A thermoplastic resin composition of the present invention comprises: (A) about 20 to about 70% by weight of an aromatic polyamide resin comprising at least two aromatic dicarboxylic acid units; (B) about 0.1 to about 20% by weight of an olefin-based copolymer; and (C) about 10% to about 60% by weight of an inorganic filler. The thermoplastic resin composition and a molded article produced therefrom are excellent in platability, impact resistance, heat resistance and the like. La présente invention concerne une composition de résine thermoplastique comprenant : (A) d'environ 20 à environ 70 % en poids d'une résine de polyamide aromatique comprenant au moins deux motifs d'acide dicarboxylique aromatique; (B) d'environ 0,1 à environ 20 % en poids d'un copolymère à base d'oléfine; et (C) d'environ 10 % à environ 60 % en poids d'une charge inorganique. La composition de résine thermoplastique et un article moulé produit à partir de cette dernière présentent une excellente aptitude au façonnage en tôle, résistance aux chocs, résistance à la chaleur et similaires. 본 발명의 열가소성 수지 조성물은 (A) 적어도 2종의 방향족 디카르복실산 단위를 포함하는 방향족 폴리아미드 수지 약 20 내지 약 70 중량%; (B) 올레핀계 공중합체 약 0.1 내지 약 20 중량%; 및 (C) 무기필러 약 10 내지 약 60 중량%를 포함하는 것을 특징으로 한다. 상기 열가소성 수지 조성물 및 이로부터 제조된 성형품은 도금성, 내충격성, 내열성 등이 우수하다.
