摘　　要：以丙烯酰胺(AM)、2-丙烯酰胺-2-甲基丙磺酸(AMPS)及甲基丙烯酰氧乙基二甲基十二烷基溴化铵(AQ12)为原料,采用水溶液聚合法制备系列三元丙烯酰胺共聚物。正交实验确定最佳反应条件:反应温度5℃,引发剂浓度0.05%,单体质量浓度20%。用傅里叶变换红外光谱仪和核磁共振仪确证了三元共聚物的结构。聚合物的溶液性质表明,该三元共聚物具有一定的耐盐和抗温性能。Using acrylamide（ AM）,2-acrylamide-2-methyl propane sulfonic acid（ AMPS） and dimethyldodecyl（ 2-acrylamidoethyl） ammonium bromide（ AQ12）,a series of acrylamide terpolymers were prepared by aqueous solution polymerization. The optimum reaction conditions were determined by orthogonal experiment as follows： reaction temperature was at 5 ℃; the concentration of initiator was 0. 05%; the concentration of monomer is 20%. The structure of terpolymer were determined by Fourier transform infrared spectrometer（ FTIR） and Nuclear magnetic resonance（1H NMR）. Properties of polymer solution indicated that the series of terpolymers possessed salt-tolerant and heat-resisting performances.
