TITLE ORGANIC ACID CONTAINING FILLED AND PLASTICIZED THERMOPLASTIC COMPOSITIONS BASED ON ETHYLENE INTERPOLYMERS ABSTRACT OF THE DISCLOSURE Filled thermoplastic compositions having enhanced elongation and useful, e.g., as sound-deadening sheeting for automotive carpet, are obtained by blending about 0-50% by weight of an ethylene interpolymer, such as ethylene/vinyl ester, ethylene/unsaturated mono- or dicarboxylic acids or esters of said unsaturated acids, etc.; 0-20% by weight of a plasticizer selected from the group consisting of processing oils, epoxidized oils, polyesters, polyethers, polyether esters and combinations thereof; about 40-90% by weight of filler; from about 0.05 to about 5.0% by weight of at least one organic acid or acid derivative selected from the group consisting of saturated polycarboxylic acids having from 6 to 54 carbon atoms, unsaturated mono- and dicarboxylic acids having from 12 to 20 carbon atoms, alicyclic and aromatic carboxylic acids, and mono-, di- and trivalent metal salts, esters and amides of said acids; and optionally modifying resins, such as tackifiers and certain ethylene and propylene homo- and copolymers.
