  • PROCESS TO MAKE WATER-ABSORBING POLYMER STRUCTURE HAVING SUPERABSORBENT POLYMER INDEX
    Publication number: 20160106881
    Abstract: The present invention relates to a process for the production of a water-absorbing polymer structure, comprising the process steps: i) providing an untreated water-absorbing polymer structure having a degree of neutralization of at most 70 mol %; ii) bringing the untreated water-absorbing polymer structure into contact with an acidic component. The invention also relates to the water-absorbing polymer structures obtainable by this process, water-absorbing polymer structures, a composite, a process for the production of a composite, the composite obtainable by this process, foams, shaped articles, fibers, foils, films, cables, sealing materials, liquid-absorbing hygiene articles, carriers for plant and fungal growth-regulating agents, packaging materials, soil additives or building materials, and the use of a water-absorbing polymer structure.

  • Process for gentle mixing and coating of superabsorbers
    Patent number: 8349913
    Abstract: The present invention relates to a process for the production of a superabsorber, comprising as steps providing a water-absorbing polymer structure, bringing the water-absorbing polymer structure into contact with a modifying agent, preferably a modifying agent, and the further treatment of the water-absorbing polymer structure which has been brought into contact with the modifying agent. The further treatment is carried out at least partly in a rotating container. The invention furthermore relates to a device for the production of a superabsorber, superabsorbers, a composite, a process for the production of a composite, the composites obtainable by this process, chemical products, such as foams, shaped articles or fibers, and the use of a superabsorber.
