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 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.
由以下物质组成的混合物:(A) 高分子量弹性聚合物;(B) 足量的乙烯/α-烯烃/非共轭聚烯三元共聚物,其平均分子量在约 1,000 到约 15,000 之间,使混合物的粘度至少比单独成分(A)的粘度低约 5%;(c) 一种固化剂,具有更高的可加工性,固化后具有意想不到的拉伸强度、耐臭氧性和耐油性。
