Patent ID: 8664322

Claim:
A thermoplastic resin composition comprising: about 100 parts by weight of a base resin comprising about 40 to about 90% by weight of a thermoplastic resin and about 10 to about 60% by weight of glass fibers having a cross-sectional aspect ratio of a long diameter of a cross section of the glass fibers and a short diameter of a cross-section of the glass fibers greater than or equal to about 1.5; and about 0.1 to about 10 parts by weight of a branched graft copolymer comprising polyolefin as a main chain, wherein the branched graft copolymer comprises a branch moiety in an amount of 15 to about 50% by weight, based on the total weight of the branched graft copolymer, wherein the branch moiety of the branched graft copolymer comprises acrylate, modified-ester, arylate, acrylonitrile, or a combination thereof, and wherein the main chain of the branched graft copolymer comprises about 70 to about 100% by weight of polyethylene, polypropylene, or ethylene-propylene copolymer.
