Abstract
A propylene-α-olefin-diene (PEDM) terpolymer may comprise 75 to 95 wt % propylene, 5 to 20 wt % α-olefin, and 0.5 to 5 wt % diene, said wt % based on the weight of the PEDM terpolymer. The propylene-α-olefin-diene terpolymer may be blended with an ethylene-based copolymer and optionally a variety of additives to form an elastomeric composition. An exemplary elastomeric composition includes 5 to 40 parts by weight per hundred parts by weight rubber (phr) of the PEDM terpolymer, 60 to 95 phr of the ethylene-based copolymer, and optionally additives like carbon black, zinc dimethacrylate, paraffinic oil, zinc oxide, and/or zinc stearate.
