Abstract
Disclosed are novel compositions of ethylene and/or α-olefin/vinyl or vinylidene interpolymers and an organic acid and a filler. Also disclosed are compositions including ethylene and/or α-olefin/vinyl or vinylidene interpolymers, an organic acid, various processing agents, coupling agents and a filler. The compositions disclosed herein are particularly useful in sound management applications, or as insulators.
