Abstract

PROCESO PARA LA ALCOHOLIZACION DE UNA ESPUMA DE POLIURETANO FLEXIBLE MEDIANTE LA REACCION CON UN POLIOL ALCOHOLIZANTE, SEGUIDA POR LA SEPARACION Y RECOGIDA DE LA FASE SUPERIOR E INFERIOR. LA FASE SUPERIOR SE PUEDE SOMETER A EXTRACCION SEGUIDA DE ELIMINACION DEL AGENTE DE EXTRACCION; LOS POLIOLES ASI OBTENIDOS PUEDEN UTILIZARSE PARA PREPARAR POLIMEROS Y ESPUMAS FLEXIBLES. LA FASE INFERIOR PUEDE UTILIZARSE TRAS SU ALCOXILACION EN LA PREPARACION DE ESPUMAS RIGIDAS.
