Abstract
A method for the production of a salt-resistant absorbent resin, which comprises subjecting an aqueous solution of at least one monomer component (A) selected from the group consisting of unsaturated carboxylic acids and salts thereof to aqueous solution polymerization in the presence of from 1 to 30 parts by weight, based on 100 parts by weight of said monomer component (A), of an absorbent resin (B).
