| titleOfInvention | Water absorbent resin production method, water absorbent resin, and usage thereof |
| abstract | A method for producing a water absorbent resin comprises the steps of: (i) polymerizing a monomer including an unsaturated monomer containing a carboxyl group, in the presence of an internal cross-linking agent (A) having two or more radical polymerizable unsaturated groups in its single molecule and in the presence of a non-polymeric internal cross-linking agent (B) having in its single molecule two or more functional groups each of which allows formation of an ester bond or an amide bond by reacting with a carboxyl group, while crushing a cross-linked polymer hydrogel; and (ii) drying the cross-linked polymer hydrogel obtained in the step (i), wherein: an amount of the internal cross-linking agent (A) is 0.01 mol% or more and 0.2 mol% or less relative to an amount of the unsaturated monomer containing a carboxyl group, and a molar ratio (B)/(A) of the internal cross-linking agent (A) and the non-polymeric internal cross-linking agent (B) is 0.01 or more and 1.8 or less. |
