PURPOSE: A producing method of a highly absorptive resin is provided to enable users to obtain the high quality highly absorptive resin having the desired particle size. CONSTITUTION: A producing method of a highly absorptive resin comprises the following steps: forming a monomer composition containing a water-soluble ethylene-based unsaturated monomer and a polymerization initiator; inserting the monomer composition into a polymerization reactor(30), and polymerizing and drying to obtain a water-absorbed gel polymer(40) in a sheet shape; and cutting and crushing the water-absorbed gel polymer. |
