Abstract
The invention provides a composition comprising a first composition that comprises an ethylene/alpha-olefin/non-conjugated polyene interpolymer that has the following properties: A) a Mw greater than, or equal to, 150,000 g/mole; and B) a peak area from 21.3 ppm to 21.8 ppm that is greater than, or equal to, 3.0 percent of the total integral area from 19.5 ppm to 22.0 ppm, as determined by 13C NMR; and wherein the first composition has a tan delta (190 C at 0.1 rad/sec) less than, or equal to, 1.0.
