Description
The present invention relates to polymers of hydro-carbon-substituted diacetylene compounds and in particular to conjugated polymers of such compounds. The present inven-tion also relates to hydrocarbon-substituted diacetylene com-pounds and their manufacture.
Diacetylene compounds arle capable of being polymer-ized to form conjugated polymers. Such polymers may be use-ful in a variety of applications, for example, in end uses utilizing the toughness, colour and/or the electrical proper-ties of such polymers. The polymers may have adva~tages overother known con~ugated compounds, for example anthracene der-ivatives as a result of the physical properties of the poly-mers.
Polymers of acetylenic compounds are known. F.
Bohlmann et al disclose the reaction products of polyynes of the formula Rl-(C-C)n- ~, where n is equal to or greater than 2, in Canadian Patent 679,842 which issued on February 11, 1964. The polyynes disclosed by Bohlmann et al are generally characterized by values of n equal to or in partic-ular greater than 2 and by substituents Rl and R2 which arepolar and/or which are con~ugated with the acetylenic bonds of the compound.
The polymerization of acetylenes having polar sub-stituents is also disclosed in German Offenlegungsschrift ; 1,940,691 of Badische Anilin and Soda-Fabrik, published Feb-ruary 25, 1971.
It has now been found that hydrocarbon-substituted diacetylenes having substituents that are neither polar nor conjugated with the acetylenic bond and the polymers derived therefrom may be manufactured.
Accordingly, the present invention provides diacetyl-enes of the formula: ~.
" - 1 . . .
. -`` ' ' . '' ` 1 ' ". "',.1 '`` '` :
~ 4 Rl-(CH2)8-C-c-c-c-~cH2)8-where Rl and R2 are hydrogen or hydrocarbon radicals, Rl and being the same or different.
The present invention also provides a process for the manufacture of diacetylenes of the formula:
Rl (CH2)8-C-C-C-C-(CH2)8-~2 where Rl and R2 are hydrogen or hydrocarbon radicals, Rl and R2 being tne same or different, c~mprising contacting monoacetyl-enes of the formula:
R-(CH2)8-C-C-H, where R is Rl or R2 with a cupric salt in an inert solvent in the presence of an amine, said cupric salt and said amine being soluble in said solvent and the ratio of monoacetylene : cupric ion being maintained at less than 1:3 on a molar basis, and separating the diacetylene so formed.
In a preferred embodiment of the process for the manufacture of the diacetylenes of the present invention, the .~ cupric salt is cupric acetate.
Furthermore, the present invention provides a polymer consisting essentially of the polymerization product of diacetyl-enes of the formula:
l (cH2)8-c--c-c--c-(cH2)g-R2 where Rl and R2 are hydrogen or hydrocarbon radicals, Rl and R2 being the same or different.
In a preferred embodiment of the polymer o~ the present invention Rl and R2 are alkyl groups and especially linear alkyl groups having 1-8 carbon atoms.
In another embodiment the polymer is a conjugated polymer.
In yet another embodiment all the diacetylenes are identical and in particular Rl and R2 are the same.
In additio~, the present invention provides a process for the polymerization of one or more diacetylenes of the formula:

Rl- ( CH2 )8-C--C-C--C- ( CH2 )8-R2 where R and R2 are hydrogen or hydrocarbon radicals, ~1 and R2 being the same or different, comprising the steps of crystal-lizing said diacetylenes, polymerizing the diacetylenes and separating the polymer so formed.
In a preferred embodiment of the process of the present invention the diacetylenes are polymerized using photo-initiation techniques especially with electromagnetic radiation of wavelength in, or less than, the visible range of the electro-magnetic spectrum The polymers of the present invention are obtainedby polymerization of diacetylenes of the formula:
R -(cH2)8-c-c-c-c-(cH2)8-R2 Rl and R2 having been defined hereinabove. These diacetylenes are capable of being polymerized at ambient temperatures. At such temperatures the diacetylenes of the above formula are capable of being crystallized and polymerization of the diacetyl-enes is preferably carried out with the diacetylenes in a crystallized form, i.e., in the solid state. In order for polymerization of crystallized diacetylenes to take place the acetylenic bonds of the diacetylene compounds must be aligned in a manner that facilitates polymerization. m e shape of - the diacetylene molecule will be an important factor in deter-mining the structure of the crystal formed therefrom and in particular whether the crystal structure is such that polymer-ization may readily occur. Polymerization to linear con~ug-` ated polymers is preferred. m e diacetylenes of the present invention, which are capable of being polymerized in the solid state, are characterized by substituted linear C8 alkyl radicals attached to each acetylenic group.

~.i , . .. ~ -~ 4 ~
The polymerization of the diacetylenes of the present invention is preferably carried out using photoinitiation tech-niques J such techniques being known in the art. The wavelength of the radiation used for photoinitiation may be varied over a wide range of the electromagnetic spectrum, especially radi-ation of wavelengths in, or less than, the visible range of the electromagnetic spectrum. For example, so-called soft X-rays, ultra-violet light and visible light may be used, as is exempli-fied hereinafter.
The substituents Rl and R2 are hydrocarbon radicals.
Such radicals may include alkyl radicals, especially linear alkyl radicals, or radicals containing aryl, cyclohexyl and olefinic groups. Alkyl radicals, especially linear alkyl radicals and in particular linear Cl-C8 alkyl radicals are preferred. The substituents Rl and R2 may be the same or different although it is preferred that Rl and R2 be the same.
The polymers of the present invention are con~ugated polymers. The properties of colour, toughness and high melting temperature, as illustrated hereinafter, make the polymer capable of use in a variety of end uses. The polymers may be useful in semiconductor electrical applications. The polymers are also capable of being blended with other polymers especially polymers of ethylene and the like.
The monomers from which the polymers of the invention may be manufactured may be obtained by the oxidative coupling of terminal monoacetylenes, i.e., R-(CH2)8-C-C-H, where R is the Rl or R2 of the polymer defined hereinabove. The oxidatlve coupling reaction is carried out in an inert solvent in the - presence of cupric salts soluble in the solvent. An example of a suitable cupric salt is cupric acetate. The solvent should ` - 4 -4 ~ 4 ~
contain an amine soluble in the solvent, e.g., pyridine, to maintain the solution in a mildly alkaline condition. A suit-able solvent mixture is diethyl ether/pyridine. The solvent mixture containing the cupric salt is refluxed and the mono-acetylene compound is slowly added pre~erably so that the ratio of cupric ion to monoacetylene is maintained greater than about 3. The product of the reaction may be separated from the reaction mixture by e~traction or by addition of the reaction mixture to an ice-dilute hydrochloric acid mix-ture and separation of the then solidified reaction product.
The oxidative coupling reaction may be used for the manufacture of diacetylenes in which Rl and R2, in the formula hereinabove, are hydrogen or a hydrocarbon radical.
One or more different hydrocarbon radicals may be used al-though in a preferred embodiment Rl and R2 are hydrogen or one type of hydrocarbon radical. In further embodiments R
and R2 are alkyl groups especially linear alkyl groups hav-ing 1-8 carbon atoms.

EXAMPLE II
Dotriaconta-15,17-diyne was dissolved in benzene and placed in a vessel capable of having an ultra-violet lamp inserted therein. The vessel was ~umbled from side to side and the benzene was removed under vacuum. ~he diyne crystal-lized over a large proportion of the inne~ surface of the vessel.
A low pressure mercury lamp (2.5 watts total power, principal wavelength 2540 A, obtained from Ace Glass Inc.) was inserted in the vessel and, after purging the vessel with nitrogen, the diyne was irradiated for about 7 hours. The diyne was re-dissolved in benzene which was then removed again under vacuum so as to renew the layer of diyne. The irradiation was repeated. The re-dissolutuon of diyne, removal of ben-zene and irradiation was repeated 10 times. The unreacted diyne was separated and the yield o~ polymer was shown to be 14~.
