Abstract

EL INVENTO SE REFIERE A UN PROCEDIMIENTO PARA PRODUCIR COPOLIMERIZADOS QUE SON HINCHABLES POR AGUA, TIENEN FORMA DE GEL, SE PRESENTAN EN PARTICULAS IDENTICAS Y SE OBTIENEN MEDIANTE COPOLIMERIZACION DE 100 PARTES EN PESO DE MONOMEROS INSATURADOS MONOETILENIAS SOLUBLES EN AGUA, 0.01 A 5 PARTES EN PESO DE MONUMEROS CONTENIENDO DOS DOBLE ENLACES INSATURADOS ETILENICAMENTE Y 0 A 20 PARTES EN PESO DE MONOMEROS INSATURADOS INSATURADOS MONOETILICAMENTE INSOLUBLES EN AGUA, EN UN 20 A 80% EN PESO DE SOLUCION ACUOSA, EN PRESENCIA DE INICIADORES DE POLIMERIZACION Y DE 0,1 A 10% EN PESO CON RESPECTO A LOS MONOMEROS EMPLEADOS EN LA COPOLOMERIZACION EN TENSOACTIVOS. SE CARACTERIZA PORQUE LOS MONOMEROS SE APOLIMERIZAN EN PRESENCIA DE 0<50% EN TENSOACTIVO A LA MEZCLA DE REACCION; SE REALIZA TOTALMENTE LA COPOLIMERIZACION Y SE SACA LAS PARTICULAS GEL OBTENIDAS.
