摘要

process for preparing a water absorbing polymeric structure, water absorbing polymeric structure, composite, process for preparing a composite, foams, molded articles, sheets, films, cables, sealing materials, fluid absorbent hygiene articles, vehicles for fungal and plant growth regulating compositions, packaging materials, soil additives or building materials, use of the water-absorbing polymeric structure or composite, and use of a salt. The present invention relates to a process for the preparation of water absorbing polymeric structures, comprising the following process steps: i) providing an untreated water absorbing polymeric structure; and ii) contacting the untreated water-absorbing polymeric structure in contact with a salt, comprising a divalent or higher valence cation of a metal, and at least one organic base such as an aliou. The invention also relates to water-absorbent polymeric structures obtainable by this process, to water-absorbent polymeric structures, to a composite comprising a water-absorbent polymeric structure and a substrate, to a process for preparing a composite, to the obtainable composite. by that process to chemicals such as foams, molded articles and fibers comprising water absorbing polymeric structures or a composite, the use of water absorbing polymeric structures or a chemical composite, and the use of a salt in the surface treatment of water absorbing polymeric structures.
