Abstract

L'invention concerne une matière superabsorbante comprenant une combinaison de (1) un superabsorbant anionique dans lequel 20 à 100 % des groupes fonctionnels se trouvent sous forme d'acide libre, et (2) un superabsorbant cationique dans lequel 20 à 100 % des groupes fonctionnels sont sous forme basique, le superabsorbant cationique se composant d'un polysaccharide ou d'un polymère d'unités d'un monomère de la formule (I), dans laquelle R1 et R2 peuvent être identiques ou différents, représentent chacun des radicaux organiques n'affectant pas négativement les propriétés du polymère, et X représente un anion approprié. La combinaison est particulièrement efficace en tant que superabsorbant dans le cas de solutions contenant un électrolyte telles que des menstrues et de l'urine.
