Abstract
테레프탈산을 주된 산성분으로 하고 에틸렌 글리콜을 주된 알콜 성분으로 하여 에스테르 교환 반응후 축중합 반응을 행하는 폴리에스테르 제조 방법에 있어서, 에스테르 교환 반응 종료후 축중합 반응 개시전 임의의 단계에 금속 화합물과 인화합물을 첨가하여 이어서 알루미노실리케이트를 에스테르 교환반응 생성물에 대하여 0.01∼0.1중량% 첨가하므로써 투명도와 이활성이 우수한 필름 성형용 폴리에스테르 제조방법.In a polyester production method wherein a polycondensation reaction is carried out after a transesterification reaction using terephthalic acid as a main acid component and ethylene glycol as a main alcohol component, a metal compound and a phosphorus compound are added at any stage before the start of the condensation polymerization reaction after the end of the transesterification reaction. A method for producing a polyester for film molding, which is excellent in transparency and activity by adding 0.01 to 0.1% by weight of aluminosilicate to the transesterification product.
