中文摘要：

与线性聚合物相比,交联聚合物因其复杂的结构而具有特殊的性能[1～3].壳聚糖是甲壳素的N-脱乙酰基产物,具有良好的生物相容性、无毒性和生物可降解性等特点[4],在食品、医药及水处理等领域中广泛应用[5～7].在实际应用中,经常将各种单体接枝到聚合物表面,

英文摘要：

Cross-linking copolymerization of 2-acrylamide-2-methylpro panesulfonic acid（AMPS） and chitosan in ionic liquid was studied using ceric ammonium nitrate（CAN） as an initiator,p-benzoquinone as resistance polymerization retarder,and glycine hydrochloride ionic liquid water solution as reaction medium.The obtained product was characterized by SEM,FTIR and TGA.The results showed that,the reaction rate and grafting ratio were improved greatly by Cl as reaction medium.The obtained product was regular spherical,the particle diameter was about 2 μm.And the product had smooth surface,some resistance to acid and alkali.
