Cyclic olefin copolymer and curable composition

Abstract

A cyclic olefin copolymer has a structure as shown in Formula (I-1) or Formula (I-2): Formula (I-2), wherein R1 is R2 is hydrogen, halogen or C1-C6 alkyl, R3 and R4 are independently selected from the groups consisting of hydrogen, C1-C6 alkyl, phenyl group and CF3 group, n is a positive integer from 5 to 200, m is a positive integer from 5 to 200. The cyclic olefin copolymer is suitable for the preparation of a cured product of cyclic olefin copolymer with high processability, high heat resistance, good dielectric ability and high toughness and flame retardancy. A curable composition is also provided.
