Beschreibung
Zusammenfassung:	The present invention relates to a thermoplastic resin composition which comprises: a graft copolymer comprising a diene-based rubbery polymer to which a vinyl cyanide-based monomer unit and a vinyl aromatic-based monomer unit are grafted; a first copolymer comprising a maleimide-based monomer unit and the vinyl aromatic-based monomer unit; a second copolymer comprising the vinyl cyanide-based monomer unit and the vinyl aromatic-based monomer unit; magnesium oxide, wherein the second copolymer comprises 27 to 35 wt% of the vinyl cyanide-based monomer unit and has a weight average molecular weight of 80,000 to 110,000 g/mol. 본 발명은 비닐 시아나이드계 단량체 단위 및 비닐 방향족계 단량체 단위가 그라프트된 디엔계 고무질 중합체를 포함하는 그라프트 공중합체; 말레이미드계 단량체 단위 및 비닐 방향족계 단량체 단위를 포함하는 제1 공중합체; 비닐 시아나이드계 단량체 단위 및 비닐 방향족계 단량체 단위를 포함하는 제2 공중합체; 및 산화마그네슘을 포함하고, 상기 제2 공중합체는 상기 비닐 시아나이드계 단량체 단위를 27 내지 35 중량%로 포함하고, 중량평균분자량이 80,000 내지 110,000 g/mol인 열가소성 수지 조성물에 관한 것이다.
