Abstract (en)

[origin: WO9615163A1] The invention provides a superabsorbent material which comprises a combination of (1) a cationic superabsorbent in which from 20 to 100 % of the functional groups are in basic form, and (2) a cationic exchanger in which from 50 to 100 % of the functional groups are in acid form. The combination is particularly effective as a superabsorbent for electrolyte containing solutions such as menses and urine.
