PURPOSE:To obtain a resin having improved absorbability of water and body fluid and giving a swollen gel with improved strength, by reacting monomers containing an ethylenic unsaturated monocarboxylic acid with a specific oil- soluble polyfunctional epoxy compound, thereby introducing the epoxy compound component into the resin. CONSTITUTION:The objective resin is composed of a polymer produced by the polymerization of monomers composed mainly of an ethylenic unsaturated monocarboxylic acid and/or its alkali metal salt. In the production of the above resin, 100pts.wt. of said monomers are made to react with 0.0005-3pts.wt. of an oil-soluble polyfunctional epoxy compound having a water-solubility of <=0.3g per 100g of water at 20 deg.C [e.g. the compound of formula I, II (R is group of formula III, etc.), etc.] to introduce the epoxy compound component into the polymer. The resin is useful as a body fluid absorbent for sanitary napkin, hygienic goods, etc.
