PURPOSE: To provide the wheel cover, having good balance of rigidity, impact strength, heat resistance, etc., and high practical use value, which is produced by injection molding a thermoplastic resin composition obtained by blending specific amounts of a specific vinyl-based copolymer, a polyamide and a modified polyolefin.
CONSTITUTION: (A) 5-90wt.% vinyl-based copolymer obtained by polymerizing (i) 5-95wt.% one or more vinyl-based copolymers selected from an aromatic vinyl-based monomer and (meth)acrylic ester-based monomer with (ii) 5-95wt.% maleimide-based monomer of the formula (R1 to R3 are each H, halogen, etc.) and (iii) 0.05-50wt.% other vinyl-based copolymer copolymerizable with the component (i) and the component (ii) is blended with (B) 3-90wt.% polyamide, (C) 5-60wt.% modified polyolefin containing one or more functional groups of a carboxylic acid group, a carboxylic acid metal base and an acid anhydride group and optionally pigment, filler, thermal stabilizer, etc., to give a thermoplastic composition, which is injection molded to give the objective cover.
