Abstract:
     A preparing process and a post-treating method of a high-hydroscopicity resin are disclosed. The post-treating method includes segmental polymerization and expansive washing. The produced resin has the advantages of high water and salt absorption, little residual water-insoluble compound, excellent elasticity after water is absorbed, and high repeatability of absorbing-releasing water.
