Abstract
Provided are compositions comprising: (a) an ethylene-propylene-diene terpolymer having a Mooney viscosity [ML(1+4) 125° C.] of about 25 to about 300 and an ethylene content of at least about 60 wt % of the ethylene-propylene-diene terpolymer; and (b) a polyolefin elastomer. The presence of the polyolefin elastomer improves rheological properties of the composition to an extent that does not significantly compromise other properties, such as tensile strength at break and compression set.
