Abstract
Filled thermoplastic compositions useful, e.g., as sound-deadening sheeting for automotive carpet are obtained by blending about 5-55% by weight of an ethylene interpolymer, such as ethylene/vinyl ester, ethylene/unsaturated mono- or dicarboxylic acids or esters of said unsaturated acids, etc.; about 1-15% by weight of a plasticizer selected from the group consisting of polyesters, polyethers, polyether esters and combinations thereof with processing oil; about 40-90% by weight of filler; and optionally modifying resins, such as unvulcanized elastomeric polymers and certain other ethylene and propylene homo- and copolymers.
