METHOD FOR PRODUCING CYCLIC OLEFIN ADDITION COPOLYMER, CYCLIC OLEFIN ADDITION COPOLYMER AND ITS USE

Document Type and Number:

Japanese Patent JP2007332256

Kind Code:

A

Abstract:

To provide a method for producing a cyclic olefin addition copolymer.

A monomer composition containing 10-90 mol% 5-alkylbicyclo[2.2.1]hept-2-ene having a 10-12C alkyl group and 10-90 mol% bicyclo[2.2.1]hept-2-ene is subjected to an addition copolymerization using a catalyst containing a particular palladium compound. A highly economic method for preparing the cyclic olefin addition copolymer excellent in melt-molding processability, transparency, etc., with high productivity, the cyclic olefin addition copolymer showing high transparency, high heat resistance, high melt-molding processability, a low water-absorbing property, a low dielectric constant and a low metal content, and a film, sheet or an optical material obtained by molding the cyclic olefin addition copolymer are provided.
