(57) [Summary]n(I) the following components: (a) a monoethylenically unsaturated monomer containing an optionally neutralized acid group; (b) optionally another monoethylenically unsaturated monomer; (c) a crosslinking agent; A) an initiator, (e) 0.1 to 20% by weight of at least one surfactant, (f) optionally at least one solubilizer and (g) optionally a thickener, a foam stabilizer, a polymerization control. Foamable polymerizable aqueous mixture containing an agent, a filler and / or a cell nucleating agent, wherein a gas inert to radicals for foaming is polymerized under a pressure of 2 to 400 bar. Dissolved in the mixture, subsequently releasing said mixture to atmospheric pressure, and (II) polymerizing the foamed mixture while forming a foamed hydrogel, optionally reducing the water content of the foamed polymer to 1 to 60% by weight. To adjust In the resulting water-absorbent foam-like crosslinked polymer, a method for producing the water-absorbent foam-like crosslinked polymer, a hygiene product used for absorbing body fluid of the polymer, and a dressing material for covering wounds, and sealing Use as material, soil conditioner, soil substitute and packaging material. |
