PURPOSE:A composition improving the balance of the surface gloss, heat resistance,and processing characteristics without damaging properties of a resin, obtained by adding a polyester to a rubber reinforced resin consisting of nondiene type rubber, aromatic vinyl compound, and vinyl cyanide compound. CONSTITUTION:(A) 50-90wt% rubber reinforced resin having a rubber content in the rubber reinforced resin of 10-60wt% and a content of a vinyl cyanide compound in the resin of 10-45wt%, comprising a graft polymer obtained by grafting a monomer mixture consisting of an aromatic vinyl compound, a vinyl cyanide compound, and other vinyl compound copolymerizable with them onto a nondiene type rubber or comprising the graft polymer and a polymer or copolymer obtained by polymerizing a monomer selected from the above-mentioned monomers is blended with (B) 10-50wt%, preferably 10-30wt% aromatic polyester, preferably polytetramethylene terephthalate. |
