摘　　要：针对吸水树脂使用过程中存在的吸盐水倍率低,降解性能差等问题,以过硫酸钾为引发,N,N'-亚甲基双丙烯酰胺为交联剂,环己烷为连续相,玉米淀粉,丙烯酸和丙烯酰胺为原料,采用反相悬浮聚合法合成淀粉接枝可降解高吸水性树脂微球并进行了相关表征。最佳反应条件下,得到的吸蒸馏水倍率为379.2 g/g,吸0.9%的Na Cl水溶液的倍率为88.1 g/g。最后考察了吸水树脂的保水性能和降解性能,从而为吸水树脂微球应用于农林业保水保肥提供理论指导。The problems existing in application of superabsorbent resin should be solved. For example,absorbency ration of saline solution and degradable property were not desirable. The method was as follows： the starch-grafted degradable superabsorbent resin was synthesized by inverse suspension polymerization method, using acrylic acid,acrylamide and corn starch as raw materials,N,N＇-methylenebisacrylamide as crosslinking reagent and cyclohexane as continuous phase and it was characterized. The effects of amount of the cross linker,corn starch content and dispersant content on absorbency of the superabsorbent resin were investigated in details. The absorbency of the superabsorbent resin under optimum condition was up to 379. 2 g/g in distilled water and 88. 1 g/g in 0. 9% Na Cl solution. The properties of water retention and degradability were investigated lastly. This superabsorbent resin microsphere will provide theoretical guidance for the application of agriculture and forestry for water retention and fertilizer retention.
