摘要： A thermoplastic resin composition having an excellent moldability capable of producing a molded article having excellent chemical resistance, and in particular, an excellent chemical resistance in TD is provided. The thermoplastic resin composition of the present invention is a thermoplastic resin composition produced by blending 40 to 90 parts by weight of a vinyl copolymer (A) prepared by copolymerization of a vinyl monomer mixture (a) comprising at least 5 to 40% by weight of an aromatic vinyl monomer (a1), 30 to 80% by weight of an unsaturated alkyl carboxylate ester monomer (a2), and 10 to 50% by weight of a cyanated vinyl monomer (a3) and 10 to 60 parts by weight of a graft copolymer (B) prepared by graft copolymerization of a vinyl monomer mixture (b) comprising at least 10 to 30% by weight of an aromatic vinyl monomer (b1), 30 to 80% by weight of an unsaturated alkyl carboxylate ester monomer (b2), and 1 to 10% by weight of a cyanated vinyl monomer (b3) in the presence of a rubbery polymer (r); wherein acetone-soluble content (C) of the thermoplastic resin composition has a number average molecular weight of 65,000 to 90,000.
