Abstract
LA INVENCION TRATA DE UN PROCEDIMIENTO PARA PRODUCIR CONDENSADOS Y PRODUCTOS DE ADICION SOLUBLES EN AGUA Y QUE CONTIENEN GRUPOS AMINOS, QUE POSEEN UNAS BUENAS PROPIEDADES DE DESHIDRATACION Y RETENCION EN LA FABRICACION DEL PAPEL. ENTRE UN 5 Y UN 95 % EN PESO DE LOS CONDENSADOS O PRODUCTOS DE ADICION ES SEPARADO COMO PRODUCTO PERMEABLE DE UNAS SOLUCIONES DE CONDENSADOS O PRODUCTOS DE ADICION SOLUBLES EN AGUA Y QUE CONTIENEN GRUPOS AMINOS MEDIANTE SU ULTRAFILTRACION A TRAVES DE UNAS MEMBRANAS, PUDIENDO SER AISLADOS DEL PRODUCTO DE RETENCION LOS CONDENSADOS O PRODUCTOS DE ADICION QUE CONTIENEN GRUPOS AMINOS, QUE MUESTRAN UNA MEJOR EFICACIA. LOS COMPONENTES POLIMEROS DE ELEVADO PESO MOLECULAR CONTENIDOS EN EL PRODUCTO DE RETENCION, SON UTILIZADOS COMO MEDIOS DE RETENCION, DESHIDRATACION Y FIJACION EN LA FABRICACION DE PAPEL, COMO PROMOTORES EN EL ENCOLADO DEL PAPEL CON ALQUILDICETONAS, COMO MEDIOS DE FLOCULACION PARA LODOS DE CLARIFICACION, COMO ADHESIVOS EN LA FABRICACION DE PELICULAS COMPUESTAS, COMO ADITIVOS EN PRODUCTOS PARA EL CUIDADO DE LA PIEL Y EL CABELLO Y COMO MEDIOS PARA LA INMOBILIZACION DE SUSTANCIAS ACTIVAS ANIONICAS.
