- 테레프탈산 또는 이를 주성분으로하는 디카르복실산 및 그 유도체와 에틸렌글리콜 또는 이를 주성분으로하는 글리콜 및 그 유도체를 직접에스테르화 반응시키거나, 또는 디메틸테레프탈레이트 또는 이를 주성분으로하는 디알킬테레프탈레이트 또는 이들의 이성질체 혹은 유도체와 에틸렌글리콜 또는 이를 주성분으로 하는 글리콜 및 그 유도체를 에스테르교환반응시켜 비스(베타-히드록시에틸)테레프탈레이트 및/또는 이의 저분자량 축합물(중합도 2-10)이 주성분이 된 에스테르화물을 얻고 연속해서 이를 중축합 촉매의 존재하에 중축합시켜 폴리에스테르를 제조함에 있어서, 직접에스테르화반응 혹은 에스테르교환반응의 개시 직전 혹은 반응종료 직후에 부분에스테르화 트리멜리트산염을 최종 중합체 내에 금속함량이 0.002∼2중량%가 되도록 첨가하는 것을 특징으로 하는 폴리에스테르 중합체의 제조방법.
- 제1항에 있어서, 상기 부분에스테르화 트리멜리트산염이 다음으로부터 선택되는 화합물 단독 또는 이들의 혼합물인 것을 특징으로 하는 폴리에스테르 중합체의 제조방법: ㈀ 트리멜리트산과 알코올로부터 부분에스테르화하거나 또는 트리멜리트산무수물과 알코올로부터 무수물기의 개환반응에 의해 부분 에스테르화하여 얻은 주성분이 부분에스테르화 트리멜르트산인 반응혼합물을 연속해서 트리멜리트산 또는 트리멜리트산 무수물 1몰에 대하여 알칼리금속수산염 0.9∼2.1몰 또는 알칼리금속 탄산염 0.45∼1.05몰과 반응시켜 얻은 부분에스테르화 트리멜리트산염, 및 ㈁ 상기 ㈀의 부분에스테르화 트리멜리트산염을 트리멜리트산 또는 트리멜리트산 무수물 1몰에 대하여 알칼리토류금속 할라이드 또는 전이금속할라이드 0.45∼1.05몰과 한번 더 반응시켜 얻은 부분에스테르화 트리멜리트산염.
- 제2항에 있어서, 상기 부분에스테르화 트리멜리트산염이 따로 분리해내지 않고 반응혼합물 그대로 첨가되거나 또는 건조분말을 에틸렌글리콜에 분산시킨 슬러리 또는 용해시킨 용액으로 첨가되는 것을 특징으로 하는 폴리에스테르 중합체의 제조방법.
- 제2항에 있어서, 상기 알코올이 탄소수 1∼18개의 알킬기를 갖는 알코올 또는 탄소수 2∼18개의 알킬렌기를 갖는 알킬렌글리콜인 것을 특징으로 하는 폴리에스테르 중합체의 제조방법.
- 제4항에 있어서, 상기 알코올이 메틸알코올 또는 에틸렌글리콜인 것을 특징으로 하는 폴리에스테르 중합체의 제조방법.
