The present invention relates to a method of producing a superabsorbent resin. Method for producing a highly water-absorbing resin of the present invention is to form the first polymer to the proceeding a thermal polymerization or photo-polymerization monomer to a composition comprising a water-soluble ethylenically unsaturated monomer and a polymerization initiator; Proceeds in the thermal polymerization or photopolymerization monomer composition comprising a water-soluble ethylenically unsaturated monomer and a polymerization initiator to form a second polymer; Drying the first polymer; The dried wherein the step of grinding the first polymer; And comminuted with the first polymer, the second polymer was a mixture of free swelling as a cross-linking agent solution comprising the step of cross-linking reaction for the first polymer and the second polymer. According to the invention, it is possible to obtain a super-absorbent resin having a high absorption capacity under pressure and SAT beam.
