Abstract

L'invention porte sur un polysaccharide cationique, de préférence sous forme fibreuse, présentant des caractéristiques superabsorbantes, les polysaccharides étant substitués par des groupes ammonium quaternaires et présentant un ds (degré de substitution) d'au moins 0,5 et de préférence compris entre 0,5 et 2,5, et les polysaccharides étant suffisament réticulés pour rester insolubles dans l'eau. Le polysaccharide est de préférence de la cellulose. Le nombre accru des groupes fonctionnels du produit en améliore les proprités superabsorbantes, tandis que le recours à un agent de réticulation permet d'ajuster la résistance à l'état de gel du produit et d'en adapter plus facilement les caractéristiques à celles demandées.
