Abstract

SE PRESENTA UN GEL DE POLIMERO ESTIRENICO CAPAZ DE FORMAR ESPUMA QUE CONTIENE UN AGENTE SOPLADOR ACUOSO CAPAZ DE FORMAR UNA ESTRUCTURA DE ESPUMA UNIMODAL, DE CELULAS CERRADAS. EL GEL CONTIENE UNA MEZCLA DE LA MASA FUNDIDA CAPAZ DE FLUIR DE UNA COMPOSICION POLIMERICA QUE CONTIENE MAS DE UN 50 POR CIENTO EN PESO DE UN POLIMERO ESTIRENICO Y DE UN AGENTE SOPLADOR QUE TIENE UN 1 POR CIENTO O MAS EN PESO DE AGUA EN BASE AL PESO TOTAL DEL AGENTE SOPLADOR. EL POLIMERO ESTIRENICO TIENE UN GRADO DE SOLUBILIDAD EN AGUA SUFICIENTE COMO PARA ASEGURAR LA FORMACION DE UNA ESTRUCTURA DE ESPUMA UNIMODAL EN LUGAR DE UNA ESTRUCTURA DE ESPUMA BIMODAL. LA DISTRIBUCION DIMENSIONAL UNIMODAL DE LAS CELULAS OTORGA UNAS CARACTERISTICAS DE LABRABILIDAD Y MAQUINADO DESEABLES A LA ESTRUCTURA DE ESPUMA.
