Abstract
Blends comprised of (A) a high molecular weight elastomeric polymer; (B) a sufficient amount of an ethylene/alphaolefin/nonconjugated polyene terpolymer having a number average molecular weight of between about 1,000 and about 15,000 such that the variety of the blend is at least about 5% lower than the viscosity of component (A) alone, and (c) a curative, exhibit increased processability, and, when cured, exhibit unexpectedly desirable tensile strength, ozone resistance and oil resistance.
