Abstract

PROCEDIMIENTO PARA LA REDUCCION DEL CONTENIDO DE MONOMEROS RESIDUALES EN DISPERSIONES ACUOSAS DE PLASTICO A BASE DE ESTERES DE POLIVINILO. PRODUCCION DE DISPERSIONES ACUOSAS DE PLASTICO QUE CONTIENEN POLIMERIZADOS DE ESTERES DE VINILO O COPOLIMERIZADOS DE ESTERES DE VINILO CON CONTENIDOS REDUCIDOS EN ESTERES VINILICOS NO DESEADOS, MONOMEROS RESIDUALES, CONDICIONADOS POR LA PRODUCCION, Y, DADO EL CASO, ALDEHIDO ACETICO DE LAS CORRESPONDIENTES DISPERSIONES INICIALES, COMO SE PUEDEN OBTENER SEGUN LOS METODOS CORRIENTES DE POLIMERIZACION O COPOLIMERIZACION A PARTIR DE MONOMEROS ETILENICOS NO SATURADOS, MEDIANTE SAPONIFICACION ALCALINA SELECTIVA DE LOS ESTERES DE VINILOS MONOMEROS RESIDUALES SAPONIFICABLES ALCALINOS, Y, DADO EL CASO, OXIDACION DEL ALDEHIDO ACETICO EN ACIDO ACETICO EN LAS DISPERSIONES ACUOSAS. UTILIZACION DE LAS DISPERSIONES DE PLASTICO COMO LIGANTE EN PREPARADOS ACUOSOS POBRES EN EMISIONES O LIBRES DE EMISIONES, COMO POR EJEMPLO PARA PINTURAS, REVESTIMIENTOS, MORTERO DE CALADO,PEGAMENTOS, AGENTES DE ENCOLADO DE PAPEL, LIGANTES DE FIBRAS DE VELLON, MEDIOS AUXILIARES TEXTILES, ETC., ESPECIALMENTE PARA APLICACIONES EN LOCALES INTERIORES O EN LOCALES CERRADOS.
