ABSTRACT:
A process is provided for the production of a highly water-absorbing resin comprising a polymer obtained by polymerizing a monomer composition mainly composed of an ethylenically unsaturated monocarboxylic acid and/or an alkali metal salt thereof. The process comprises incorporating an oil-soluble polyfunctional epoxy compound having a solubility in 100 g of water at 20.degree. C. of not more than 0.3 g into the polymer by adding 0.0005-3 parts by weight of the oil-soluble polyfunctional epoxy compound to 100 parts by weight of the polymer or the monomer composition to be subjected to polymerization and thereby causing crosslinking.
