Articles having wood-like properties and appearance are obtained from compositions comprising 5-55% by weight of an ethylene interpolymer, such as ethylene/vinyl ester, ethylene/unsaturated mono- or dicarboxylic acids or esters or salts of said unsaturated acids, etc.; 1-15% by weight of at least one plasticizer selected from the group consisting of processing oils, epoxidized oils, polyesters, polyethers and polyetheresters; 20-90% by weight of cellulosic filler or mixture of cellulosic filler and mineral filler; 0-10% by weight of at least one additive, such as organic acid, organic acid derivative and surface active agent; and 0-44% by weight of certain ethylene and propylene homo- and copolymers.

Articles having leather-like appearance are obtained from compositions comprising 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, ethylene/.alpha.-olefin copolymers, etc.; 1-15% by weight of at least one plasticizer selected from the group consisting of processing oils, epoxidized oils polyesters, polyethers and polyetheresters; 20-90% by weight of cellulosic filler or mixture of cellulosic filler and mineral filler; 0-10% by weight of at least one additive, such as organic acid, organic acid derivative and surface active agent; and 0-27.5% by weight of elastomeric polymer.

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.

Filled and plasticized blends of linear low density polyethylene

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.
