Sixooordinate complex provides some advantage than known pentacoordinate title complex.For example sixooordinate complex has higher air stability at solid state, and this is saturated because of its coordination.Because the unstable (for example pyridine) of additional part, this title complex causes fast than phosphino-pentacoordinate body.Slow initiation is meant that having only a small amount of title complex is the actual catalytic activity that has, and has therefore expended the title complex of many addings.Use initiator faster, the add-on of this catalyzer reduces.Though can't confirm in theory in addition, can believe because again in conjunction with the unstable part relevant with phosphine, increasing more slowly of sixooordinate complex can change lower polymolecularity into.And the saturated species of coordination get better than its pentacoordinate body resemblance crystallization; Owing to the unstable (for example pyridine and chlorine) of the part in the sixooordinate complex, this title complex can reach the title complex that is difficult to obtain in the past, and can provide some higher title complex of the purity that obtains by different routes in addition.For example having triphenylphosphine to use sixooordinate complex as the pentacoordinate benzylidene of phosphine part can be with produced in high yields, and higher purity is arranged.By P (p-CF

3Pentacoordinate benzylidene as its phosphine part is difficult to obtain by present route.Though can't confirm in theory, can believe that this is because its requires to replace the stronger body part of giving with the more weak body part of giving.The metalepsy of the anion ligand in the sixooordinate complex is faster than corresponding pentacoordinate species (for example phosphine key).Though can't confirm in theory, can believe that this produced owing to requiring part to dissociate before anion ligand replaces.Therefore the rapid dissociative title complex of its neutral electron donor part can replace faster.

The polyolefin compositions that obtains, and can process with different variety of ways by parts or goods that their are made, for example reaction injection molded (RIM), resin transfer molding (RTM) and vacuum aided processing are as VARTM (VA RTM) and SCRMP (Seemann compound resin form method), open casting, rotational molding, rotational casting, winding filament and mechanical workout.These processing compositions are commonly known in the art.Various moulding and processing technology are for example at PCT publication WO97/20865, (on March 1st, 2002 submitted to U.S. provisional application № 60/360755, exercise question is " polymer processing method and a technology of using pentacoordinate or Hexacoordinated ruthenium or osmium metathesis catalyst ") in state, it is for reference that its disclosed content has been taken in this paper.
Metathesis reaction can carry out under the situation that is with or without the solvent existence.The examples of solvents that can be used in polyreaction comprises organically, proton or water-containing solvent, preferably they are inert under polymerizing condition.The example of these solvents comprises aromatic hydrocarbon, chlorinated hydrocarbon, ether, aliphatic hydrocarbon, alcohol, water and composition thereof.Preferred solvent comprises benzene, toluene, p-Xylol, methylene dichloride, ethylene dichloride, dichlorobenzene, chlorobenzene, tetrahydrofuran (THF), diethyl ether, pentane, methyl alcohol, ethanol, water or its mixture.Preferred solvent is a benzene, toluene, p-Xylol, methylene dichloride, ethylene dichloride, dichlorobenzene, chlorobenzene, tetrahydrofuran (THF), diethyl ether, pentane, methyl alcohol, ethanol or its mixture.Most preferred solvent is the mixture of toluene or benzene and methylene dichloride.The solubleness of the polymkeric substance that the polyreaction Shen forms is decided by solvent of selecting and the polymeric molecular weight that obtains.
Title complex of the present invention has clearly the part environment of definition, and can modify neatly and adjust activity level subtly, stability, the recovery of solubleness and these catalyzer is easy.The solubleness of carbene compound can be controlled by suitably selecting hydrophobic or hydrophilic part well known in the art.Required catalysts solubility depends on the solubleness of reaction substrate and reaction product largely.
Metal carbene title complex of the present invention has high trigger rate, can consume major part (if not being whole) and add the title complex in the reaction to.Therefore catalyst loss is less in metathesis reaction.Pentacoordinate initiator before opposite still remains the utilized thing (being unconverted monomer) that a greater number is arranged after reaction is finished.Owing to there are two kinds of pyridine ligands to exist rate of rise also slow.High trigger rate and low rate of rise make the polymkeric substance of generation and use pentacoordinate title complex in the past that narrower polymolecularity is relatively arranged.And can determine that heating can improve trigger rate.The thermal initiation of pentacoordinate title complex is recorded in US patent № 6107420, and this paper is for reference for its content income.In general, use the initiation of catalyzer of the present invention and/or metathesis polymerization speed to be subjected to catalyzer of the present invention contacted with the alkene class and the control of reacting by heating mixture method.In a result wondrous and that do not expect, the Tmax of the thermal initiation of catalyzer of the present invention is higher than the Tmax of former pentacoordinate catalyzer significantly.Though theoretical Shanghai does not determine that clearly in the reaction of using metathesis catalyst, if manufactured parts or goods are fill system type (promptly containing reinforcing filler, fiber, bead etc.), packing material can play heat sink.And behind the former pentacoordinate catalyzer-slaking often is essential, this is because the effect of the heat sink that filler systems produces.Use the ROMP polymerization of pentacoordinate catalyzer to be recorded in US patent № 5728785 in the presence of peroxide cross-linking agent, this paper is for reference for its content income.On the contrary, use the more internal heat of a large amount of generations of hexa-coordinate catalyzer of the present invention.This high Tmax has reduced the needs of back-slaking.Even it is crosslinked to need adding superoxide or some free radical to promote in addition, the degree of crosslinking in the part of use free radical mechanism has increased than the degree of crosslinking in the part of using pentacoordinate metathesis catalyst preparation in the past.And the transformation period is decided by top temperature.Use the catalyzer transformation period of the present invention to greatly reduce, therefore only need less catalyzer, have very big commercial benefits.Though also do not confirm in theory, higher Tmax explanation has more ring to be opened in the ROMP reaction, and maturity is better.Because the Tmax height, residue can utilize substrate almost not have, and illustrates that almost each molecule that can react has all been reacted.For example vinylidene is at high temperature more stable than alkylidene group owing to them, thereby is favourable.When protected NHC (for example saturated Imes part, as US temporary patent application № 60/288680 and 60/278311 record, this paper is for reference for its content income) when being added in the reaction mixture, can find that the peak value thermal discharge has remarkably increased.The time that reaches peak value has in addition significantly reduced.It is available for polymerization that peak value thermal discharge meaning has more catalyzer, illustrates that the remaining thing that utilizes approaches zero.Therefore even catalyzer of the present invention also has better conversion rate and character preferably when having filler and additive to exist.
For clarity sake, with reference to particularly preferred embodiment the present invention is specifically elaborated.But will be appreciated that these embodiments and embodiment just for the present invention is described, are not limitation of the scope of the invention.
