     摘要目的合成超强吸水树脂。方法以环己烷和司盘60作为油相，以聚乙二醇(200)双丙烯酸酯作为交联剂，K2S2O8作为引发剂，采用反相悬浮聚合法制备。结果得到的产品呈颗粒状，吸去离子水倍率为715.1 g/g，吸生理盐水的吸液倍率达到112.3 g/g。结论交联剂用量、引发剂用量、搅拌速度、预聚液的滴加速度及反应温度对超强吸水树脂性能有很大的影响。

    Abstract Objective To synthesize the superabsorbent polymer microspheres. Methods The microspheres were prepared when using cyclohexane as the dispersing phase, span 60 as the dispersing agent, PEGdiacrylate as the crosslinker and potassium persulfate as the initiator. Results The amounts of water absorption of the microspheres were 715.1 g/g in deionized water and 112.3 g/g in saline. Conclusion The performance of the superabsorbent polymer microspheres is greatly affected by initial concentrations of dispersing agent and crosslinker, reaction temperature, agitation speed and dripping speed of the starting material. ......
