Abstract

L'invention porte sur un matériau superabsorbant fait d'une combinaison (1) d'un superabsorbant cationique dans lequel 20 à 100 % des groupes fonctionnels se présentent sous forme de bases, et (2) d'un échangeur cationique dans lequel 5 à 100 % des groupes fonctionnels se présentent sous forme d'acides. Ladite combinaison s'avère particulièrement efficace comme superabsorbant de solutions contenant un électrolyte telles que le flux menstruel et l'urine.
