  • Patent number: 9534095
    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.

  • Publication number: 20070065503
    Abstract: A water-absorbing composition, a process for producing a water-absorbing composition, a composite comprising a water-absorbing composition, and the use of a water-absorbing composition for releasing an active substance (e.g., a wound treatment substance, a care substance, or combinations thereof) are disclosed. A water-absorbing composition can include active substance-doped water-absorbing polymer particles comprising: ?1.) an active substance in a quantity in the range from about 0.001 to about 30 wt. %; and ?2.) an absorber matrix in a quantity in the range from about 70 to about 99.999 wt. %. Also, a hygiene article and a wound treatment means, including a water-absorbing composition, are disclosed.
