摘　　要：以N,N’-亚甲基双丙烯酰胺(MBA)为单体,过硫酸钾为引发剂,研究了MBA与纤维素在离子液体中的接枝共聚反应。通过正交单因素实验,研究了反应时间、单体用量、反应温度、引发剂用量对接枝效果的影响。实验结果表明:当反应时间为2 h,单体与纤维素质量比为3∶1,反应温度为50℃,引发剂用量为0.05 g时,接枝效果最好。此条件下,MBA与纤维素的接枝率可达38.06%。The grafting of N, N＇-methylenebisacrylamide （MBA） onto cellulose was conducted using 1-butyl-3-methylinidazolium chloride ionic liquid （[Bmim]Cl） as reaction medium and potassium peroxydisulfate as initiator. The graft conditions, i.e., reaction time, monomer concentration, reaction temperature and initiator dosage etc. on the graft efficiency were optimized by orthogonal and signal-factor experiments. The results showed that the optimal conditions included 2 h of the reaction time, 3 ： 1 of the mass ratio of monomer and cellulose, 50℃ of the reaction temperature and 0.05 g of the initiator dosage. Under the above optimal conditions, the grafting efficiency of cellulose and N, N＇-methylenebisacrylamide could reach 38.06%.
