Disclosed are filled and plasticized blends of (a) from about 10 to about 79% by weight of at least one copolymer derived from copolymerization of ethylene and at least one additional copolymer selected from the group consisting of vinyl esters of saturated carboxylic acids wherein the acid moiety has up to 4 carbon atoms, unsaturated mono- or dicarboxylic acids of from 3 to 5 carbon atoms, salts of said unsaturated acids and esters of said unsaturated mono- or dicarboxylic acids wherein the alcohol moieties forming said esters have from 1 to 6 carbon atoms; (b) from about 1 to 20 percent by weight of at least one plasticizer selected from the group consisting of processing oils, epoxidized oils, polyesters, polyethers, and polyether esters; (c) from about 20 to about 60% by weight of hollow filler; (d) from about 0. 05 to about 5% by weight of at least one organic acid or acid derivative selected from the group consisting of dimer and trimer acids having from 36 to 60 carbon atoms, and mixtures thereof; and optionally (e) from 0 to about 5% by weight of tackifier. Also disclosed are sound management sheets that comprise these compositions. Also disclosed are carpets, especially automotive carpets, having backside coatings comprising these compositions; and construction panels comprising these compositions.
