A surface cross-linked superabsorbent polymer composition, a process for its preparation and articles made therefrom wherein said superabsorbent composition is prepared by surface cross-linking the polymerization product of a carboxyl or carboxylate group containing monomer with a cross-linker solution comprising water, C3-C6 diol and a cross-linking compound having at least two functional reactive groups with the carboxyl or carboxylate groups of said polymerization product.
On décrit une composition d'un polymère super-absorbant réticulé en surface, un procédé concernant sa préparation, et des articles fabriqués à partir de cette composition, laquelle s'obtient par réticulation en surface d'un produit de polymérisation d'un carboxyle, ou d'un groupe carboxylate contenant un monomère, avec une solution de réticulation comprenant de l'eau, C¿3?-C¿6? diol et un composé de réticulation doté d'au moins deux groupes fonctionnels pouvant réagir avec le carboxyle ou le groupe carboxylate dudit produit de polymérisation.
