The invention provides a composition comprising a first composition, which first composition comprises the following: A) a first interpolymer comprising, in polymerized form, ethylene, an α-olefin and a nonconjugated polyene; B) a second interpolymer comprising, in polymerized form, ethylene, an α-olefin and a nonconjugated polyene; and wherein the first composition has at least one of the following features: a) an [(ML(1+4, 125° C.))/Mw(conv)]*1000 greater than 0.429 mole/g; b) a Mooney Viscosity (ML, 1+4, 125° C.) greater than, or equal to, 70, and has a low shear viscosity (&eegr; at 0.1 rad/sec) less than, or equal to, 100,000 Pa·sec; and c) a Mooney Viscosity (ML(1+4, 125° C.)) greater than, or equal to, 70, and has an [Mw(abs)]/[Mw(conv)] less than 1.2. |
