Abstract

본 발명은 주요한 발포제로서의 물의 존재하에 특이 폴리이소시아네이트[여기서, 폴리이소시아네이트는 폴리메틸렌 폴리페닐 폴리이소시아네이트(중합체성 MDI)를 함유하는 폴리(옥시테트라메틸렌)글리콜(PTMG)을 사용하여 제조한 NCO-말단 예비중합체 또는 필수성분으로서 중합체성 MDI를 함유하는 유기 폴리이소시아네이트를 PTMG와 반응시켜 제조한 특이 NCO-말단 예비중합체의 특이 폴리이소시아네이트 혼합물을 포함한다]를 폴리올과 반응시켜 제조한 폴리우레탄 발포체 성형품에 관한 것이다. 폴리우레탄 발포체 성형품은 내마모성이 우수하고 자동차 핸들, 머리받아, 팔걸이 등으로서 유용할 수 있다.
