Abstract
A chlorinated ethylene/.alpha.-olefin copolymer rubber which is a chlorinated product of an ethylene/.alpha.-olefin copolymer rubber having a vinylidene bond at the terminal of the molecule, the number of said vinylidene bond being 0.05 to 1.00 per 1,000 carbon atoms, which has a chlorine content of 20 to 40% by weight, and which has a Mooney viscosity [ML.sub.1+4 (121.degree. C.)] of 10 to 190; and a composition comprising the chlorinated ethylene/.alpha.-olefin copolymer rubber, (a) a reinforcing agent, (b) a softening agent, and (c) a vulcanizing agent.
