Filled thermoplastic compositions useful, e.g., as sound-deadening sheeting for automotive carpet are obtained by blending about 5-55% by weight of ethylene/ alpha -olefin copolymer, the alpha -olefin containing from 4 to 10 carbon atoms; about 2-12% by weight of plasticizer selected from the group consisting of processing oils, epoxidized oils, polyesters, polyethers and polyether esters; about 40-90% by weight of filler; and optionally elastomeric polymers.
