PURPOSE: A producing method of a super absorbent resin is provided to reduce the gel cohesive property of a hydrogel polymer for easily cutting and crushing. CONSTITUTION: A producing method of a super absorbent resin comprises the following steps: producing a monomer composition containing a water-soluble ethylene-based unsaturated monomer and a polymerization initiator; producing a hydrogel polymer by inserting the monomer composition in a polymerization reactor(30) and polymerizing; cooling the surface of the hydrogel polymer to the temperature lower than the dew point using a cooler(50); and cutting and crushing the hydrogel polymer. |
