WATER ABSORBENT RESIN COMPOSTION AND PRODUCTION METHOD THEREOF |
摘要 |
<p>The production method of a water absorbent resin composition including a particulate water absorbent resin, wherein: 95 wt % or more of particles whose particle diameter is less than 850μm and not less, than 106μm are contained, and a weight average particle diameter of the particles is less than 500μm and not less than 300μm and a logarithmic standard deviation (σξ) of a particle size distribution is 0.45 or less, and a water-soluble component of the water absorbent composition is 35 wt % or less, and a multivalent metal component is contained, and an extraction rate of the multivalent metal component is 5.0 wt % or more and less than 100 wt %, thereby providing the water absorbent resin composition, free from any coagulation of particles in high humidity, which has superior absorbent property in terms of an absorbency and a diffusing absorbency under pressure.</p> |
