Title:
WATER-ABSORBING RESIN AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2021/162085
Kind Code:
A1
Abstract:
The problem of the present invention is to provide a water-absorbing resin for which odor generated when the water-absorbing resin swells is sufficiently reduced while physical properties such as water-absorption performance of the water-absorbing resin are maintained. The above problem is solved by a water-absorbing resin with the surface thereof crosslinked, wherein the volatile component concentration is 3.5 ppm or less when the water-absorbing resin is left to stand for 15 minutes under conditions where the swelling magnification becomes 1.0 times.
