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.

Abstract: A flexible absorbent sheet material containing an acidic water-absorbing resin, a basic water-absorbing resin, and a plasticizer, and its method of manufacture, are disclosed. The sheets contain about 60% to 100% by weight of the acidic and basic water-absorbent resin and plasticizer. The absorbent sheets have unexpected flexibility and structural integrity, while exhibiting exceptional water absorption and retention properties.
