Abstract
The invention provides a composition comprising a first composition that comprises at least one ethylene/alpha-olefin/nonconjugated polyene interpolymer; and wherein the first composition has a Mooney Viscosity (ML1+4, 125C) greater than, or equal to, 10, and wherein the first composition has a “13C NMR % Peak Area,” which is the {[(13C NMR peak area from 21.3 ppm to 21.8 ppm) divided by the (total integral area from 19.5 ppm to 22.0 ppm)]×100}, that is greater than 3.5 percent, as determined by 13C NMR.
