    • 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, a 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.
    • 提供一种用于聚合乙烯基化合物的新型催化剂,其包含作为催化剂组分(A)的下述通式(1)表示的有机金属络合物:其中Cp1和Cp2独立地为取代或未取代的 环戊二烯基; R1是选自亚烷基或碳原子数为1〜20的芳基亚烷基,二烷基亚二甲苯基,二烷基亚甲基,烷基亚膦基或烷基亚氨基,R1交联Cp1和Cp2; m为0或1; M是钛,锆或铪; 和R 2,R 3和R 4独立地为氢,1至12个碳的烃基,烷氧基或芳氧基,以及由通式(2)或(3)表示的催化剂组分(B) (2)(3)其中n是4至60的整数,R5是烃基。 还提供了一种制备使用上述催化剂的乙烯基化合物聚合物的方法。
