摘要： A process for preparing a water-absorbent resin comprising carrying out a reverse phase suspension polymerization in multi-steps of at least two steps when the water-absorbent resin is prepared by subjecting a water-soluble ethylenically unsaturated monomer to the reverse phase suspension polymerization in the presence of a crosslinking agent, the process for preparing a water-absorbent resin being characterized by adding a water-soluble chain transfer agent in an amount of 0.000012 to 0.01 mole per 1 mole of the water-soluble ethylenically unsaturated monomer used in a polymerization reaction to at least one step in the second and subsequent steps of the multi-steps, to carry out the polymerization reaction. The water-absorbent resin can be suitably used in hygienic materials such as disposable diaper and sanitary napkin.
