<p>PURPOSE:To obtain the title structure suitable for absorbing condensed water such as a sheet to be laid in a food container, by incorporating a fibrous carboxymethylcellulose salt dispersion with a cationic water-soluble polymer to produce a paper stock with part or the whole of the salt converted to polyelectrolyte complex followed by dehydration and molding of the paper stock. CONSTITUTION:(A) A fibrous carboxymethylcellulose salt dispersion is incorporated with (B) a cationic water-soluble polymer containing recurring units each having primary, secondary, tertiary and/or quaternary nitrogen atom and not containing any crosslinkable functional groups other than the above nitrogen atom to produce a paper stock with part or the whole of the salt converted to polyelectrolyte complex, and the paper stock is then dehydrated and molded, thus affording the objective swellable structure.</p> |
