Cyclic olefin copolymer, cyclic olefin copolymer composition, molded article and optical component

Abstract

The present invention provides a cyclic olefin copolymer and a cyclic olefin copolymer composition that can improve the balance between moldability and birefringence of the obtained molded article, as well as a molded article and an optical component that can improve the balance between moldability and birefringence. A cyclic olefin copolymer comprises: a constituent unit (A) derived from at least two α-olefins selected from the group consisting of ethylene and α-olefins having
