POLYAMIDE-BASED THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE

PROBLEM TO BE SOLVED: To provide a polyamide-based thermoplastic resin composition which is well in balance of impact resistance, mechanical properties and heat resistance. SOLUTION: The thermoplastic resin composition is prepared by formulating (A) a polyamide resin, (B) a copolymer prepared by polymerizing an diene monomer, an aromatic vinyl monomer and a vinyl cyanide monomer, (C) a copolymer prepared by polymerizing an aromatic vinyl monomer and a vinyl cyanide monomer, and (D) a graft copolymer prepared by polymerizing a monomer mixture (D2) containing a vinyl monomer (d3) having a functional group selected from an acid group and an epoxy group as an essential component in the presence of a polyorganosiloxane-based rubber (D1), wherein (A)-(D) are formulated by the following ratio äthe total of (A)-(D) is 100 mass%: (A) 10-90 mass%; (B) 0.1-89.8 mass%; (C) 0.1-89.8 mass%; and (D) 0.1-89.8 mass%}.
