Abstract

SE PRESENTA UNA ESTRUCTURA DE ESPUMA DE POLIMERO ETILENICO QUE COMPRENDE UN MATERIAL DE POLIMERO ETILENICO. EL MATERIAL DE POLIMERO ETILENICO CONTIENE UN POLIMERO ETILENICO SUBSTANCIALMENTE LINEAL QUE TIENE (A) UNA RELACION DE FLUJO EN ESTADO FUNDIDO 1{SUB, 10}/L{SUB, 2}> = 5.63; (B) UNA DISTRIBUCION DE PESO MOLECULAR M{SUB, W}/M{SUB, N}, DEFINIDA POR LA ECUACION M{SUB, W}/M{SUB, M} <= (L{SUB, 10}/L{SUB, 2})-4.63; Y (C) UNA PROPORCION CRITICA DE CORTE EN LA DISPOSICION DE UNA FRACTURA SUPERFICIAL EN ESTADO FUNDIDO DE AL MENOS UN 50% MAYOR QUE LA PROPORCION CRITICA DE CORTE EN LA DISPOSICION DE UNA FRACTURA SUPERFICIAL EN ESTADO FUNDIDO DE UN POLIMERO DE OLEFINA LINEAL QUE TENGA ALREDEDOR DEL MISMO L{SUB, 2} Y M{SUB, W}/M{SUB, N}. LAS ESTRUCTURAS DE ESPUMA TIENE UN TACTO Y UNA ELASTICIDAD SIMILAR A AQUELLAS FORMADAS A PARTIR DE LLDPE CONVENCIONAL SIN LA POBRE ESTABILIDAD DIMENSIONAL Y UNA CALIDAD DE ESPUMA ASOCIADA CON LA DE AQUELLAS ESTRUCTURAS. LAS ESTRUCTURAS DE ESPUMA TIENEN UNA CALIDADDE ESPUMA SIMILAR A AQUELLAS HECHAS CON LDPE CONVENCIONAL PERO CON UNA ELASTICIDAD MEJORADA. ADEMAS SE PRESENTA UN PROCESO PARA LLEVAR A CABO LA ESTRUCTURA DE ESPUMA MENCIONADA Y PARA REALIZARLA EN FORMA DE GOTAS DE ESPUMA. ADEMAS SE PRESENTA UN PROCESO PARA FABRICAR UN ARTICULO A PARTIR DE LAS GOTAS DE ESPUMA.
