Abstract

본 발명은 디페닐메탄 이소시아네이트 기재의 이소시아네이트 말단 프리폴리머에 관한 것이다. 이 프리폴리머는 약 75내지 약 95중량%의 이핵 이성질체 및 약 5내지 약 25중량%의중합 이소시아네이트를 함유한 디페닐메탄 이소시아네이트 혼합물과 폴리에테르 폴리올과의 반응 산물이다. 이핵 이성질체는 일반적으로 약 15내지 약 40중량%의 2,4'-이성질체 약 2내지 약 10중량%의 2, 2'-이성질체를 함유하고 있다. 폴리에테르 폴리올은 약 3내지 약8의 관능가, 약 350내지 약 1000㎎수산화칼륨/g의 OH 수 및 약 150 내지 약 1000의 분자량을 가진다. 상기 프리폴리머는 특히 밝은 색 치수 안정성 경질 폴리우레탄 발포체의 생산을 위한 출발물질로서 유용하다.
