Abstract: Liquid-absorbent polymers are prepared by a process for the gel and/or surface postcrosslinking of water-absorbent polymers by the polymer being treated with a surface postcrosslinking solution and being postcrosslinked and dried during and after the treatment by raising the temperature, wherein the crosslinker comprises a compound of the formula Iwhere R is hydrogen, C1-C4-alkyl, C1-C4-hydroxyalkyl, trialkylsilyl or acetyl and R , R , R , R , R , R are each independently hydrogen, C1-C12-alkyl, C2-C12-alkenyl or C6-C12-aryl, dissolved in an inert solvent, and are used in hygiene articles, packaging materials and nonwovens.

Abstract: The invention relates to a cross-linked, water-swellable polymer that contains polymerized into it moieties of a) water-soluble, monoethylenically unsaturated monomers, and b) 0.001 to 5 mole % based on the monomers a) of a cross-linking combination, b1) a first cross-linking agent with at least two (meth)acrylic ester moieties in the molecule and b2) a second cross-linking agent with at least two (meth)allyloxy moieties in the molecule, the molar ratio of b1) to b2) ranging from 0.7:1 to 10:1. The polymer according to the invention has a balanced property profile as regards absorptivity, gel strength, absorption speed and extractable componenents and can be advantageously produced by a continuous method.

Abstract: Disclosed is a water absorbing agent which consists of (a) particles of a water absorbing polymer and (b) a polymer which contains nitrogen and which contains 5-17 mol/kg protonated nitrogen atoms in relation to the overall weight of said nitrogen- -containing polymer. The inventive agent has an improved property profile with a high absorption capacity, improved fluid transmissibility and high water resistance.

Abstract: The invention relates to hydrogels capable of absorbing aqueous fluids, which hydrogels are produced by polymerization of olefinically unsaturated carboxylic acids or their derivatives. The hydrogels are characterized in that before, during or after the polymerization reaction and before drying a silicic acid alkali salt of the general formula (I) M2O×nSiO2 is added to the polymerization reaction mixture. In said formula M is an alkali metal and n is a number between 0.5 and 4. The hydrogel obtained in this way is then dried at an elevated temperature. The invention also relates to a method for producing said hydrogels and to their use for absorbing aqueous fluids.
