Title:
METHOD FOR PRODUCING CYCLIC OLEFIN COPOLYMER
Document Type and Number:
Japanese Patent JP2006016533
Kind Code:
A
Abstract:

To provide a copolymerization catalyst system industrially more simply synthesizable and having high polymerization activity and high copolymerizability and to provide a method for producing a copolymer of an α-olefin and a cyclic olefin using the catalyst.

A 2-20C α-olefin is copolymerized with at least one kind of cyclic olefin in the presence of the polymerization catalyst. Furthermore, the polymerization catalyst is composed of a transition metal compound (A) represented by formula (1) (wherein, M is a group 5 transition metal of the periodic table; X1 and X2 are each a hydrogen and a 1-20C alkyl group, an aryl group, an aralkyl group or a halogen; R1, R2, R3s, R4, R5 and R6s are each a hydrogen, a halogen or a 1-20C alkyl group, an aryl group or an aralkyl group; and m and n are each an integer of 0-3) and one or more kinds of activators (B) selected from an organoaluminumoxy compound or an organoboron compound. Thereby, the cyclic olefin copolymer is produced.
