  • Process for making water-swellable material comprising coated water-swellable polymers
    Patent number: 8137746
    Abstract: This invention is directed to a process for making solid, typically particulate, water-swellable material comprising coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g., water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet-extensible material that has a tensile stress at break in the wet state of at least 1 MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material. The invention also relates to solid (particulate) water-swellable material obtainable by the process of the invention.
