Abstract
(EN) The present invention provides a polyarylene sulfide copolymer, a production method thereof, and a molded article produced therefrom. The polyarylene sulfide copolymer includes a repeating unit in which at least a portion of the repeating unit of a polyarylene sulfide main chain includes a ketone group, and includes the repeating unit in a specific content range, thereby capable of enhancing impact resistance, heat resistance, and mechanical properties at the same time. Furthermore, the polyarylene sulfide copolymer can exhibit excellent physical properties optimized for each use through compounding with other polymeric materials or fillers, etc., and thus can be usefully applied to various fields.
(FR) La présente invention concerne un copolymère de poly(sulfure d'arylène), un procédé de production de celui-ci, et un article moulé produit à partir de celui-ci. Le copolymère de poly(sulfure d'arylène) comprend une unité répétitive dans laquelle au moins une portion de l'unité répétitive d'une chaîne principale de poly(sulfure d'arylène) comprend un groupe cétone, et comprend l'unité répétitive dans une plage de teneur spécifique, ainsi capable d'améliorer la résistance au choc, la résistance à la chaleur et les propriétés mécaniques en même temps. En outre, le copolymère de poly(sulfure d'arylène) peut présenter d'excellentes propriétés physiques optimisées pour chaque utilisation par mélange avec d'autres matériaux polymères ou charges, etc, et peut ainsi être utilement appliqué à divers domaines.
(KO) 본 발명은 폴리아릴렌 설파이드 공중합체, 이의 제조방법, 및 이로부터 제조된 성형품을 제공한다. 상기 폴리아릴렌 설파이드 공중합체는 폴리아릴렌 설파이드 주쇄의 반복 단위 중 적어도 일부가 케톤기를 포함하는 반복 단위를 포함하고, 이를 특정 함량 범위로 포함함으로써, 내충격성, 내열 특성 및 기계적 물성을 동시에 향상시킬 수 있다. 나아가, 상기 폴리아릴렌 설파이드 공중합체는 다른 고분자 소재 또는 충진재 등과의 컴파운딩을 통해, 각 용도에 최적화된 우수한 물성을 나타낼 수 있으므로, 다양한 분야에 유용하게 적용될 수 있다.
