Abstract

SE PREPARAN ELASTOMEROS DE POLIURETANO, QUE PRESENTAN UNA RESISTENCIA ANTES DE LA COCHURA MEJORADA, MANTENIENDO SIMULTANEAMENTE TIEMPOS DE DESMOLDEO CORTOS, A PARTIR DE POLIOLES DE POLIOXIPROPILENO CON UN GRADO DE INSATURACION ULTRABAJO, LOS CUALES CONTIENEN HASTA UN 20 PORCIENTO EN PESO DE FRACCIONES INTERNAS DE OXIETILENO ALEATORIAS. DICHOS ELASTOMEROS, ABSORBEN MENOS DEL 10 PORCIENTO EN PESO DE AGUA A 0 (GRADOS) C. DICHOS POLIOLES DE POLIOXIPROPILENO QUE CONTIENEN UNA FRACCION INTERNA DE POLIOXIETILENO, PUEDEN UTILIZARSE PARA PREPARAR POLIOLES CON EXTREMIDAD PROTEGIDA POR POLIOXIETILENO, CON GRADO DE INSATURACION ULTRABAJO, LOS CUALES CARECEN DE TURBIDEZ Y PUEDEN UTILIZARSE PARA PREPARAR PRECURSORES POLIMERICOS 4,4'' ES DE TURBIDEZ. SE PUEDEN CONSEGUIR MEJORAS AUN MAYORES EN LA FABRICACION DE LOS ELASTOMEROS, UTILIZANDO MEZCLAS MULTIDISPERSAS DE POLIOLES DE POLIOXIPROPILENO DE GRADO DE SATURACION ULTRABAJO, QUE CONTENGAN UNA FRACCION INTERNA DE OXIETILENO MONODISPERSA.
