Abstract

La presente invencion proporciona una material superabsorbente que comprende una combinacion de (1) un superabsorbente cationico, en el cual de 20% a ??100% de los grupos funcionales están en forma básica, y (2) un intercambiador cationico, en el cual de 50 a 100% de los grupos funcionales están en forma ácida. La combinacion es particularmente efectiva como un superabsorbente, para soluciones que contienen electrolitos, tal como menstruacion y orina.
