WATER-ABSORBENT RESIN DISPERSION AND POLYURETHANE COMPOSITION |
摘要 |
<p>A water-absorbent resin dispersion comprising a water-absorbent resin (B) or a hydrous gel thereof dispersed in a liquid or heat-meltable organic active-hydrogen compound (A), wherein said resin (B) is formed by the polymerization of a water-soluble monomer or its precursor and a cross-linker and/or a polysaccharide in the compound (A); and a process for producing a polyurethane resin by the reaction of the dispersion with an organic polyisocyanate compound. As the polyurethane resin is excellent in the capacity and rate of absorption, it is useful as absorbent articles such as paper diaper and sanitary goods, humidity modifiers, cutoff material, and so forth.</p> |
