摘　　要：本文用￣（６０）Ｃｏ－ｙ射线辐射合成了聚（丙烯酰胺－丙烯酸钠）Ｐ（ＡＭ－ＮａＡ）智能性共聚物水凝胶，并用ＦＴＩＲ对共聚物进行了表征。着重研究了水凝胶在丙酮－水介质中的溶胀和收缩速率、溶胀平衡时间及体积相转变特性。Intelligent P(AM-NaA)(Polyacrylamide-sodium acrylate) copolymer hydrogel was synthesizedby ￣(60)Coy-Y ray radiation polymerization in aqueous solution,and the copmposition was studiedby FTIR spectrograph.The initial swelling and shrinking rates,the swelling equilibrium time and theproperty of volume phase transition of the copolymer hydrogel in acetone-water solutions of different concentrations were further investigated.

关 键 词：智能性 水凝胶 溶胀速率 P(AM-NaA)
