Abstract: PURPOSE:To obtain the titled polymer, having improved salt resistance and high water absorption rate, and useful for sanitary materials, etc., by dispersing or suspending an aqueous solution containing a carboxyl group-containing monomer in a hydrocarbon, etc. in the presence of an oil-soluble cellulose ester, etc., polymerizing the monomer, adjusting the water content, and crosslinking the resultant polymer. CONSTITUTION:An aqueous solution of a carboxyl group-containing water-soluble ethylenically unsaturated monomer, e.g. acrylic acid, is dispersed or suspended in a hydrocarbon, e.g. cyclohexane, or a halogenated aromatic hydrocarbon, and polymerized. In the process, a cellulose ester, e.g. cellulose acetate, or cellulose ether, e.g. ethyl cellulose, which is soluble in oil at the polymerization temperature is used as a protective colloid, and the water content is adjusted to 10-40wt% after the polymerization. The resultant polymer is then crosslinked with a crosslinking agent, e.g. ethylene glycol diglycidyl ether, having two or more functional groups reactive with carboxyl groups or carboxylate groups to give the aimed polymer.
