摘　　要：采用反相悬浮聚合法,以过硫酸钾为引发剂,N,N-亚甲基双丙烯酰胺为交联剂,以淀粉为主要原料,与丙烯酰胺、丙烯酸接枝共聚制备了高吸收性树脂。讨论了搅拌速率、分散剂的种类、引发剂用量、交联剂用量、丙烯酸的中和度、环己烷与水的比例对接枝共聚物吸水性能的影响。制备得到的树脂吸水能力可达600g/g,吸0.9%的生理盐水达70g/g。A kind of high absorbent resin of starch grafting with acrylamide and acrylic acid by inverse suspension method using sodium sulfite as initiator, N, N-methylene--bis--acrylamide as cross--linking agent. The influence of the rata of agitation, the sort of dispersant agent ,the amount of initiator and cross --linking agent , the neutralized degree of acrylic acid and the ratio of cyclohexane to water on the capability of the graft --copolymer were discussed. The absorption of the resin is 600（g/g） for water and 70 0. 9% （g/g） for NaCI solution.
