摘要:
An object of the present invention is to propose a novel thermoplastic resin composition capable of exhibiting high impact resistance using an impact modifier isolated as a resin powder without coarsening or agglomeration. A thermoplastic resin composition includes 100 parts by weight of a thermoplastic resin (a) and 0.5 to 20 parts by weight of an impact modifier (b) containing a graft copolymer (b-1) containing a butadiene rubber polymer and a rigid shell, a water-soluble polymer compound (b-2) having a physical gel-forming property, and a gelling agent (b-3). In the thermoplastic resin composition, the content of the water-soluble polymer compound (b-2) having the physical gel-forming property is 0.01 to 3.0 parts by weight relative to 100 parts by weight of the graft copolymer (b-1) and the content of the rigid shell in the graft copolymer (b-1) is 1 to 20 percent by weight.
