摘要：
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.
