(57) [Summary] [Object] To provide a thermoplastic resin composition which is excellent in impact resistance, heat resistance, and surface layer peeling resistance, and retains appropriate fluidity when melted. [Structure] 100 parts by weight of an alloyed resin (X), which comprises 1 to 99 parts by weight of a vinyl chloride resin (D) and / or a styrene resin (E) and 99 to 1 parts by weight of a modified olefin resin (F), (D) and / or (E) and (F) compatibilizer (G) 0 to 50 parts by weight, graft copolymer (Y) 0.1 to 50 parts by weight, and heat resistance improver (Z) A thermoplastic resin composition containing 1 to 200 parts by weight. This graft copolymer (Y) is a vinyl compound (a-1) having an epoxy group and other vinyl compound group (a). 2 to 5 parts by weight of the vinyl compound group (A) consisting of Obtained by graft-polymerizing 40 to 95 parts by weight of the rubbery polymer (B); the heat resistance improver (Z) is a vinyl compound (c-1) having an epoxy group and other vinyl compound group (c-2). ) Is a copolymer obtained by copolymerization. |
