Patent ID: 7196139

Claim:
A water-absorbent resin composition, comprising a water-absorbent resin (R1) obtained by aqueous solution polymerization and a water-absorbent resin (R2) obtained by reversed-phase suspension polymerization or reversed-phase emulsion polymerization and satisfying any of the following conditions (a)–(c), (a) that a capillary suction force capacity of a 0.9 wt. % physiological saline in the gradient of negative pressure of 20 cm be not less than 20 g/g, (b) that an absorption capacity under pressure of a 0.9 wt. % physiological saline under be 4.83 kPa at 60 mm. be not less than 20 g/g, and (c) that a flow conductivity of a 0.69 wt. % physiological saline be not less than 10 (unit: 10 −7 ×cm 3 ×s×g −1 ); wherein the water-absorbent resin (R1) is obtained by aqueous solution polymerization of polymerizable monomers comprising 70–100% of acrylic acid and/or salts thereof and the water-absorbent resin (R2) obtained by reversed-phase suspension polymerization or reversed-phase emulsion polymerization of polymerizable monomers comprising 70–100 mol % of acrylic acid and/or salts thereof.
