Abstract

Se describe una composición para purificación de agua que comprende: (i) un polímero "A"; y (ii) un polímero aniónico B que tiene un peso molecular promedio en peso de al menos 0.5 millones de Daltons seleccionado de polisacáridos, poli(met)acrilatos, proteínas, celulosa modificada y poliacrilamida; donde dicho polímero "A" comprende unidades repetitivas a y ß en las cuales, "a" es H2C=C(R1)-C(O)O-(CH2)n-N+(R2)(R3)-(CH2)p-X donde -R1 representa un átomo de hidrógeno o un grupo alquilo C1 a C6 lineal o ramificado; -R2 y R3, independientemente uno del otro, representan un grupo alquilo, hidroxialquilo o aminoalquilo en el que el grupo alquilo es un alquilo C1 a C6 lineal o ramificado; - n = 1 a 4; -p = 2 a 8; -X representa un grupo funcional cargado negativamente seleccionado de carboxilato, sulfonato, sulfato o fosfato, y donde "ß" es H2C=C(R1)-C(O)O-(CH2)n-N(R2)(R3) en el que R1, R2, R3, n y p tienen el mismo significado que el asignado en referencia a las unidades repetitivas "a".
