PURPOSE:To provide a composition of good dimensional stability and appearance, also with high falling-ball impact strength at weld, comprising AES resin, polypropylene resin and specific olefin polymer. CONSTITUTION:The objective composition comprising (A) an AES resin consisting of (i) 100-5wt% of a graft polymer composed of (a) ethylene-propylene rubbery copolymer and (b) aromatic vinyl compound, vinyl cyanide compound and other polymerizable monomer(s) and (ii) 0-95wt% of a copolymer composed of aromatic vinyl compound, vinyl cyanide compound and other polymerizable monomer(s), (B) polypropylene resin, and (C) an olefin-unsaturated carboxylic alkyl ester copolymer (e.g. ethylene and/or propylene-methyl acrylate copolymer) or unsaturated carboxylic acid-modified olefin polymer (e.g. dicarboxylic acid-modified ethylene or propylene polymer). |
