Abstract The present invention relates to a thermoplastic resin composition comprising: a first graft polymer including a first diene-based rubbery polymer grafted with a vinyl aromatic monomer unit and a vinyl cyanide-based monomer unit; a second graft polymer including a second diene-based rubbery polymer grafted with a vinyl aromatic monomer unit and a vinyl cyanide-based monomer unit; a vinyl-based polymer including a vinyl aromatic monomer unit and a vinyl cyanide monomer unit; an olefin-based polymer containing an olefin-based monomer unit and an acetate-based monomer unit and having a flow index of 20 to 30 g/10 min measured under the conditions of 220℃ and 10 kg according to ASTM D1238; and stearyl alcohol. Accordingly, the thermoplastic resin composition with improved processability, low-temperature whitening properties, low-temperature impact resistance, and post-shrinkage properties can be provided. 본 발명은 비닐 방향족계 단량체 단위 및 비닐 시아나이드계 단량체 단위가 그라프트된 제1 디엔계 고무질 중합체를 포함하는 제1 그라프트 중합체; 비닐 방향족계 단량체 단위 및 비닐 시아나이드계 단량체 단위가 그라프트된 제2 디엔계 고무질 중합체를 포함하는 제2 그라프트 중합체; 비닐 방향족계 단량체 단위 및 비닐 시아나이드계 단량체 단위를 포함하는 비닐계 중합체; ASTM D1238에 의거하여 220 ℃, 10 ㎏의 조건 하에서 측정한 유동지수가 20 내지 30 g/10 min이고, 올레핀계 단량체 단위 및 아세테이트계 단량체 단위를 포함하는 올레핀계 중합체; 및 스테아릴 알코올을 포함하는 열가소성 수지 조성물에 관한 것이다.
