Abstract

POLIMERIZADO DE ESTIROL EXPANDIBLE EN FORMA DE PERLA SE OBTIENE A TRAVES DE LA POLIMERIZACION DE LA SUSPENSION DE ESTIROL CON ADICION DE 1 A 10% EN PESO DE HIDROCARBUROS DE C3 A 7 Y/O DIOXIDO DE CARBONO COMO INICIADORES Y ADITIVOS USUALES. COMO ESTABILIZADOR DE SUSPENSION SE EMPLEA UNA MEZCLA DE EXTENDEDOR CONTENIENDO UN GRUPO SULFONATO, PIROFOSFATO DE MAGNESIO Y UN CARBOXILATO ALCALINO O ALCALINOTERREO. EL PIROFOSFATO DE MAGNESIO SE OBTIENE INMEDIATAMENTE ANTES DE LA POLIMERIZACION A TRAVES DE LA COMBINACION DE UNA SOLUCION ACUOSA DE UN PIROFOSFATO ALCALINO CON POR LO MENOS LA CANTIDAD ESTEQUIOMETRICA NECESARIA DE UNA SAL DE MAGNESIO.
