摘要
A process of producing a water absorptive resin, wherein a water absorptive polymer which comprises cross-linked poly(metal salt of acrylic acid) as a major component is impregnated with water, and the water-impregnated water absorptive polymer is exposed to one of a high- temperature highly-humid atmosphere or a ultraviolet radiation, to thereby partially release the cross-linkage of the cross-linked poly(metal salt of acrylic acid).
