| 摘 要： | 对影响淀粉－丙烯酸－丙烯酰胺二元接枝共聚反应的引发剂用量、淀粉／单体比例、丙烯酸／丙烯酰胺比例、聚合温度、聚合时间等因素进行了考察，确定了淀粉二元接枝共聚反应的最佳工艺条件，合成了吸水率为７６０ｇ／ｇ、吸０．０６％ＣａＣｌ２溶液为１９２ｇ／ｇ、吸０．９％ＮａＣｌ溶液为１５５ｇ／ｇ的耐盐性高吸水树脂，从根本上解决了其抗盐怀能差的问题。

| Abstract: | The factors which influence graft polymerization of starch to polyacrylic-acylanide are investigated, such as the amount of initiator, the ratio of starch to monomer, the ratio of acrylic acid to acrylamide, the temperature and time of polymerization. The best technology is determined. The salt-resistance water absorbency resin which water absorptivity is 760(g/g),0.06% CaCl 2 solution 192(g/g), and 0.9% NaCl solution 155(g/g) is synthesized, which solves the salt-resistance problem of the resin. |
