PROBLEM TO BE SOLVED: To obtain a composition being capable of providing an article which is excellent in impact resistance, rigidity and chemical resistance, by compounding a thermoplastic resin made of a rubber-modified styrene resin, a resinous polymer, a non-polarα-olefin (co)polymer, and a vinyl (co)polymer, and a styrene/acrylic ester/carbon monoxide terpolymer. SOLUTION: The composition is obtained by compounding 100 parts by weight of a mixture made of 5 to 100 wt.% of a rubber-modified styrene resin ad 95 to 0 wt.% of a resinous polymer obtained by (co)polymerizing an aromatic vinyl compound, such as styrene or the like, a vinyl cyanide compound such as acrylonitrile or the like, and the like, 0.1 to 10 parts by weight of a thermoplastic resin made of 30 to 80 wt.% of a (co)polymer of a non-polarα-olefin such as styrene or the like, and 70 to 20 wt.% of a vinyl (co)polymer, and 0.1 to 8 parts by weight of an ethylene/acrylic ester/carbon monoxide terpolymer having a melting point of 40 to 80 deg.C. The rubber-modified styrene resin is obtained by (co)polymerizing styrene in the presence of a rubbery polymer such as polybutadine or the like. |
