(57) [Abstract] [Purpose] The gel strength, gel stability, and "stickiness" of the gel surface after water absorption of superabsorbent polymer (especially when absorbing body fluids such as human urine that have large individual differences). At the same time improve. [Structure] (A) 100 parts by weight of a super absorbent polymer having a crosslinked structure and containing a carboxyl group and / or a carboxylate group as a constituent component of the polymer, and (B) A highly water-absorbing polymer composition comprising 0.05 to 10 parts by weight of a polyvalent metal sulfate of a metal selected from titanium, zirconium and vanadium. |
