Abstract

AGENTE ESTABILIZADOR PARA POLIMERIZACION EN SUSPENSION Y PROCEDIMIENTO DE POLIMERIZACION EN SUSPENSION. SE EFECTUA LA POLIMERIZACION AÑADIENDO A MONOMEROS DE CLORURO DE VINILO UN 0,01-0,3 POR 100 EN PESO DE UN AGENTE ESTABILIZADOR, QUE COMPRENDE: UN POLI(ALCOHOL VINILICO) MODIFICADO Y PARCIALMENTE HIDROLIZADO, Y OPCIONALMENTE ALGUN DERIVADO DE CELULOSA Y/O COPOLIMERO EN BLOQUE DE OXIDO DE PROPILENO Y OXIDO DE ETILENO. EL AGENTE TIENE GRUPOS HIDROFILOS ANIONICOS EN SUS CADENAS LATERALES, UN GRADO DE POLIMERIZACION DE 200-3.000 Y UN GRADO DE HIDROLISIS DE 60-90 POR 100. SE USAN PEROXIDOS ORGANICOS, PEROXIDICARBONATOS DE DI-ALCOHILO, COMPUESTOS AZOICOS, ETC., COMO INICIADORES DE POLIMERIZACION Y, OPCIONALMENTE, HIDROCARBUROS SATURADOS COMO AGENTES DE TRANSFERENCIA DE CADENA. SE MANTIENE LA MEZCLA A TEMPERATURA DE 30-75GC DURANTE 5-17 HORAS. DE APLICACION EN LA FABRICACION DE RESINAS RIGIDAS O FLEXIBLES DE POLI(CLORURO DE VINILO) Y PROCEDIMIENTOS DE POLIMERIZACION EN SUSPENSION EN GENERAL. G
