Abstract

UN PROCEDIMIENTO 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 INTERNA DE LA PARED HA SIDO PREVIAMENTE RECUBIERTA CON UNA SOLUCION DE REVESTIMIENTO QUE CONTIENE (A) POR LO MENOS UN MIEMBRO SELECCIONADO ENTRE EL GRUPO FORMADO POR DETERMINADOS COLORANTES ANIONICOS Y SALES DE METALES ALCALINOS Y SALES AMONICAS DE UN PRODUCTO SULFONADO OBTENIDO POR SULFONACION DE UN DETERMINADO COMPUESTO AMINICO AROMATICO CON UN DETERMINADO COMPUESTO NITRO AROMATICO Y (B) UN DETERMINADO COLORANTE CATIONICO, Y CON UN PH SUPERIOR A 7, Y DESPUES HA SIDO SECADA PARA FORMAR UN REVESTIMIENTO. MEDIANTE ESTE METODO PUEDE IMPEDIRSE EFICAZMENTE LA FORMACION DE INCRUSTRACIONES EN LA POLIMERIZACION DE UN GRAN NUMERO DE MONOMEROS CON UN DOBLE ENLACE ETILENICO, DE MANERA QUE PUEDEN REPETIRSE 100 O MAS OPERACIONES DE POLIMERIZACION SIN FORMACION DE INCRUSTRACIONES POLIMERICAS.
