Peroxide vulcanization of oil-extended elastomeric ethylene copolymers containing bromine

摘要

A peroxide curable composition of an elastomeric unsaturated ethylene/C3-C18 alpha -monoolefin/nonconjugated diene copolymer (EODM) containing at least about 0.1 weight percent allylic bromine, at least 20 phr of a hydrocarbon extending oil, about 1-5 phr (active ingredient) of an organic peroxide curing agent, and an unsaturated peroxide activator.
