The usage quantity of described Metallocenic compound can be general catalytic amount, particularly, polymerization is generally 1 to 0.001 weight part with polymerizable unsaturated compound 100 weight parts, is preferably 0.01 to 0.005 weight part.
In addition, among the present invention with the shared mercaptan compound of above-mentioned Metallocenic compound be, have the mercaptan compound of bridging property silyl, generally this mercaptan compound that contains the bridging property silyl is following formula HS-R 3Shown in compound.
Wherein, R 3For having the group of bridging property silyl, illustrative bridging property silyl during employed bridging property silyl is can congruent (A) illustrated, special good for being selected from least a kind of bridging property silyl in a group that forms by hydroxyl silyl, methoxy methyl silylation, (ethoxymethyl) silylation, propoxy-silyl, chloromethane silylation and silyl bromide base.R 3Concrete example as, 3-sulfydryl propyl group-Trimethoxy silane, 3-sulfydryl propyl group-triethoxyl silane, 3-sulfydryl propyl group-monomethyl dimethoxy silane, 3-sulfydryl propyl group-single phenyl dimethoxy silane, 3-sulfydryl propyl group-dimethyl mono methoxy silane, 3-sulfydryl propyl group-monomethyl diethoxy silane, 4-sulfydryl butyl-Trimethoxy silane and 3-sulfydryl butyl-Trimethoxy silane etc.
This mercaptan compound that contains the bridging property silyl mainly is to utilize organometallic compound to choose hydrogen atom and generate S-R when reaction 3Free radical, and make this free radical import at least one end of formed polymkeric substance.Therefore, the bridging property silyl that is directed to polymer ends like this can be owing to this reaction lose activity, the activity that silyl had that the former state maintenance is imported into.
Contain the mercaptan compound HS-R of bridging property silyl by this 3Break away from hydrogen atom and generate S-R 3Free radical, and this free radical and polymerizable unsaturated compound bonding, activation begin polymerization thus.In addition, use the purpose of above-mentioned Metallocenic compound to be, by the mercaptan compound HS-R that contains the bridging property silyl 3The hydrogen atom of choosing, and make the mercaptan compound activation that contains the bridging property silyl.So use the mercaptan compound HS-R that contains the bridging property silyl separately 3The time can obviously reduce percent polymerization, that is, use when containing the mercaptan compound of bridging property silyl in fact separately, polymerizable unsaturated compound will not react.In addition, the main application target of above-mentioned Metallocenic compound is, make the mercaptan compound activation that contains the bridging property silyl, general its structure is with the previous Metallocenic compound that uses, promptly exist in compound mode shown in the above-mentioned formula (1), but sometimes its part can and the mercaptan compound that contains the bridging property silyl, polymerizable unsaturated compound and their derivative bonding, in addition, reaction when carrying out this organometallic compound can decompose and make in the reactive system system and contain metal.
The above-mentioned usage quantity that contains the mercaptan compound of bridging property silyl can be done suitably to select under the characteristic of considering resulting polymers.That is, when increasing the concentration of the mercaptan compound that contains the bridging property silyl in the reactive system, can promote the percent polymerization of time per unit and arrive percent polymerization.Though increase the percent polymerization that the Metallocenic compound amount can promote time per unit this moment, do not have big influence to arriving percent polymerization.In addition, the usage quantity of Metallocenic compound influences hardly to the molecular weight of resulting polymers, but when not using Metallocenic compound, can't effectively react.In addition, when increasing the mercaptan compound usage quantity, can improve polymerization velocity.Because have this tendency, so be considered to composition of the present invention (B) with in the catalyzer, Metallocenic compound plays the effect of the whole deactivated catalyst of reaction, and mercaptan compound has polymerization initiation (polymerization causes the effect of planting).So composition of the present invention (B), contains the usage quantity decision molecular weight and the percent polymerization of the mercaptan compound of bridging property silyl with in the catalyzer.
