- 摘要：
PROBLEM TO BE SOLVED: To obtain a particulate water absorbent that produces no odor after a water absorbent resin is swollen and gives no unpleasant smell in a practical use in addition to the conventional various physical properties (water absorption rate, non-pressurized absorption rate, pressurized absorption rate, particle size and the like).
SOLUTION: The particulate water absorbent that generates no offensive odor when swollen is obtained by controlling a raw material-derived impurity and/or a by-product-caused specific odor component after heat treatment is performed at a high temperature.
