摘要： This invention relates to a process for producing a quality-improved water-absorbent polymer in which the aqueous liquid ( I ), which is obtained by mixing in an aqueous medium at least one kind of a water-soluble salt ( A ) selected from a group of halogenated compounds, sulfates, acetates, and nitrates, which are derived from at least one kind of a polyvalent metal selected from a group of aluminum, calcium, and magnesium, with at least one kind of a water-soluble salt ( B ) selected from a group of monovalent metal salts and ammonium salts, which are derived from at least one kind of an oxyacid selected from a group of sulfurous acid and thiosulfuric acid, is mixed with a water-absorbent polymer ( II ) in a proportion of that the water-soluble salt of the polyvalent metal ( A ) is in a range of 0.1 ∼ 10 parts by weight against 100 parts by weight of the water-absorbent polymer ( II ) and the water-soluble salt of the oxyacid ( B ) is in a range of 0.1 ∼ 10 parts by weight against 100 parts by weight of the water-absorbent polymer ( II ). The mixture which is obtained by mixing the aqueous liquid ( I ) with the water-absorbent polymer ( II ) has relatively-improved capacities in the fluidity and the amount of residual monomers. This invention displays a more sufficient effect by compulsorily bringing the mixture into contact with an oxygen-containing gas.
