More Information
Summary: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.
