Abstract
본 발명은 결정성이 우수한 폴리에스테르 마스터뱃치의 제조방법에 관한 것으로, 폴리에틸렌테레프탈레이트(PET) 또는 이들의 공중합체에 벤젠-1,2,4,5-테트라 카르복실산 무수물을 결정화 핵체로 첨가함으로써 결정화 온도와 결정화 속도를 상승시켜 사출성형시 성형주기 감소와 성형온도 저하에 의한 성형성 향상과 성형물의 역학적 성질 즉, 굴곡 탄성율, 굴곡강도, 하중하에서의 변형온도 및 인장강도등의 우수한 폴리에스테르 마스터뱃치의 제조방법에 관한 것이다.The present invention relates to a method for producing a polyester masterbatch excellent in crystallinity, wherein benzene-1,2,4,5-tetra carboxylic anhydride is added to polyethylene terephthalate (PET) or a copolymer thereof as a crystallization nucleus. By increasing the crystallization temperature and the crystallization rate, it is possible to reduce the molding cycle during injection molding, improve the moldability by lowering the molding temperature, and the mechanical properties of the molding, that is, the excellent polyester master such as flexural modulus, flexural strength, deformation temperature under load and tensile strength. A method of making a batch.
