摘　　要：以线性环糊精聚合物(PCD)与甲基丙烯酸缩水甘油酯(GMA)的反应制备可光聚合的PCD-g-GMA大单体,再加入不同量的共单体丙烯酸及丙烯酰胺,采用光聚合技术制备pH敏感水凝胶。本文对水凝胶的溶胀性能进行了测试,并初步探讨了对甲基橙及碱性品红的吸附性能。结果表明:该凝胶具有PH快迅响应及能更好的包合碱性品红染料。In this paper,a new kind of the（PCD/AAm/AA） hydrogels based on linear polymer cyclodextrin and Glycidyl methacrylete（GMA）were synthesized by photopolymerization.The swelling of PCD/AAm/AA hydrogels was examined,and we discussed the adsorption of Methyl orange（MO） and fuchsin basic for the hydrogel.Experiment results showed that pH,and gel with the AA content increases,the water swelling larger;with increasing pH,gel,water gel on the adsorption quantity of fuchsin large,on a Basic orange adsorption has little effect.Which demonstrates that the synthesis gel on the adsorption of cationic dyes better.
