<p>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: <CHEM> where Cp<1> and Cp<2> are independently a substituted or unsubstituted cyclopentadienyl group; R<1> is an alkylene or arylalkylene group having 1 to 20 carbons, a dialkylsilylene , dialkylgermanylene, alkylphosphinediyl, or alkylimino group, linking Cp<1> and Cp<2>; m is 0 or 1; M is titanium, zirconium, or hafnium; and R<2>, R<3>, and R<4> are independently hydrogen, a hydrocarbon group of 1 to 12 carbons, an alkoxy or aryloxy group, and a catalyst component (B) represented by the general formula (2) or (3) <CHEM> where n is an integer of from 4 to 60, and R<5> is a hydrocarbon group. A process for producing a vinyl compound polymer which employs the catalyst defined above is also provided.</p> |
