Claim 7:
8. A foam composition comprising:
a neat ethylene/propylene/nonconjugated polyene interpolymer comprising from greater than 6.0 wt % to 15 wt % nonconjugated polyene, the interpolymer having the following properties
(i) a molecular weight (Mw) from 240,000 to 270,000;
(ii) a Mooney viscosity (ML (1+4), 125° C.) from 85 to 95;
(iii) a rheology ratio from 35 to 65;
(iv) a Mw/Mn from 2.2 to 3.5; and
(v) a Mw<1389.6 [g/mol] MV+140,000 g/mol wherein Mw is the weight average molecular weight and MV is the Mooney Viscosity (ML 1+4, 125° C.).
