirmed by the disappearance of the peak in the GC measurement, for example, after the completion of the dropping and after aging under heating, the presence or absence of the raw material hexamethylcyclotrisiloxane. By confirming the reaction end point by GC measurement, since the hexamethylcyclotrisiloxane does not remain in the product, a higher purity silicone compound can be obtained.

Any of the above reactions may be performed in a solvent. The solvent is not particularly limited. For example, hydrocarbon solvents such as hexane and heptane, aromatic solvents such as toluene, ether solvents such as tetrahydrofuran, ketone solvents such as methyl ethyl ketone and N, N-dimethylformamide. An ester solvent such as ethyl acetate can be preferably used.

After completion of the reaction, it may be purified according to a conventionally known method. For example, the product can be isolated by washing the organic layer with water and then removing the solvent. Further, vacuum distillation or activated carbon treatment may be used.

CH ₂ = CHCH ₂ N (SiR ² ₃ ) ₂ (6)
(Wherein R ² is as described above.)
Hereinafter, the production method B will be described in more detail.

Bi) Production of silicone having terminal amino group and other terminal functional group In the general formula (1) of the present invention, m is particularly preferably an integer of 1 to 6, and more preferably an integer of 2 to 5. It is. If m is larger than the upper limit, it may be difficult to purify by distillation. R ¹ is independently of each other preferably a substituted or unsubstituted hydrocarbon group having 1 to 6 carbon atoms, and examples thereof include alkyl groups such as a methyl group, an ethyl group, a propyl group, an isopropyl group, a butyl group, and a hexyl group. Aryl groups such as phenyl groups, and those obtained by substituting some or all of the hydrogen atoms of these groups with fluorine, such as trifluoropropyl groups.

For example, the carbon-carbon bond of the C ₁ -C ₄₈ alkyl group may be interrupted with one or more oxygen atoms to form a mono or polyether. The C ₁ -C ₄₈ alkyl group is preferably a C ₁ -C ₂₄ alkyl group. Examples of the substituent include halogen atoms such as fluorine, bromine and chlorine, and a cyano group.
In the general formula (4), R ² is the same or different from each other and independently of each other an alkyl group having 1 to 3 carbon atoms, and examples thereof include a methyl group, an ethyl group, and a propyl group.
In the method for producing a silicone having a terminal amino group represented by the general formula (1) and another terminal functional group, the compound represented by the general formula (4) is desilylated.

In the production method of the present invention, even when an acid is allowed to act on the compound represented by the general formula (4), the siloxane chain is hardly broken and the silyl group is selectively desilylated. The target compound represented by (1) can be produced with high purity.

This desilylation reaction is carried out in alcohol or water, preferably in alcohol.
The amount of alcohol may be appropriately adjusted and is not particularly limited. For example, it may be half to twice the mass of the silicone precursor having a terminal amino group and other terminal functional groups, and is approximately the same amount as the silicone precursor having a terminal amino group and other terminal functional groups. Is good. As the alcohol, methanol, ethanol, isopropyl alcohol, 1-propanol, isobutanol, 1-butanol and the like are preferably used. In particular, isopropyl alcohol is preferred.

The desilylation reaction is preferably carried out in the presence of an acid catalyst. The acid catalyst is not particularly limited as long as it is a catalyst conventionally used for desilylation. Particularly preferably, a weak acid having an acid dissociation constant (pKa) in water of 2.0 or more is preferable in order to suppress the cleavage of the siloxane chain. Specific examples include solid acid catalysts such as acetic acid, acrylic acid, paranitrobenzoic acid, fumaric acid, and carboxylic acid type. In particular, acetic acid is most preferred. The amount of the acid catalyst is not particularly limited. For example, when a weak acid such as acetic acid is used, it is 0.1 to 5.0% by weight, preferably 0.5 to 2.0% by weight, based on the silicone precursor having a terminal amino group and another terminal functional group. Is preferred.

This desilylation reaction can also be carried out at room temperature, but in that case, a large amount of acid is required to complete the reaction. Therefore, it is better to desilylate under heating using a relatively small amount of acid. The reaction conditions for desilylation are not particularly limited, and may be conventionally known conditions. The reaction temperature is, for example, a temperature in the range of 40 to 100 ° C., preferably 50 to 80 ° C. If the temperature is lower than this, a large amount of acid is required to complete the reaction, and there is a risk of reducing the reaction efficiency or siloxane chain scission. Evaporation can reduce product purity and yield. The reaction time may be, for example, 0.5 to 48 hours, preferably 1 to 6 hours.

As an example of the production method of the present invention, the silicone represented by the general formula (4) is diluted with the same mass of isopropyl alcohol, and 1.0 mass% with respect to the silicone represented by the general formula (4). Add acetic acid. The desilylation is completed by stirring at 80 ° C. for 3 hours. When the obtained silicone having a terminal amino group and other terminal functional groups has a low molecular weight, it can be confirmed by GC (gas chromatography) measurement that the reaction has been completed. In addition, when the silicone having the terminal amino group and other terminal functional groups obtained has a high molecular weight, it is confirmed that the reaction is completed by checking the amount of silylated isopropyl alcohol produced by the reaction by GC measurement. it can. Heating for a long time after completion of the reaction is not preferable because the purity of the target terminal amino group and silicone having other terminal functional groups may be lowered. After confirming the completion of the reaction, hydrotalcite (trade name: KYOWARD (registered trademark) 500, manufactured by Kyowa Chemical Industry Co., Ltd.) 5 times the mass of the acid used was added to the reaction solution and stirred at room temperature for 1 hour. Then, neutralizing the acid, removing hydrotalcite by filtration with filter paper, and distilling off isopropyl alcohol that worked as a solvent from the filtrate under reduced pressure, the terminal amino group represented by the above general formula (1) and other Silicones having terminal functional groups are obtained. This method is very simple and the resulting silicone with terminal amino groups and other terminal functional groups is of high purity.
As described above, high purity in the present invention has a specific structure (that is, m is a specific integer, and X, R ¹ , R ^2, and R ³ are each a specific 1 The compound (which is a kind of group) has a peak area of 90% or more, preferably 95% or more in the GPC or GC chromatogram.

B-ii) Production of silicone precursor having terminal amino group and other terminal functional group Next, the above-mentioned silicone raw material having terminal amino group and other terminal functional group represented by the above formula (1) A method for producing the compound represented by the formula (4) will be described. The compound represented by the above formula (4) is a hydrogen silicone represented by the following general formula (3):

(Wherein m, R ¹ and R ² are as described above)
It can be obtained by addition reaction of an organic functional group represented by the following formula (5) and a compound having a double bond.
CH ₂ = CH-X (5)
(Wherein X is as described above.)
Examples of the compound having an organic functional group and a double bond represented by the formula (5) include 2-allyloxyethanol (allyl glycol), diethylene glycol allyl methyl ether, dimethylallylamine, allyl chloride, allyl glycidyl ether, 3 -Butenoic acid and the like, and may contain acidic functional groups or basic functional groups other than those described above. By this method, the compound represented by the general formula (4) can be easily produced with high purity.

This addition reaction can be carried out without using a reaction solvent, but a reaction solvent is preferably used. Examples of the solvent include aliphatic hydrocarbon solvents such as hexane, methylcyclohexane, and ethylcyclohexane, aromatic hydrocarbon solvents such as toluene and xylene, alcohol solvents such as ethanol and isopropyl alcohol, and esters such as ethyl acetate and butyl acetate. Examples thereof include ether solvents such as dioxane, dibutyl ether and dimethoxyethane, ketone solvents such as methyl isobutyl ketone, and chlorine solvents such as chloroform. In particular, aromatic hydrocarbons such as toluene are most suitable. The amount of the solvent is not particularly limited and may be adjusted as appropriate.

This addition reaction is preferably carried out in the presence of a hydrosilylation catalyst. The hydrosilylation catalyst may be a conventionally known catalyst. For example, noble metal catalysts, in particular platinum catalysts derived from chloroplatinic acid, are suitable.

It is preferable to improve the stability of the platinum catalyst by completely neutralizing the chlorine ion of chloroplatinic acid with sodium bicarbonate. For example, a complex (karsted catalyst) of 1,1,3,3-tetramethyl-1,3-divinyldisiloxane and a neutralized sodium bicarbonate of chloroplatinic acid is most suitable as a reaction catalyst.

The addition amount of the hydrosilylation catalyst may be a catalyst amount for causing the addition reaction to proceed. For example, a complex of 1,1,3,3-tetramethyl-1,3-divinyldisiloxane and a neutralized multilayered product of chloroplatinic acid is converted into platinum with respect to the mass of the compound represented by the general formula (3). The amount is from 5 ppm to 80 ppm. A small amount of catalyst is not preferable because the reaction rate is slow. Also, if the amount of the catalyst is too large, the reaction rate is not particularly improved and it becomes uneconomical.

The temperature of this addition reaction is not particularly limited and may be adjusted as appropriate. In particular, the temperature is 20 ° C to 150 ° C, more preferably 50 ° C to 120 ° C. All the raw materials for this reaction can be charged and reacted together. However, more preferably, the compound represented by the formula (5), the reaction solvent, and the hydrosilylation catalyst are charged into the reactor, and then the compound represented by the general formula (3) is dropped and reacted. The temperature of the reaction solution at the time of dropping is particularly preferably around 80 ° C to 90 ° C. The reaction time is, for example, 1 to 12 hours, preferably 3 to 8 hours.

The amount of the compound having both the organic functional group represented by the formula (5) and the double bond is preferably an amount that is an excess mole relative to the compound represented by the general formula (3). For example, an amount ratio of 1.01 to 3 mol, preferably 1.05 to 2 mol, more preferably 1.1 to 1.5 mol is preferable with respect to 1 mol of the compound represented by the general formula (3).

After completion of the dropwise addition of the compound represented by the general formula (3), for example, after aging at 80 to 90 ° C. for 2 hours, the presence or absence of the unreacted compound represented by the general formula (3) is analyzed by, for example, gas chromatography (GC) This is confirmed by the disappearance of the peak. Next, a reaction solvent such as toluene and an excessively charged unreacted compound of the formula (5) are stripped at an internal temperature of 130 ° C., whereby the compound represented by the general formula (4) is obtained with high purity. It is done.

B-iii) Production of hydrogen silicone Next, a method for producing the compound hydrogen silicone represented by the formula (3) will be described. The compound represented by the above formula (3) is a dihydrogen polysiloxane represented by the following general formula (2):

(Wherein m and R ¹ are as described above)

(Wherein R ² is as described above)
And an addition reaction. This addition reaction is preferably carried out in accordance with the reaction conditions described in the section “ii) Production of silicone precursor having terminal amino group and other terminal functional group”.
The compound represented by the above formula (3) can be obtained by rectifying this adduct by distillation. By this method, the compound represented by the general formula (3) can be easily produced with high purity.

These may be used alone or in combination of two or more.

The copolymerization of the compound of the present invention and the other polymerizable monomer may be performed by a conventionally known method. For example, it can be carried out using a known polymerization initiator such as a thermal polymerization initiator or a photopolymerization initiator. Examples of the polymerization initiator include 2-hydroxy-2-methyl-1-phenyl-propan-1-one, azobisisobutyronitrile, azobisdimethylvaleronitrile, benzoyl peroxide, tert-butyl hydroperoxide, cumene And hydroperoxide. These polymerization initiators can be used alone or in admixture of two or more. The blending amount of the polymerization initiator is 0.001 to 2 parts by mass, preferably 0.01 to 1 part by mass with respect to 100 parts by mass of the total of the polymerization components.

Further, the polymer containing a repeating unit derived from the silicone compound of the present invention has a sufficient siloxane content, and therefore has excellent oxygen permeability. Therefore, it is suitable for manufacturing ophthalmic devices such as contact lenses, intraocular lenses, and artificial corneas. The manufacturing method of the ophthalmic device using the polymer is not particularly limited, and may be a conventional ophthalmic device manufacturing method. For example, when forming into a lens shape such as a contact lens or an intraocular lens, a cutting method or a mold method can be used.
