摘要：This invention relates to a process for preparing microcellular polyurethane polymers by reaction of an organic polyisocyanate composition comprising an isocyanate-terminated poly(oxytetramethylene) glycol prepolymer with an active hydrogen-containing composition which comprises a polyesther polyol and a chain-extending agent, in the presence of a blowing agent comprising water. Resulting polymers display good physical properties including abrasion resistance and durability and are of value in shoe soles applications and automotive applications.
