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.

Process for gentle mixing and coating of superabsorbers

A process for producing an absorbent polymer structure (Pa) by treating the outer portion of an untreated absorbent polymer structure (Pu1). The process includes the step of bringing the outer portion of the untreated absorbent polymer structure (Pu1) into contact with an aqueous solution including at least one chemical cross-linker and at least one inorganic compound in dispersed colloidal form. The process also includes the step of heating the absorbent polymer structure, of which the outer portion has been brought into contact with the aqueous solution, at a temperature within a range from about 40 to about 300&#xb0; C., so that the outer portion of the absorbent polymer structure is more strongly cross-linked in comparison to the inner portion and the inorganic compound is at least partly immobilized in the outer portion of the absorbent polymer structure.

Absorbent polymer structure with improved retention capacity and permeability

An oligomerized polyorganosiloxane cocondensate which may be obtained, in part, by mixing an water-soluble amino-functional organosilane represented with at least one of the followoing: a fluoro-functional organosilane, an organosilane, and an organosilane. The cocondensate may be used, for example, in a method of treating surfaces.
