摘要:
The present disclosure provides a composition. The composition can be formed into a foam composition. In an embodiment, the composition includes a neat ethylene/propylene/nonconjugated polyene interpolymer. The neat ethylene/propylene/non-conjugated polyene interpolymer includes from greater than 6.0 wt % to 15.0 wt % nonconjugated polyene. The neat ethylene/propylene/nonconjugated polyene interpolymer has 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 (RR) from 35 to 65; (iv) a Mw/Mn from 2.2 to 3.5; and (v) a Mw
