본 발명은 폴리에스테르계 수지 조성물 및 이의 성형품에 관한 것으로, 보다 상세하게는 폴리부틸렌 테레프탈레이트 수지 93 내지 99.5 중량%; 극성기 함유 활제 0.1 내지 3 중량%; 및 산화방지제 0.1 내지 2 중량%를 포함하는 것을 특징으로 하는 폴리에스테르계 수지 조성물 및 이의 성형품에 관한 것이다. 본 발명에 따르면, 유동성, 기계적 물성, 열안정성 및 사출 안정성이 우수하고, 표면 특성이 우수하여 난반사로 인한 무지개 빛이 발생하지 않으며 헤이즈가 낮아 자동차 헤드 램프 베젤에 특히 적합한 폴리에스테르계 수지 조성물 및 이의 성형품을 제공하는 효과가 있다.

    The present invention relates to a polyester-based resin composition and a molded article manufactured using the same. More particularly, the present invention relates to a polyester-based resin composition including 93 to 99.5 % by weight of a polybutylene terephthalate resin; 0.1 to 3 % by weight of a polar group-containing lubricant; and 0.1 to 2 % by weight of an antioxidant and a molded article manufactured using the polyester-based resin composition.According to the present invention, a polyester-based resin composition having excellent fluidity, mechanical properties, thermal stability, injection stability, and surface properties and a molded article manufactured using the same may be provided. In particular, due to excellent surface properties thereof, the polyester-based resin composition does not exhibit iridescence caused by diffuse reflection. In addition, the polyester-based resin composition has a low haze value. Accordingly, the polyester-based resin composition may be used to manufacture a molded article such as an automotive headlamp bezel.
