  • Pulverulent, cross-linked polymers capable of absorbing aqueous liquids
    Patent number: 7285599
    Abstract: The invention relates to absorbent, cross-linked polymers based on partially neutralized, monoethylenically unsaturated monomers that bear acidic groups. Said polymers exhibit improved properties with regard to their ability to transport liquids in a swollen state. The surface of the polymers is postreticulated, using a combination of an organic cross-linking compound, excluding polyols, and a cation that is in salt form in an aqueous solution.
    Type: Grant

  • Pulverulent, crosslinked polymers which absorb aqueous liquids and blood
    Patent number: 6831142
    Abstract: The invention relates to absorptive, crosslinked polymers which are based on partly neutralized, monoethylenically unsaturated monomers carrying acid groups, and have improved properties, in particular in respect of their capacity for transportation of liquids in the swollen state, and which have been after-crosslinked on their surface at temperatures of at least 150° C. with a combination of polyol as after-crosslinking compound and a cation in the form of an aqueous solution.
