| abstract |
The present invention relates to a process for the production of a superabsorber, comprising as steps: (a) provision of a water-absorbing polymer structure; (b) bringing the water-absorbing polymer structure into contact with a modi-fying agent, preferably an aqueous surface-modifying agent; (c) further treatment of the water-absorbing polymer structure which has been brought into contact with the modifying agent; Wherein at least the further treatment in process step (c) is carried out at least partly in a rotating container. The invention furthermore relates to a device for the pro-duction of a superabsorber, superabsorbers, a composite, a process for the produc-tion of a composite, the composites obtainable by this process, chemical products, such as foams, shaped articles or fibres, and the use of a superabsorber. |
