摘　　要：用麦秸秆和玉米秆与丙烯酸接枝共聚制备高吸水性树脂，并测定了其在不同水体系（去离子水、自来水和0.9%NaCl溶液）中的吸水倍率。同时，研究了淀粉含量对吸水性能的影响。结果表明：利用麦秸秆制备的吸水性树脂在不同水体系中的吸水倍率可达70～400。Resin being highly absorbent of water was prepared by means of graft copolymerizations with wheat-and corn-straw and acrylic resin. The water absorption is tested in different water systematic （including deionized water, tap water and 0.9% Nacl solution）. In addition, the effect of the content of starch on water absorption is discussed, the result showed that the absorbent resin prepared by wheat straw can reach 70-400% in different water systems.
