Abstract

PURPOSE: To obtain the titled polymeric material suitable as sanitary cotton, napkin or the like, by polymerizing an α,β-unsaturated carboxylic acid monomer (alkali metal salt) in the presence of a water-soluble polymer or/and a water- soluble surfactant.
CONSTITUTION: The titled polymeric material is obtained by polymerizing an α,β-unsaturated carboxylic acid monomer such as (meth)acrylic acid or/and its alkali metal salt in the presence of about 0.1W50wt% water-soluble polymer (e.g., polyvinyl alcohol, polyethylene oxide, dextrin) or/and about 0.001W20wt% water-soluble surfactant (e.g., polyoxyethylene alkyl ether, polyoxyethylene sorbitan fatty acid ester). The polymeric material thus produced, when contacted with water, does not show a phenomenon of forming undissolved lumps and has an ability of absorbing a large amount of water within a short time.
