Beschreibung
Zusammenfassung:	The invention provides a composition comprising the following: A) an ethylene/α-olefin/diene interpolymer; B) an ethylene/α-olefin copolymer with a Mooney Viscosity [ML(1+4) at 125° C.] greater than 40; and C) a peroxide; and wherein the α-olefin of the ethylene/α-olefin copolymer of component B comprises at least four carbon atoms; and wherein component A is present in an amount from 50 to 95 weight percent, based on the sum weight of components A and B.
