WATER ABSORBENT RESIN AND METHOD FOR PRODUCING SAME |
摘要 |
<p>Object The main object of the present invention is to provide a water-absorbent resin having a suitable particle size, strong particle strength, excellent adhesion to fibers, and excellent flowability as powders as well as properties suitable for a water-absorbent material used in a hygienic material, such as excellent general absorption properties as a water-absorbent resin, and to provide a process for producing the same. Another object of the present invention is to provide an absorbent material and an absorbent article using the water-absorbent resin. Means for Achieving the Object A water-absorbent resin having an aspect ratio of 1.0 to 3.0 and a median particle size (D) of 100 to 2,000 µm in which primary particles having an aspect ratio of 1.1 to 200 and a median particle size (d) of 50 to 600 µm are agglomerated.</p> |
