Abstract

구현예에 따르면, 종래와 유사한 방식으로 폴리티올을 제조하되 결과물에 잔류하는 티오우레아가 없도록 반응 조건을 조절함으로써, 보관안정성이 향상된 폴리티올을 용이하게 제조할 수 있다. 구체적으로, 반응에 사용되는 티오우레아의 당량을 특정 범위로 조절하여 미반응의 티오우레아의 양을 줄이고, 후공정으로 티오우레아를 한번 더 제거함으로써, 잔류 티오우레아를 효과적으로 제거하면서도 높은 수율을 달성할 수 있다. 이와 같이 제조된 폴리티올은 잔류 티오우레아를 함유하지 않아서 장기 보관 또는 고온 조건에서도 색상이 변하거나 침전물로 인한 백탁이 발생하지 않는다.
