Abstract
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 surface active agent such as sulfonates, sulfates, phosphates, etc.; and optionally, modifying resins, such as tackifiers and certain ethylene and propylene homo- and copolymers.
