WATER-SWELLABLE HYBRID MATERIAL WITH INORGANIC ADDITIVES AND PROCESS FOR ITS PREPARATION

Water swellable hybrid material comprises a structurally crosslinked polymer matrix and bound inorganic particulate solid. The hybrid material has a time-dependent swelling behavior corresponding to an uptake of water of at least 7.5 times related to weight of the hybrid material within one hour. In...

More Information
Summary:Water swellable hybrid material comprises a structurally crosslinked polymer matrix and bound inorganic particulate solid. The hybrid material has a time-dependent swelling behavior corresponding to an uptake of water of at least 7.5 times related to weight of the hybrid material within one hour. Independent claims are included for: (1) preparing water swellable hybrid material which comprises providing a reaction mixture comprising at least a polymerizable component and at least one solvent, where the pH of the reaction mixture is less than 7, mixing the reaction mixture with inorganic solid particulate, adding at least a crosslinker, initiating polymerization and controlling the polymerization reaction, so that the volume of the reaction mixture increases; (2) the hybrid material obtained by the process, and (3) a soil auxiliary material comprising the hybrid material and at least a material such as ground, humus, sand and/or turf.
