Abstract
Abstract An efficient process for producing cycloolefin polymer and cycloolefin/α-olefin copolymer without causing any ring opening of the cycloolefin; novel cycloolefin/α-olefin copolymer produced thereby; and composition and molding prepared from said copolymer. The production process comprises conducting the homopolymerization of cycloolefin or the copolymerization thereof with α-olefin in the presence of a catalyst based on the following components (A) and (B) or (A), (B) and (C); A: transition metal compound, B: compound which forms ionic complex by the reaction with transition metal compound, and C: organoaluminum compound.
