CATALYST FOR COPOLYMERIZATION OF ALPHA-OLEFIN AND AROMATIC VINYL COMPOUND, PRODUCTION OF COPOLYMER OF ALPHA-OLEFIN AND AROMATIC VINYL COMPOUND, AND NEW TRANSITION METAL COMPOUND

摘要

PROBLEM TO BE SOLVED: To obtain a catalyst having a high copolymerization reactivity with an aromatic vinyl compound and a permittivity to broadly control its composition ratio and giving an -olefin/aromatic vinyl compound copolymer with high randomness, and to provide a method for preparing the catalyst. ;SOLUTION: This catalyst comprises a transition metal compound (A) shown by the formula (M¹ is Zr, Ti, Hf, etc.; M² and M³ are each Fe, etc.; Cp¹, Cp², Cp³ and Cp⁴ are each a group having a cyclopentadienyl skeleton; R¹ and R² are each a substituted silylene group, etc.; X, Y and Z are each a cyclopentadienyl group, etc.; and (n), (m) and (p) are each 1 to 5.), and an organoaluminumoxyl compound or organoboron compound (B). The producing method of the other objective -olefin/aromatic vinyl compound copolymer is to copolymerize an -olefin and an aromatic vinyl compound in the presence of this catalyst.;COPYRIGHT: (C)1998,JPO
