Abstract
UN METODO DE PREVENCION DE LA FORMACION DE INCRUSTACIONES POLIMERICAS EN UNA VASIJA DE POLIMERIZACION DURANTE LA POLIMERIZACION DE UN MONOMERO CON UN DOBLE ENLACE ETILENICO, DONDE LA CITADA POLIMERIZACION SE REALIZA EN UNA VASIJA DE POLIMERIZACION CUYA SUPERFICIE DE LA PARED INTERNA HA SIDO PREVIAMENTE RECUBIERTA CON UNA SOLUCION DE REVESTIMIENTO DE BASE ACUOSA QUE CONTIENE (A) UN COLORANTE ANIONICO SOLUBLE EN AGUA Y (B) POR LO MENOS UN MIEMBRO SELECCIONADO ENTRE EL GRUPO FORMADO POR COLORANTES CATIONICOS INSOLUBLES EN AGUA Y COMPUESTOS ORGANICOS NITROGENADOS INSOLUBLES EN AGUA Y CON UN PH DE 7 O MENOS Y DESPUES SE SECA PARA FORMAR UNA REVESTIMIENTO. ESTE METODO PUEDE EVITAR EFICAZMENTE LA FORMACION DE INCRUSTACIONES EN LA POLIMERIZACION DE NUMEROSOS MONOMEROS CON UN DOBLE ENLACE ETILENICO.
