  • Patent number: 7700153
    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 wet-elongation of at least 400%, or even more preferably at least 500%, and preferably 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.

  • Publication number: 20040039300
    Abstract: The present invention is a liquid handling member, which comprises a first zone and a second zone connected to a suction device, wherein the second zone circumscribes a second zone volume which is at least to 50% filled with a non-liquid fluid, and wherein the first zone and the second zone are separated by a membrane assembly which is capable of maintaining a pressure differential between the second zone and the first zone without permitting air to penetrate from said first zone to said second zone. The assembly comprises further a first porous membrane region oriented towards the first zone, and a second region oriented towards the second zone, which is capable of holding liquid, and which is in liquid communication with the pores of said porous membrane region.
