The present invention provides a superabsorbent material which comprises a combination of (1) an anionic superabsorbent in which from 20 to 100 % of the functional groups are in free acid form, and (2) an anion exchanger in which from 20 to 100 % of the functional groups are in basic form. The combination is particularly effective as a superabsorbent in the case of electrolyte containing solutions such as menses and urine.
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.
