Abstract

PROCEDIMIENTO PARA POLIMERIZAR UNA MEZCLA DE ISOMEROS DE METILESTIRENO EN LA QUE ES PREDOMINANTE EL ISOMERO PARA.CONSISTE EN MEZCLAR SUSTANCIALMENTE TODA LA MEZCLA DE ISOMEROS DE METILESTIRENO QUE HA DE POLIMERIZARSE CON INICIADORES DE POLIMERIZACION, INCLUYENDO UN INICIADOR DE ALTA TEMPERATURA Y UN INICIADOR DE BAJA TEMPERATURA. LA MEZCLA FORMADA SE HACE REACCIONAR A UNA TEMPERATURA ADECUADA PARA EFECTUAR LA POLIMERIZACION, OBTENIENDOSE UN POLI(METILESTIRENO) QUE TIENE UNA DISTRIBUCION DE PESOS MOLECULARES DE AL MENOS 4,0 Y UN INDICE DE FUSION DE AL MENOS 5,0.
