ABSTRACT:
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: ##STR1## where Cp.sup.1 and Cp.sup.2 are independently a substituted or unsubstituted cyclopentadienyl group; R.sup.1 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 R.sup.1 crosslinking Cp.sup.1 and Cp.sup.2 together; m is 0 or 1; M is titanium, zirconium, or hafnium; and R.sup.2, R.sup.3, and R.sup.4 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) ##STR2## where n is an integer of from 4 to 60, and R.sup.5 is a hydrocarbon group. A process for producing a vinyl compound polymer which employs the catalyst defined above is also provided.
