摘要： [Object] To provide a method for producing a water-absorbent resin in powder form or particle form, which has excellent physical properties such as water absorption performance and the like, at high productivity.
[Solution] A method for producing a water-absorbent resin includes: a polymerization step of polymerizing a monomer, which is a raw material of the water-absorbent resin, to obtain a hydrous gel crosslinked polymer dispersed in an organic solvent; and a separation step of separating the organic solvent and the hydrous gel crosslinked polymer. The separation step includes transfer, compression, and discharge of the hydrous gel crosslinked polymer.-
