PURPOSE:To obtain a thermoplastic resin composition which is prepared by mixing a specific imidized copolymer and a polyamide resin modified with a monoamine so that the terminal groups keep a specific concentration ratio, thus showing heat resistance, chemical resistance and moldability. CONSTITUTION:The thermoplastic resin composition is prepared by melt- kneading (A) 10-80% of imidized copolymer from 30-70wt.% of an aromatic vinyl monomer (preferably styrene), 30-60wt.% of an unsaturated dicarboxylic imide derivative (preferably N-phenylmaleimide), 1-10wt.% of an unsaturated carboxylic anhydride (preferably maleic anhydride) and 0-40wt.% of other copolymerizable unsaturated vinyl derivative and (B) 20-90% of a polyamide resin in which the concentration ratio of terminal NH2 to terminal COOH is adjusted to 1.1 to 10 using l/100 to l/1,000 mole of an aliphatic primary monoamine of 3-20 carbon atoms based on l mole of the monomer. |
