Abstract: The invention relates to a method for the surface secondary cross-linking of water-absorbent polymers by treatment of the polymers with a solution for surface secondary cross-linking. According to said method the polymers during or after spraying are subjected to secondary cross-linking and dried by raising the temperature to 50-250 ~C and the cross-linking agent contains a boric acid ester with a bivalent or trivalent alcohol dissolved in an inert solvent. The invention also relates to water-absorbent polymers obtainable in accordance with the above method and to their use in hygiene articles, packing materials and non-woven materials.
