摘　　要：以过硫酸铵为引发剂，Ｎ，Ｎ’一亚甲基双丙烯酰胺为交联剂，制备了玉米淀粉和丙烯酸的接枝共聚物高吸水性树脂，考察了有关聚合条件对高吸水性树脂性能的影响，并对其在食品保鲜方面进行了试验。结果表明，该树脂具有优良的加压保水能力，在食品保鲜应用上有显著效果。Starch - acrylic acid graft copolymeric superabsorbents were prepared by using ammonium persulfate as initator, N, N' - methylene bisacrylamide as crosslinking agent. The influence of polymerization conditions on the water - absorbing capacity of superabsorbents were investigated. The properties of this superabsorbents had also been studied. The effect of apptying this products to keep food fresh was very satisfied.
