Catalyst for polymerization of vinyl compound

摘要

A novel catalyst for polymerization of a vinyl compound is provided which comprises, as a catalyst component (A), an organometal complex represented by General Formula (1) below: (1) where Cp1 and Cp2 are independently a substituted or unsubstituted cyclopentadienyl group; R1 is a group selected from alkylene groups or arylalkylene groups having 1 to 20 carbons, dialkylsillylene groups, dialkylgermanylene groups, alkylphosphinediyl groups, or alkylimino groups and R1 crosslinking Cp1 and Cp2 together; m is 0 or 1; M is titanium, zirconium, or hafnium; and R2, R3, and R4 are independently hydrogen hydrocarbon group of 1 to 12 carbons, an alkoxy group, or an aryloxy group, and a catalyst component (B) represented by the general formula (2) or (3) (2) (3) where n is an integer of from 4 to 60, and R5 is a hydrocarbon group. A process for producing a vinyl compound polymer which employs the catalyst defined above is also provided.
