| Abstract: | Tacking starch,sodium acrylate partially neutralized and acrylamide,using water-soluble initiator, a " supper absorbent resin" has been prepared by the stepwise method through cross graft polymerization. The absorption amount is 3000g/g deionized water and 140g/g of 0. 9 percent NaCl water solution, respectively. Not only the mechanism of polymerization by the stepwise method and those of water absorbtion, but also the effects of posttreatment on the water-absorbtion capability of resin are discussed. |
