- 산성분의 90몰%가 테레프탈산인 2관능성 카르복실산과 알콜화합물의 90몰%가 에틸렌글리콜인 글리콜과의 직접 에스테르화법에 의한 폴리에스터 제조방법에 있어서, 촉매로서 하기 일반식(1)의 화합물 및 소듐테레프탈레이트 폴리에스터를 전산성분에 대하여 각각 0.01 내지 0.1몰% 및 0.005 내지 0.07몰% 첨가하여 에스테르반응을 수행하고, 에스테르화 반응이 실질적으로 완료한 시점으로부터 중축합이 종료하기 이전의 단계에서 코발트 화합물과 인화합물의 착화합물을 폴리에스터에 대하여 코발트 원자로 10 내지 50ppm 첨가하는 것을 특징으로 하는 폴리에스터의 제조방법.(상기 식에서, R은 탄소수가 1~8인 직쇄 또는 분지상의 알킬기, 시클로헥실, 4-부틸페닐기로 구성되는 군으로부터 선택될 수 있고, R'는 수산기, 탄소수가 1~8인 직쇄 또는 분지상의 알킬기, 시클로헥실, 4-부틸페닐기로 구성되는 군으로부터 선택될 수 있다.)
- 제1항에 있어서, 인화합물과 코발트화합물의 착화합물은 에틸렌글리콜중에서 트리알킬포스페이트와 에틸렌글리콜 용해 가능한 코발트 화합물을 120 내지 170oC로 가열하여 5 내지 30분간 반응시키되, 트리알킬포스페이트 1몰에 대하여 코발트 화합물 0.2 내지 0.8몰의 비로 제조하는 것을 특징으로 하는 폴리에스터의 제조방법.
