摘　　要：以丙烯酰胺(AM)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)和N-烷基丙烯酰胺(N-AAM)为单体,合成了AANA三元共聚物,并与部分水解聚丙烯酰胺(HPAM)相比较,讨论了三元共聚物(AANA)的水溶液特性。芘荧光光谱分析和激光光散射仪测量结果表明,AANA由于引入了疏水性单体,在水溶液中形成了分子间的疏水缔合作用,使得AANA在水溶液中具有较大的均方旋转半径,与HPAM相比,AANA具有更好的耐温抗盐性能。实验结果表明,AANA中引入的疏水性单体形成的缔合作用愈强,愈有利于改善聚合物的耐温抗盐性能。Terpolymer comprising acrylamide, 2 - acrylamido - 2 - methyl - 1 - propane sulfonic acid and N -alkylacrylamide was synthesized, and its performances in water were studied and compared with polyacrylamide. The terpolymer was characterized by pyrene fluorescent spectrometry and laser spectrum. The result showed that AANA had hydrophobic association intermolecularly in solution due to insertion of hydrophobia monomer into main chain of the polymer, thus had bigger hydrodynamic radius. The AANA had higher heat resistance and salt tolerance that HPAM.The stronger the association formed due to insertion of hydrophobic monomer, the better the heat resistance and salt tolerance.
