摘　　要：以水为分散介质,以丙烯酰胺(AM)、丙烯酸(NaAA)、丙烯酸羟丙酯(HPA)为共聚单体,甲基丙烯酸缩水甘油酯(GMA)为交联单体,通过自由基聚合制得新型水凝胶。考察了各单体用量对水凝胶吸水性能的影响,发现AM∶NaAA∶HPA摩尔比为0.5∶2∶1,GMA用量为1 wt%,水凝胶吸水倍率达到410 g/g。用红外光谱对水凝胶的结构进行了表征。New hydrogels were prepared by copolymerization of acrylamide （AM） , sodium acrylic （NaAA）, hydroxypropyl acrylate（HPA） and glycidyl methacrylate（GMA）via a free radical polymerization method in water. The swelling ratio of hydrogels depended on the chemical composition of the hydrogel. It was found that when the molar ratio of AM：AA：HPA was 0.5：2：1, and the amount of GMA. was 0.10 g, the swelling ratio reached 410 g/g. The hydrogels were characterized by IR spectra.
