Abstract

PROCEDIMIENTO PARA LA OBTENCION DE POLIETERPOLIOLES CON UNA FUNCIONALIDAD HIDROXILO MEDIA DE COMO MINIMO 3 Y UN INDICE HIDROXILO DE 28 HASTA 1.000. CONSISTE EN LA ALCOXILACION DE UNA MEZCLA INICIADORA DE SACAROSA, DE UN POLIOL DE BAJO PESO MOLECULAR Y, EN CASO DADO, AGUA. COMO MATERIAL INICIADOR SE EMPLEA UNA MEZCLA FORMADA POR UN 20 A UN 80 POR 100 EN PESO DE SACAROSA Y UN 80 HASTA UN 20 POR 100 EN PESO DE FORMITA, CON UNA FUNCIONALIDAD HIDROXILO MEDIA DE COMO MINIMO 3. EL MATERIAL INICIADOR CONTIENE ADICIONALMENTE AGUA EN UNA CANTIDAD DE UN 0,5 HASTA UN 3 POR 100 EN PESO, REFERIDO A LA CANTIDAD TOTAL DE SACAROSA Y FORMITA. DE USO COMO PRODUCTOS DE PARTIDA PARA LA OBTENCION DE MATERIALES ESPUMADOS DE POLIURETANO, DUROS, RIGIDOS Y DE CELULAS CERRADAS.
