Water-swellable hybrid material with inorganic additives and process for its preparation

(57)    Abstract

The present invention relates to a water-swellable material comprising an inherently crosslinked polymer matrix and inorganic solid particles bound therein with a time -dependent swelling behaviour that corresponds to a water uptake of at least 7.5 times the inherent weight of the hybrid material within one hour, as well as the applications thereof. The present invention further relates to a method for manufacture of such a water-swellable hybrid material.
