Abstract
The invention relates to an absorbent structure (30, 38, 50, 58, 62, 66) that is produced on the basis of superabsorbent polymer materials. Said superabsorbent polymer materials are interlinked by means of a thermoplastic polymer. The inventive structure is produced by extruding the superabsorbent polymer materials with a moisture content of at least 0.5 wt.-% based on the overall weight of the superabsorbent polymer and evaporating the liquid of the superabsorbent polymer materials and inducing foaming of the structure.
