Methods for manufacturing cyclic olefin copolymers, resin compositions, molded articles, and cyclic olefin copolymers.

Abstract

The cyclic olefin copolymer of the present invention is characterized by comprising structural units (A) derived from chain olefins having 2 or more but less than 10 carbon atoms, structural units (B) derived from cyclic olefins, and structural units (C) derived from aromatic ethylene compounds, wherein the proportion of the chain portion of the aforementioned structural unit (C) is 40% or less. Furthermore, the resin composition of the present invention comprises the cyclic olefin copolymer of the present invention. Furthermore, the molding system of the present invention forms the resin composition of the present invention. Moreover, the method for manufacturing the cyclic olefin copolymer of the present invention comprises a step of copolymerizing chain olefins having 2 or more but less than 10 carbon atoms, cyclic olefins, and aromatic ethylene compounds in the presence of a catalyst containing a specified metallocene compound.
