WATER ABSORBENT RESIN COMPOSITION AND ITS PRODUCTION PROCESS |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a water absorbent resin composition and its production process which hardly causes gel blocking, excels in liquid permeating property and liquid diffusing property and has high absorptive capacity and resistance against physical damages. <P>SOLUTION: The water absorbent resin composition contains water absorbent resin particles produced by polymerizing monomers containing acrylic acid and/or its salt. The composition has mass average particle diameter of 100-600 μm and contains water-soluble polyvalent metal salt particles and surface cross-linked water absorbent resin particles. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
