Title (EN) MICROCELLULAR POLYURETHANE POLYMERS PREPARED FROM ISOCYANATE-TERMINATED POLY(OXYTETRAMETHYLENE) GLYCOL PREPOLYMERS
(FR) POLYMERES MICROCELLULAIRES DE POLYURETHANE PREPARES A PARTIR DE PREPOLYMERES DE POLY(OXYTETRAMETHYLENE) GLYCOL A TERMINAISON ISOCYANATE
Abstract:
(EN) 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.
(FR) Procédé de préparation de polymères microcellulaires de polyuréthane à l'aide d'une réaction entre une composition organique de polyisocyanate comportant un prépolymère de poly(oxytétraméthylène) glycol à terminaison isocyanate, et une composition active renfermant de l'hydrogène et comportant un polyol de polyéther et un agent extendeur de chaîne, en présence d'un agent porogène à teneur en eau. Les polymères ainsi obtenus présentent de bonnes propriétés physiques telles qu'une résistance au frottement et la durabilité, et son utiles pour les semelles de chaussures et pour l'industrie de l'automobile.
