摘要:
A norbornene open-ring polymer having a weight-average molecular weight of 500 to 1,000,000 in terms of polystyrene and a melting point of 140 DEG C or above is produced by polymerizing a norbornene monomer mixture comprising a polycyclic norbornene monomer by using a polymerization catalyst containing as the main component a compound of a Group 6 transition metal of the periodic table bearing at least one imido group and at least two substituents (A) selected from the group consisting of alkoxy, aryloxy, alkylamido and arylamido; and hydrogenation of this polymer gives a product of hydrogenation thereof having a melting point of 140 DEG C or above.

摘要:
A nitrile group-containing copolymer rubber which has a hydroxyl group, carboxyl group, or carbon-carbon double bond at an end carbon atom or on a carbon atom which bonds with the end carbon atom is provided. The nitrile group-containing copolymer rubber of the present invention is preferably obtained by a metathesis reaction. According to the present invention, a nitrile group-containing copolymer rubber which is excellent in cross-linkability can be provided.
摘要:
A copolymer formed by the ring-opening metathesis polymerization of a cycloolefinic monomer having a carboxylic anhydride group selected among cycloheptene derivatives, tetracyclododecene derivatives, and hexacycloheptadecene derivatives with a cycloolefinic monomer selected among bicycloheptene derivatives, bicycloheptene derivatives, tetracyclododecene derivatives, and hexacycloheptadecene derivatives; and a product of hydrogenation of the copolymer. In producing the copolymer, a polymerization catalyst is used which comprises an organoruthenium compound having a heterocyclic carbene compound as a ligand. The copolymer and the hydrogenated copolymer are reduced in permittivity and water absorption, have high adhesion to metals, and have excellent heat resistance.
