A process for producing an absorbent resin, which comprises polymerizing 1 mole of a lower alkyl acrylate and 0.07 to 0.5 mole of a polyhydric alcohol ester of a monoethylenically unsaturated carboxylic acid in an aqueous medium in the absence of an emulsifying agent, saponifying the resulting polymer with a basic substance in a water-lower alcohol medium, and then neutalizing the saponification product with an acid. |
