Abstract

PROCEDIMIENTO PARA LA ESTABILIZACION AL CALOR DE RESINAS HALOGENO-VINILICAS.COMPRENDE LAS SIGUIENTES FASES: PRIMERA, SE COMBINA POLVO DE RESINA CON UN MERCAPTOESTER DE POLIOL, RESULTANTE DE LA ESTERIFICACION DE SOLO UNA PARTE DE LOS HIDROXILOS DEL POLIOL MEDIANTE UN MERCAPTOACIDO; SEGUNDA, LA MEZCLA FORMADA SE HOMOGENEIZA Y SE FUNDE POR CALENTAMIENTO A UNA TEMPERATURA COMPRENDIDA ENTRE 150 Y 200 GRADOS; Y POR ULTIMO, SE MALAXA EL CALDO DURANTE UN TIEMPO DE APROXIMADAMENTE 5 MINUTOS Y A CONTINUACION SE CONFORMA Y ENFRIA.
