    摘要： The invention relates to open-cell, elastic foams consisting of melamine/formaldehyde resins having a drop absorption speed of less than five seconds and a formaldehyde emission in accordance with EU standard EN ISO 14184-1 of less than 100 mg formaldehyde/kg foam, to a method for producing hydrophilic, open-cell, elastic foams by (a) heating an aqueous solution or dispersion containing, respectively, at least one melamine/formaldehyde precondensate, an emulsifier, an expanding agent and a hardener, forming a foam and cross-linking the precondensate, (b) subsequently tempering the foam for a period of 1 to 180 minutes at 120 to 300 °C, whereby volatile parts are removed, and (c) treating, during or after tempering, with at least one hydrophilization agent and/or with ozone, a corona discharge or a plasma; and to the use of the foams in hygiene products for absorbing, distributing and immobilising body fluids.

    摘要： The invention relates to foams made from water-absorbing, basic polymers, which can be produced by: (I) foaming a cross-linkable aqueous mixture which contains (a) at least one basic polymer whose basic groups are optionally neutralized; (b) at least one cross-linking agent; (c) at least one surface active agent; (d) optionally at least one solubilizer; (e) optionally thickener, foam stabilizers, filling materials, fibers and/or cell nucleator and (f) optionally particle-shaped, water-absorbing acid polymers, wherein a gas that is inert to radicals is dissolved for foaming purposes in the cross-linkable, aqueous mixture at a pressure ranging from 2 to 400 bar, which is then relieved at atmospheric pressure or wherein foaming occurs by dispersing fine bubbles of a gas that is inert to radicals, and (II) crosslinking the foamed mixture by forming a foamy hydrogel and optionally regulating the water content of the foamy polymer to 1 to 60 percent by weight. The invention further relates to a method for the production of foams by implementing the above-mentioned measures (I and II) and to the utilization of the resulting foams in hygiene articles for the absorption of body fluids, in dressing materials to cover wounds, as sealing materials, packaging material, soil conditioners, soil substitutes, mud drainage, the absorption of acid aqueous wastes, for thickening aqueous paints in the disposal of paint residues, dehydrating water-containing oils or hydrocarbons or as material for filters in ventilation systems.
