Title:
PULVERULENT, CROSS-LINKED POLYMERS, CAPABLE OF ABSORBING AQUEOUS LIQUIDS
Document Type and Number:
WIPO Patent Application WO2002022717
Kind Code:
A8
Abstract:
The invention relates to absorbent, cross-linked polymers based on partially neutralised, 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.
