Abstract

PROCEDIMIENTO PARA LA FABRICACION DE UN PRODUCTO DESTINADO A PREVENIR LA DEPOSICION DE INCRUSTACIONES DE POLIMERO EN LA POLIMERIZACION DE MONOMEROS ETILENICAMENTE INSATURADOS EN UN MEDIO DE POLIMERIZACION ACUOSO. CONSISTE EN DISPONER, ANTES DE LA POLIMERIZACION, UNA CAPA DE REVESTIMIENTO SOBRE LA SUPERFICIE FORMADA DE UN PRODUCTO DE CONDENSACION, PREPARADO POR LA REACCION DE CONDENSACION DE POR LO MENOS UN COMPUESTO DE AMINA AROMATICA Y POR LO MENOS UN COMPUESTO NITRO AROMATICO, EN PRESENCIA DE UN ACIDO MINERAL Y UN CATALIZADOR DE CONDENSACION, A UNA TEMPERATURA COMPRENDIDA ENTRE 100 Y 250 GRADOS. LA AMINA AROMATICA SE SELECCIONA ENTRE ANILINA, 1,2-, 1,3- Y 1,4-FENILENODIAMINAS, 2-, 3- Y 4-AMINO-FENOLES, 4-AMINO-DIFENIL-AMINA Y 4,4 -DIAMINO-DIFENIL-AMINA.
