| 摘 要： | 以丙烯酰胺 (AM)、丙烯酸甲酯 (MA)和α 丙烯酰胺基 α 甲基丙磺酸 (AMPS)为原料 ,通过水溶液共聚 ,合成了一种新型三元共聚物 (AM -MA -AMPS) ,并对其进行了表征。DSC和TG测试表明该三元共聚物的玻璃化温度为 2 45℃ ,分解温度为 381 8℃ ,均高于聚丙烯酰胺 (PAM)。实验表明 ,质量浓度为 2 0kg m3 的AM -MA -AMPS三元共聚物的水溶液黏度为 2 1 0 6mPa·s ,标准复合盐溶液黏度为 7 36mPa·s ,均较相应的PAM有提高。

| Abstract: | A new copolymer of acrylamide(AM),methyl acrylate(MA) and 2 acrylamido 2 methylpropanesulfonic acid (AMPS) was synthesized and characterized in aqueous medium.The results of DSC and TG show that the copolymer has glass transition temperature of 245 ℃ and thermal decomposition temperature of 381.8 ℃,both of which are higher than that of polyacrylamide(PAM).Other evidences also show that the viscosity of the copolymer solution (2.0 kg/m\+3) is 21.06 mPa·s,and the viscosity of the copolymer salt solution is 7.36 mPa·s,both of which are better than that of PAM. |
