Abstract
Elastomeric compositions produced by curing a blend of (A) ethylene/alphaolefin/nonconjugated polyene terpolymer; and (B) acrylonitrile/conjugated diene copolymer, utilizing a curing agent comprising sulfur, a sulfur cure accelerator and a peroxide curative exhibit desirable properties. Also disclosed is a process for preparing such elastomers.
