수성 폴리우레탄 분산액은 인조 가죽 및 유사한 제품을 제조하는 데 유용하다. 분산액은 수성상 중에 분산된 폴리우레탄-우레아 입자를 함유한다. 입자는 아이소포론 다이아이소시아네이트, 소정의 환형 아민 사슬 연장제 및 소정의 폴리올 혼합물을 사용하여 제조된다. Aqueous polyurethane dispersions are useful for making artificial leather and similar products. The dispersions contain polyurethane-urea particles dispersed in an aqueous phase. The particles are made using isophorone diisocyanate, certain cyclic amine chain extenders and certain polyol mixtures.
