    Abstract: Disclosed are superabsorbing foams containing superabsorbing fibers and/or fruit fibers and a method for producing superabsorbing foams having improved wet fastness. According to said method, a cross-linkable aqueous mixture comprising at least 50 mol percent of neutralized, monoethylenically unsaturated monomers containing acid groups or at least one basic polymer, cross-linking agents, superabsorbing fibers, and/or fruit fibers, and at least one surfactant is foamed, whereupon the monomers contained in the foamed mixture are polymerized or the basic polymers are crosslinked, resulting in a foam-type hydrogel being formed. Also disclosed is the use of the foams obtained by means of said method in hygiene products used for absorbing body liquids, bandaging material used for covering wounds, as a sealant, packaging material, soil conditioner, soil substitute, for dewatering mud, thickening aqueous lacquers when disposing of leftover lacquer quantities, dewatering water-containing oils or hydrocarbons, or as a material for filters in ventilation systems.

    Abstract: Foams composed of water-absorbing basic polymers, obtainable by (I) foaming a crosslinkable aqueous mixture including (a) at least one basic polymer whose basic groups have optionally been neutralized, (b) at least one crosslinker, (c) at least one surfactant, (d) optionally at least one solubilizer, (e) optionally thickeners, foam stabilizers, fillers, fibers and/or cell nucleators, and (f) optionally particulate water-absorbing acidic polymers, by dissolving a gas which is inert toward free radicals in the crosslinkable aqueous mixture under a pressure from 2 to 400 bar and subsequently decompressing the crosslinkable aqueous mixture to atmospheric or by dispersing fine bubbles of a gas which is inert toward free radicals, and (II) crosslinking the foamed mixture to form a hydrogel foam and if applicable adjusting the water content of the polymer foam to 1-60% by weight. Preparation of the foams by application of the abovementioned measures (I) and (II) and use of the thus obtainable foams in hygiene articles to absorb body fluids, in dressing material to cover wounds, as a sealing material, as a packaging material, as a soil improver, as a soil substitute, to dewater sludges, to absorb aqueous acidic wastes, to thicken waterborne paints or coatings in the course of disposing of residual quantities thereof, to dewater water-containing oils or hydrocarbons or as a material for filters in ventilation systems.

    Abstract: A water absorbing foamed hydrogel obtainable from a polymerization mixture of acid group containing monoethylenically unsaturated (MEU), crosslinker, initiators, surfactant, solvent, and a cell nucleus former, where during foaming a gas inert to radicals is dissolved in the aqueous mixture. A water absorbing foamed hydrogel obtainable by (I): foaming an aqueous polymerization mixture of: (a) acid group containing monoethylenically unsaturated monomers (MUM) at least 50% neutralized, (b) optionally other MUM, (c) a crosslinker, (d) initiators, (e) at least one surfactant, (f) optionally at least one solvent, and (g) a cell nucleus former, where during foaming a gas at a pressure of 2-400 bar and inert to radicals is dissolved in the aqueous mixture, the mixture is adjusted to atmospheric pressure, so that a foam is obtained by dispersion of the fine bubbles of inert gas, and (II): the foamed mixture is polymerized with formation of a foamed hydrogel, and the water content of the polymerizate is adjusted to 1-60 wt.%. Independent claims are included for: (1) a process for preparation of the hydrogels as described above, where the crosslinker is a (meth) acrylic acid esterified addition product of 6-24 mole ethylene oxide and 1 mole trimethylol propane; and (2) polymerization of a nonwoven impregnated with the foamed polymerization mixture.
