摘要： In at least one embodiment, a particulate water-absorbing agent is provided which not only ensures the many conventional physical properties (absorption rate, centrifuge retention capacity, absorbency against pressure, particle size distribution etc.) but also prevents odor which is generated after the resin is swollen by absorption. The water absorbent agent of an embodiment of the present invention therefore does not cause odor in actual use. As a result of intensive study of the foregoing problem, an embodiment of the present invention offers a way of controlling a specific odor component, which is generated from impurities and/or by-product derived from the raw material, after the high temperature process. In this way, an embodiment of the present invention successfully provides a water absorbent agent not causing odor after the resin is swollen by absorption.
