Abstract

L'invention concerne un procédé pour la post-réticulation en surface de polymères hydroabsorbants, dans lequel le polymère est aspergé d'une solution permettant la post-réticulation en surface. Comme agent de réticulation, cette solution contient des esters phosphoriques de la formule (1) ou (2), où X représente OH ou NH¿2?, et R représente alkylène C¿1?-C¿12?, ou encore un mélange de ces esters dissous dans un solvant inerte. Pendant ou après l'aspersion, le produit humecté subit une post-réticulation et est séché par élévation de la température à une valeur comprise entre 50 et 250 ·C. L'invention concerne des polymères hydroabsorbants obtenus selon le procédé précité, ainsi que leur utilisation dans des produits d'hygiène, des matériaux d'emballage et des non-tissés.
