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.

Abstract: The invention relates to a method for the secondary gel and/or surface cross-linking of water-absorbent polymers, according to which the polymers are treated with a surface cross-linking solution and during or after this treatment subjected to secondary cross-linking and drying by temperature elevation. The method is characterized in that as cross-linking agent the solution for secondary surface cross-linking contains, dissolved in an inert solvent, a compound of formula (I) in which R , R , R , R independently of each other are hydrogen, C1-C12-alkyl, C1-C12-alkenyl, C6-C12-aryl or C1-C12-alkoxy; R is C1-C16-alkyl, C1-C4-hydroxyalkyl, C6-C12-aryl, C1-C16-alkenyl or a group of the formula -(CH2)n-COOH or -(CH2)n-SO3H in the acid form or in the form of their metal salts, ammonium salts or triethanol ammonium salts or -(CH2-CH2-O-)m-R ; R is hydrogen or C1-C16-alkyl; n is a number between 1 and 10; and m is a number between 1 and 20. The invention also relates to the liquid-absorbent polymers obtained in this manner and to their use in hygiene articles, packaging materials and nonwovens.
