Abstract

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