| abstract |
The invention relates to absorbent, crosslinked polymer products based on partially neutralized, monoethylenically unsaturated monomers bearing acid groups, which have improved properties, particularly with respect to their capability of conveying liquids in their swollen state, and which have been subjected to a secondary crosslinking at their surface using a combination of an organic crosslinker compound, with the exception of polyols, and a cation in the form of its salt in an aqueous solution. |
