Abstract
PROCEDIMIENTO Y DISPOSITIVO PARA LA OBTENCION DE POLIMEROS DE CLORURO DE VINILO. CONSISTE EN POLIMERIZAR EL MONOMERO O LA MEZCLA DE MONOMERO EN DISPERSION ACUOSA CON CATALIZADORES FORMADORES DE RADICALES. OPCIONALMENTE PUEDEN EMPLEARSE AGENTES ESTABILIZADORES DE SUSPENSION, EMULSIONANTES Y OTRAS SUSTANCIAS AUXILIARES DE POLIMERIZACION. EL REACTOR TIENE LAS PAREDES EN QUE PUEDEN FORMARSE SEDIMENTOS CUBIERTOS TOTAL O PARCIALMENTE CON UNA SUSTANCIA DE FORMULA GENERAL (I). LAS SUPERFICIES RECUBIERTAS SON LAVADAS CON AGUA ANTES DE LA POLIMERIZACION. +FORMULA*
