摘　　要：采用60Co-γ射线辐射引发淀粉-丙烯酸静置悬浮聚合,制备了粒径250~850μm左右的球状吸水树脂。考察了剂量率、剂量对高吸水树脂吸液性能的影响,并对球状吸水树脂进行了表面处理,结果表明,球状吸水树脂通过表面处理后,大大提高了吸液速率。A 250～850μm water-absorbent sphere resin,starch-acrylate copolymer,was prepared by(^(60)Co-γ) ray irradiation-initiated copolymerization in inverse suspension way.The effect of dose rate and integral dose on the water-absorbent sphere resin was investigated,and the water-absorbent sphere resin was surface treated.The result showed the speed of the water-absorbent sphere resin by surface treated was more higher than it not be surface treated.
