ABSTRACT:
Filled thermoplastic compositions useful as sound deadening sheeting having improved tensile elongation are obtained by blending about 5-60 percent by weight of a mixture of at least two copolymers of ethylene, having specified polar comonomer contents, about 40-90 percent by weight of filler, 0-15 percent by weight of plasticizer selected from the group consisting of processing oils, polyesters, polyethers and polyether esters, and optionally modifying resins such as elastomeric polymers and certain other ethylene and propylene homo- and copolymers.
