The present invention pertains to a thermoplastic resin composition, a method for producing same, and a molded article including same. More specifically, the present invention pertains to: a thermoplastic resin composition characterized by containing (A) a polyester resin, (B) a vinyl cyan compound-conjugated diene compound-aromatic vinyl compound graft copolymer, (C) an alpha-methylstyrene-vinylcyan compound copolymer, (D) a maleimide-based polymer, and (E) an amide-based lubricant; a method for producing same; and a molded article including same. The present invention has the effect of providing: a thermoplastic resin composition which is very cost-effective and suitable for automobile interior materials, and has excellent heat resistance, chemical resistance, light resistance, and noise resistance while retaining mechanical properties equivalent to or better than conventional heat-resistance ABS resin compositions; a method for producing same; and a molded article including same. La présente invention concerne une composition de résine thermoplastique, un procédé de production associé et un article moulé la contenant. Plus spécifiquement, la présente invention concerne : une composition de résine thermoplastique caractérisée en ce qu'elle contient (A) une résine de polyester, (B) un copolymère greffé de composé cyan vinylique - composé de diène conjugué - composé vinyle aromatique, (C) un copolymère d'α-méthylstyrène-composé cyan vinylique, (D) un polymère à base de maléimide, et (E) un lubrifiant à base d'amide; un procédé de production associé; et un article moulé le comprenant. La présente invention a pour effet de fournir : une composition de résine thermoplastique qui est très économique et appropriée pour des matériaux intérieurs d'automobile, et présente une excellente résistance à la chaleur, une excellente résistance chimique, une excellente résistance à la lumière et une excellente résistance au bruit tout en conservant des propriétés mécaniques équivalentes ou supérieures à celles des compositions de résine ABS résistantes à la chaleur classiques; un procédé de production associé; et un article moulé la contenant. 본 발명은 열가소성 수지 조성물, 이의 제조방법 및 이를 포함하는 성형품에 관한 것으로, 보다 상세하게는 (A) 폴리에스테르 수지; (B) 비닐시안 화합물-공액디엔 화합물-방향족 비닐 화합물 그라프트 공중합체; (C) 알파-메틸스티렌-비닐시안 화합물 공중합체; (D) 말레이미드계 중합체; 및 (E) 아미드계 활제를 포함하는 것을 특징으로 하는 열가소성 수지 조성물, 이의 제조방법 및 이를 포함하는 성형품에 관한 것이다. 본 발명에 따르면, 종래의 내열 ABS 수지 조성물 대비 기계적 물성이 동등 이상으로 유지되면서도 내열성, 내화학성, 내광성 및 내소음성이 모두 뛰어나고, 특히, 경제성이 매우 우수하여 자동차 내장재로 적합한 열가소성 수지 조성물, 이의 제조방법 및 이를 포함하는 성형품을 제공하는 효과가 있다.
