  • Ethylene-Based Copolymer and Propylene-Alpha-Olefin-Diene Compositions for Use in Layered Articles
    Publication number: 20220290013
    Abstract: An elastomeric composition is provided that includes from 1 to 100 parts by weight per hundred parts by weight rubber (phr) of a first propylene-?-olefin-diene (PEDM) terpolymer comprising 70 wt % to 92.5 wt % propylene, 7.5 wt % to 30 wt % a C2 or C4-C12 ?-olefin, and 3.5 wt % to 20 wt % diene, said wt % based on the weight of the PEDM terpolymer. The PEDM terpolymer V may have a Mooney viscosity (ML(1+4)) of 25 MU to 100 MU. The composition may further include from 0 to 99 phr of an ethylene-based copolymer comprising 40 wt % to 95 wt % ethylene.
