Abstract
La présente invention concerne un mélange polymère formant un hydrogel. Ce mélange comprend a) un polymère I formant un hydrogel, avec des restes acides, et b) un polymère II formant un hydrogel, avec des restes amino et/ou imino, le rapport des restes acides sur la somme des restes amino et/ou imino s'élevant de 1 : 9 à 9 : 1. Cette invention concerne également l'utilisation de ces mélanges dans des articles d'hygiène absorbants.
