Abstract (en)
[origin: WO2010057823A1] A mixture of superabsorbers having different surface postcrosslinking, in particular a mixture of screen sections of a base polymer, said sections being surface postcrosslinked differently, exhibits improved absorption and retention compared to a uniformly surface postcrosslinked superabsorber.
