摘要
A ring-opened metathesis copolymer formed by the ring-opening metathesis copolymerization of a cycloolefin monomer having a carboxylic anhydride group selected from bicycloheptene derivatives, tetracyclododecene derivatives and hexacycloheptadecene derivatives with a cycloolefin monomer selected from bicycloheptene derivatives, tetracycloheptene derivatives and hexacycloheptene derivatives; and a hydrogenation product of the copolymer. This copolymer is produced by using a polymerization catalyst comprises an organoruthenium compound having a heterocyclic carbene compound as a ligand. The ring-opened metathesis copolymer and the hydrogenation product thereof have a low dielectric constant, a low water absorption, a high adhesion to metals and a high heat resistance.
