The present invention relates to a thermoplastic resin composition, a method of preparing the thermoplastic resin composition, and an injection molded product including the thermoplastic resin composition. More specifically, the present invention relates to the thermoplastic resin composition and the injection molded product including the same. The thermoplastic resin composition includes: a (meth)acrylic rubber-aromatic vinyl compound-vinyl cyanide compound copolymer having a graft ratio of 32 to 42% and an average particle diameter of 500 to 1,500 Å; a (meth)acrylic rubber polymer-aromatic vinyl compound-vinyl cyanide compound copolymer having a graft ratio of 32 to 45% and an average particle diameter of 2,000 to 3,000 Å; and an (alpha-alkylstyrene)-vinyl cyanide compound copolymer in specific contents, thereby obtaining excellent impact resistance, heat resistance, durability, weatherability and other properties, and improving deposition properties, glossiness, adhesion and other properties during the non-painting process such that the thermoplastic resin composition is capable of providing an injection molded product having excellent quality.

    본 발명은 열가소성 수지 조성물, 이의 제조방법 및 사출 성형품에 관한 것으로, 보다 상세하게는 그라프트율이 32 내지 42%인 평균입경 500 내지 1,500Å의 (메타)아크릴계 고무-방향족 비닐 화합물-비닐시안 화합물 공중합체; 그라프트율이 32 내지 45%인 평균입경 2,000 내지 3,000Å의 (메타)아크릴계 고무 중합체-방향족 비닐 화합물-비닐시안 화합물 공중합체; 및 (알파-알킬스티렌)-비닐시안 화합물 공중합체;를 특정 함량으로 포함하여 내충격성, 내열성, 내구성, 내후성 등이 뛰어나면서도 무도장 공정 시 증착성, 광택성, 밀착성 등이 향상되어 우수한 품질의 사출 성형품을 제공할 수 있는 열가소성 수지 조성물 및 사출 성형품에 관한 것이다.
