To obtain the subject resin composition excellent in impact resistance, weathering resistance, and heat resistance by incorporating a resin composition containing units of monomers of an aromatic vinyl, vinyl cyanide, and an epoxy- containing vinyl with a modified polyolefin polymer and a maleimide copolymer.
There is provided a composition comprising 10-94 wt.% resin composition comprising (A) a copolymer containing aromatic vinyl monomer units, vinyl cyanide monomer units, and epoxy-containing vinyl monomer units or a composition comprising A and (B) comprising aromatic vinyl monomer units and vinyl cyanide monomer units, wherein the units of the epoxy-containing vinyl monomer is present in an amount of 0.1-10 wt.% based on 100 pts.wt. A when the composition contains no B, and based on 100 pts.wt. A and B when the composition contains B, 5-40 wt.% polyolefin polymer modified with 0.1-10 wt.% unsaturated dicarboxylic anhydride or an unsaturated carboxylic acid monomer units, and 1-50 pts.wt. malemide copolymer comprising units of an unsaturated dicarboxylic acid imide derivative monomer and units of a vinyl monomer.
