Pulverulent, crosslinked polymers which absorb aqueous liquids and blood

   
   

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.degree. C. with a combination of polyol as after-crosslinking compound and a cation in the form of an aqueous solution.

L'invenzione riguarda i polimeri assorbenti e uniti con legami atomici incrociati che sono basati sul neutralizzato su parzialmente, i monomeri monoethylenically insaturi che trasportano i gruppi acidi ed ha migliorato le proprietà, in particolare rispetto alla loro capienza per trasporto dei liquidi nello swollen dichiari e che dopo-sono stati uniti con legami atomici incrociati sulla loro superficie alle temperature almeno di 150.degree. C. con una combinazione del polyol come dopo-unendo con legami atomici incrociati residuo e un catione sotto forma d'una soluzione acquosa.
