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

摘要

TITLEORGANIC ACID CONTAINING FILLED ANDPLASTICIZED THERMOPLASTIC COMPOSITIONSBASED ON ETHYLENE INTERPOLYMERSABSTRACT OF THE DISCLOSUREFilled thermoplastic compositions havingenhanced elongation and useful, e.g., assound-deadening sheeting for automotive carpet, areobtained by blending about 0-50% by weight of anethylene interpolymer, such as ethylene/vinyl ester,ethylene/unsaturated mono- or dicarboxylic acids oresters of said unsaturated acids, etc.; 0-20% byweight of a plasticizer selected from the groupconsisting of processing oils, epoxidized oils,polyesters, polyethers, polyether esters andcombinations thereof; about 40-90% by weight offiller; from about 0.05 to about 5.0% by weight of atleast one organic acid or acid derivative selectedfrom the group consisting of saturated polycarboxylicacids having from 6 to 54 carbon atoms, unsaturatedmono- and dicarboxylic acids having from 12 to 20carbon atoms, alicyclic and aromatic carboxylic acids,and mono-, di- and trivalent metal salts, esters andamides of said acids; and optionally modifyingresins, such as tackifiers and certain ethylene andpropylene homo- and copolymers.
