THERMOPLASTIC RESIN COMPOSITION AND METHOD FOR PRODUCING THERMOPLASTIC RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition excellent in heat resistance and coating properties. SOLUTION: The thermoplastic resin composition includes: (A) 10-90 pts.mass of a polyamide; (B) 90-10 pts.mass of a styrene-based resin comprising: a graft copolymer obtained when a styrene-based monomer and one or two or more monomers copolymerizable with the styrene-based monomer is graft polymerized with a rubber polymer; and a copolymer obtained when an unsaturated nitrile monomer is copolymerized with one or two or more monomers copolymerizable with the unsaturated nitrile monomer, wherein the styrene-based resin includes 5-50 mass% of the rubber polymer of the total and 30-50 mass% of the unsaturated nitrile monomer in an acetone-soluble part; and (C) 1-50 pts.mass of a copolymer including an unsaturated carboxylic acid anhydride, a maleimide monomer, and an aromatic vinyl monomer based on the total 100 pts.mass of the (A) and the (B).
