摘　　要：用烯丙基缩水甘油醚对β-环糊精进行改性,得到含有烯丙氧基的β-环糊精(烯丙氧基-CD)。利用烯丙氧基-CD上的C=C双键作为反应基团,用反相乳液聚合方法,将其与2-丙烯酰胺-2-甲基丙磺酸(AMPS)及丙烯酰胺(AM)进行共聚合,制得烯丙氧基-CD/(AMPS-AM)共聚物。通过红外光谱和核磁共振谱对该共聚物进行了表征,并测定了其吸水性能。结果表明烯丙氧基-CD的用量对吸水倍率有一定影响,在不同盐水溶液中展现的吸水倍率也不同,其中在Na^(+)溶液中的吸水倍率相对较高。β-cyclodextrin was modified by allyl glycidyl ether to obtainβ-cyclodextrin containing allyloxy(allyloxy-CD).Using the C=C double bond on allylloxy-CD as the reaction group,the copolymerization with 2-acrylamide-2-methylpropanesulfonic acid(AMPS)and acrylamide(AM)was carried out by reverse phase emulsion polymerization to obtain allylloxy-CD/(AMPS-AM)copolymer.The copolymer was characterized by infrared spectroscopy and nuclear magnetic resonance spectroscopy,and its water absorption was determined.The results showed that the amount of allyloxy-Cd had an effect on the water absorption ratio,and the water absorption ratio was different in different brine solutions,among which the water absorption ratio in Na^(+) solution was relatively higher.
