Title:
COPOLYMERIZATION CATALYST AND METHOD FOR PRODUCING CYCLIC OLEFIN COPOLYMER
Document Type and Number:
Japanese Patent JP2002371109
Kind Code:
A
Abstract:

To provide an industrial and highly active catalytic system easily obtained in for copolymerization between an α-olefin and a cyclic olefin, and to provide a method for producing the copolymer by the use of the catalytic system.

This copolymerization catalytic system is obtained by combining a metal complex having one molecule of a ligand including a cyclopentadienyl skeleton of a specific structure and a specific monovalent bidentate chelate anionic ligand with an activator having a specific structure. The alternative method for producing the copolymer using the catalytic system is provided.
