Abstract
A liquid-absorbing material composition containing a crosslinking agent (component A), N-vinylcarboxamide copolymer (component B) having a functional group capable of crosslinking with the component A, water (component C), a water-soluble organic solvent (component D) and a plasticizer (component E), a molded liquid-absorbing material prepared from the composition, a method of manufacturing the molded liquid-absorbing material, and uses thereof are provided. The liquid-absorbing material composition has a high flowability, and gives a uniform continuous layer so that it can be directly molded readily into film- or sheet-shaped molded liquid-absorbing material without requiring secondary processing as in the case of conventional water-absorbing polymer. Use of the liquid-absorbing material composition allows manufacture in short time of molded products which are excellent in liquid-absorbing performance that can be utilized as a freshness retaining agent, a moisture-conditioning agent, an agricultural and horticultural water-retaining sheet, a soil improving agent, an anti-dewing agent, sanitary goods, a waste liquid solidifying material, a water preventing sheet, a water running preventing shielding material, a pharmaceutical, a medical tool, a humectant or desiccant.
