Abstract
The present invention relates to a process for producing water-absorbing polymer particles having an improved profile of properties, comprising thermal surface postcrosslinking in the presence of a salt of a polyvalent metal cation and a complexing anion and subsequent aftertreatment, the aftertreatment comprising coating with a salt of a polyvalent metal cation and a non-complexing anion, and remoisturization with further drying.
