摘　　要：本文应用玉米秆、棉花秆、地瓜蔓等不同种类纤维素农作物秆与丙烯酸接枝共聚制备了高倍率的吸水树脂。研究了农作物秆与食用淀粉不同比例含量及不同的吸水体系（包括吸去离子水、自来水及雨水）等因素对吸水性能的影响。采用棉花秆与丙烯酸的接枝产物吸去离子水850多倍，用玉米秆／地瓜淀粉混合物制备的接枝产物吸自来水和雨水分别为550多倍。这对玉米秆、棉花秆及地瓜蔓等富含纤维素农作物秆的深加工与应用开辟了一条途径。The different cellulose of crops stalks such as corn, cotton, and sweet potato were studied by graft copolymerization using acrylic acid. Many factors, such as ratios of starch and cellulose, de - ionized water, running water and rain water which affected the absorbency of copolymers were researched. The copolymer prepared by cotton stem cellulose and acrylic acid can absorb de - ionized 850g/g, running water 500g/g, and rain water 500g/g. The copolymer of sweet potato starch and corn crop cellulose （ 3 ： 2 by weight） with acrylic acid can absorb running water 550gig, and rain water 500g/g.
