SUPERABSORBING FOAM, METHOD FOR THE PRODUCTION THEREOF, AND USE THEREOF

WIPO Patent Application WO2004035668

A3

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.
