The present invention relates to fillers and plasticized mixtures of ethylene / alkyl acrylate copolymers produced by tubular reactor modified with organic acids, consisting essentially of (a) from about 1 to about 50% by weight of at least one copolymer of ethylene / alkyl acrylate produced by tubular reactor; (b) from about 1 to 20 percent by weight of at least one plasticizer selected from the group consisting of process oils, epoxidized oils, polyester, polyethers, and polyether esters; (c) from about 40 to about 90% by weight 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 saturated or unsaturated mono- and polycarboxylic acids having 6 to 54 carbon atoms, and mixtures thereof. themselves; and optionally (e) from 0 to about 5% by weight of tackifying agent. Sound control sheets comprising these compositions are also described. Carpets, especially automotive carpets, having back coverings comprising these compositions are also described. |
