Abstract

PROCEDIMIENTO PARA LA OBTENCION DE COPOLIMERIZADOS QUE CONTIENEN ACIDOS MONOCARBOXILICOS Y DICARBOXILICOS CON UNA INSATURACION ETILENICA COMO MONOMEROS. CONSISTE EN LA COPOLIMERIZACION DE 10-60% DE UN ACIDO CARBOXILICO C <- CON UNA INSATURACION ETILENICA, 90-40% DE UN ACIDO MONOCARBOXILICO C <- CON UNA INSATURACION ETILENICA, Y 0-20% DE UN MONOMERO EXENTO DE GRUPOS CARBOXILO CON UNA INSATURACION ETILENICA, EN UN MEDIO ACUOSO, EN PRESENCIA DE 0,5-5% DE UN INICIADOR HIDROSOLUBLE. ESTOS COMPUESTOS TIENEN APLICACIONES COMO INHIBIDORES DE INCRUSTACION EN AGENTES DE LAVADO Y DETERGENTES.
