摘　　要：采用自由基胶束聚合法,合成了一种疏水缔合型丙烯酰胺-烷基丙烯酸酯共聚物。用1HNMR谱和TEM对该共聚物进行了表征。用旋转黏度计测定了不同疏水基含量的聚合物的溶液性能,考察了温度对聚合物溶液性能的影响,同时研究了外加盐对聚合物溶液形貌的影响。Hydrophobically modified polyacrylamide(P(AM/2-EHA)was synthesized. The copolymer structure was determined by ()~1HNMR spectroscopy. Characterization of polymer appearance by TEM showed that the polymer have a diameter of about 20~30nm. The apparent viscosity of solution and the influence of temperature on polymer solution were also discussed. The appearance of polymer with and without NaCl aqueous solution was also investigated.
