Abstract (en)
[origin: WO9615180A1] The present invention provides a superabsorbent material which comprises a combination of (1) an anionic superabsorbent in which from 20 to 100 % of the functional groups are in free acid form, and (2) an anion exchanger in which from 20 to 100 % of the functional groups are in basic form. The combination is particularly effective as a superabsorbent in the case of electrolyte containing solutions such as menses and urine.
