Abstract
본 발명은 저중합촉매량, 저중합온도라고 하는 온화한 조건하에 있어서도, 효율좋게 포리락트산을 제조할 수 있는 방법을 제공하는 것을 과제로 하며, 그 해결수단으로서, 락티드, 고리상이미드화합물(예를들면 숙신이 미드) 및 중합촉매(예을들면 옥틸산주석)를, N2기류하, 100∼190℃로 가열교반해서, 중합반응을 행한다. 고리상이미드 화합물의 양은, 락티드에 대해서 1∼35mol%가 바람직하다. 중합촉매가 락티드에 대해서 0.00001∼0.1mol%로 적은 양이라고, 효율좋게 폴리락트산을 제조할 수 있다. 그리하여, 폴리머속으로의 촉매의 잔류와 폴리머의 착색을 피할수 있다.
