Claim 0:
1. A first composition comprising from 30 to 40 wt % of a first ethylene/α-olefin/diene interpolymer and from 60 to 70 wt % of a second ethylene/α-olefin interpolymer, and
wherein the first composition comprises from 0.1 to 1.0 wt % diene, based on the weight of the first composition, and
wherein the first composition comprises from 45 to 65 wt % ethylene, based on the weight of the first composition, and
wherein the first ethylene/α-olefin/diene interpolymer has a weight average molecular weight (Mw) from 250,000 to 500,000 g/mole, and a diene content from 0.40 to 0.60 wt % and has a C2 (polymerized ethylene) content from 55 to 80 wt %, based on the weight of the first ethylene/α-olefin/diene interpolymer, and
wherein the first composition has a weight average molecular weight (Mw) from 200,000 to 280,000 g/mole, a % crystallinity from 0.5% to 12% and has a “% Peak Area (21.3 to 22.0 ppm)” >5.0%, as determined by 13C NMR and the ratio of the C2 (polymerized ethylene) content of the first composition to the C2 (polymerized ethylene) content in the first ethylene/α-olefin/diene interpolymer is from 0.50 to 1.10; and wherein the ratio of the Mooney Viscosity (ML, 1+4, 125° C.) of the first composition to the Mooney Viscosity (ML, 1+4, 125° C.) of the first ethylene/α-olefin/diene interpolymer is from 0.75 to 1.05.
