<p>PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition enabling obtaining a molding having both high heat resistance and impact resistance, and external appearance with high quality (jet-black color, image sharpness and good weld external appearance) only by molding without coating.SOLUTION: A thermoplastic resin composition is such that: a dispersion phase comprising a graft copolymer (A), and a continuous phase (B) are included; the graft copolymer (A) has a trunk polymer comprising a resin polymer, and a graft chain graft polymerized with the trunk polymer; the graft chain has a cyanide vinyl-based monomer unit and at least one kind of monomer unit copolymerizable with the cyanide vinyl-based monomer unit; the distribution of a percentage content of the cyanide vinyl-based monomer unit in a component derived from the graft chain, obtained through oxidative decomposition of the graft copolymer (A) has prescribed two or more peaks; at least one glass transition point at each of less than 20°C and 20°C or more is included; and each of the glass transition point at 20°C or more is 100°C or more, and at least one glass transition point is included in a range of 120-140°C.</p> |
