Patent ID: 7956117

Claim:
A polypropylene-based composite composition comprising a) 30 to 70 weight percent of a polypropylene-based resin; b) 10 to 20 weight percent of a polyolefin based thermoplastic elastomer; c) 10 to 30 weight percent of a mineral filler; and d) 10 to 20 weight percent of an acrylate based functional polymer additive, wherein the acrylate based functional polymer additive includes a polyacrylate copolymer and a polyolefin, wherein the polyacrylate copolymer is dispersed in the polyolefin and the polyacrylate copolymer is a copolymer of butylacrylate, hydroxypropylacrylate and methylmethacrylate; and the weight percentages are based on the total weight of the polypropylene-based composite composition.
