Olefin copolymer having functional group, production process thereof and rubber composition

摘要

An olefin copolymer having a functional group and having a structural unit (a) derived from ethylene, a structural unit (b) derived from an alpha-olefin having 3 to 12 carbon atoms, and a structural unit (c) derived from a cycloolefin, exhibits an intrinsic viscosity [eta] of 0.1 to 10 dl/g as measured in decalin at 135° C. and can be used in a rubber composition.
