PURPOSE:A molded plastic article, obtained by using a thermoplastic resin containing a copolymer of a specific aromatic vinyl monomer and an unsaturated dicarboximide, and having improved heat and gasoline resistance and dimensional stability. CONSTITUTION:A molded article of interior trim part for automobiles obtained by incorporating (A) 10-100wt% copolymer containing 35-80wt% aromatic vinyl monomer residues and 20-65wt% unsaturated dicarboximide derivative residues with (B) 0-60wt% graft copolymer prepared by grafting 30-90pts.wt. monomeric mixture consisting of 40-85wt% aromatic vinyl monomer, 15- 40wt% vinyl cyanide monomer and 0-40wt% vinyl monomer copolymerizable therewith onto 10-70pts.wt. rubber-like polymer. Styrene, alpha-methylstyrene monomer or acrylonitrile is preferably used in the component (B), and the molded article is used as an instrument panel or meter hood, etc.
