The present invention relates to water-absorbing polymer structures, whose surface has been brought into contact with a compound comprising a polycation and at least one anion. The invention further relates to a process for treating the surface of water-absorbing polymer structures, the surface-treated water-absorbing polymer structures obtainable by this process, a composite comprising a surface-treated, water-absorbing polymer structure as well as a substrate, a process for production of a composite, the composite obtainable by this process, chemical products such as foams, formed bodies, and fibers comprising surface-treated water-absorbing polymer structures or a composite, the use of surface-treated, water-absorbing polymer structures or of a composite in chemical products as well as the use of compounds comprising a polycation with a given structure for the treatment of the surface of water-absorbing polymer structures.
A water-absorbing polymer structure, whose surface has been brought into contact with a compound comprising a polycation and at least one anion and which has an absorption under a pressure of 50 g/cm2 of at least about 16 g/g.
A water-absorbing polymer structure, whose surface has been brought into contact with a compound comprising a polycation and at least one anion, wherein the compound comprising a polycation and at least one anion has a weight average molecular weight of more than about 3,000 g/mol.
A process for treatment of the surface of water-absorbing polymer structures, comprising the following steps:
