| 摘 要： | 讨论了丙烯酰胺、3-丙烯酰胺-3-甲基丁酸钠和N-烷基丙烯酰胺三元共聚物(CAANA)的水溶液特性，并与部分水解聚丙烯酰胺(HPAM)水溶液特性相比较。芘荧光光谱分析和激光光散射仪测量结果表明。CAANA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，并使得CAANA在水溶液中具有较大的均方旋转半径，相对于HPAM，CAANA具有更好的耐温抗盐性能。在一定范围内，CAANA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。

| Abstract: | This paper studies the synthesis and characterization of the polymer (CNA) which is composed of acrylamide,3-acrylamide-3-methyl-butyric sodi um a nd N -alkyl acrylamide. By the pyrene fluorenetry and laser light scattering , the determinations show that inter-molecular hydrophobic association is formed a nd get the bigger hydrodynamic radius. The CNA is better temperature-tolenc e and salt-resistence than the HPAM. In definite range, the hydrophobic associat i on is more stronger, the characters of temperature-tolence and salt-resisite nce is more better. |
