Abstract
The present invention relates to a process for the preparation of water-absorbing polymer structures, comprising the following process steps: I) providing an untreated, water-absorbing polymer structure; and II) bringing the untreated, water-absorbing polymer structure into contact with a salt comprising a divalent or higher-valent cation of a metal and at least one organic base as anion. The invention relates also to the water-absorbing polymer structures obtainable by that process, to water-absorbing polymer structures, to a composite comprising a water-absorbing polymer structure and a substrate, to a process for the preparation of a composite, to the composite obtainable by that process, to chemical products, such as foams, molded articles and fibers comprising water-absorbing polymer structures or a composite, to the use of water-absorbing polymer structures or of a composite in chemical products and to the use of a salt in the treatment of the surface of water-absorbing polymer structures.
