Abstract:
1. A superabsorber composition consisting of: a) a surface-crosslinked, water-absorbing polymer structure having a structure surface, b) from about 0.01 to about 5 wt % based on the weight of the water-absorbing polymer structures of a solid powder selected from aluminium salts having an average particle diameter in the range of from about 100 to about 600 μm wherein the solid powder is at least partly immobilized on the structure surface of the surface-crosslinked, water-absorbing polymer; and c) a binder selected from polypropylene glycols or polyethylene glycols, wherein the binder has a weight-average molecular weight M wherein the weight ratio of the solid powder of b) and the binder of c) is from about 10:1 to about 2:1, and wherein the elements b) and c) are applied to the structure surface of the surface-crosslinked, water-absorbing polymer structure, and wherein the solid powder are immobilized by said binder, and wherein the superabsorber composition has an SFC value, determined in accordance with the test method described herein, of from about 50×10
