ORGANIC ACID CONTAINING FILLED AND PLASTICIZED THERMOPLASTIC COMPOSITIONS BASED ON ETHYLENE INTERPOLYMERS

摘要

TITLE ORGANIC ACID CONTAINING FILLED AND PLASTICIZED THERMOPLASTIC COMPOSITIONS BASED ON ETHYLENE INTERPOLYMERS 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.
