  • Powdery, crosslinked absorbent polymers, method for the production thereof, and their use
    Patent number: 6620889
    Abstract: The invention relates to crosslinked polymerizates which are capable of absorbing, which are based on partially neutralized, monoethylenically unsaturated monomers that carry acidic groups, which exhibit improved properties, in particular, with regard to their ability to transport liquids when in a swollen state, and which have been subsequently crosslinked on the surface thereof with a combination consisting of an organic crosslinker compound, with the exception of polyols, and of a cation provided in the form of a salt in an aqueous solution.
    Type: Grant
    Filed: August 29, 2001
    Date of Patent: September 16, 2003
    Assignee: Stockhausen GmbH & Co. KG
    Inventors: Richard Mertens, Jörg Harren
  • Powdery, cross-linked polymers which absorb aqueous liquids and blood, method for the production thereof and their use
    Patent number: 6605673
    Abstract: The invention relates to crosslinked polymerizates which are capable of absorbing, which are based on partially neutralized, monoethylenically unsaturated monomers that carry acidic groups, which exhibit improved properties, in particular, with regard to their ability to transport liquids when in a swollen state, and which are subsequently crosslinked on the surface thereof at temperatures ≧150° C. with a combination consisting of polyol used as a subsequent crosslinker compound and of a cation provided in the form of an aqueous solution.
