摘　　要：由丙烯酰胺和N-苯基对烷基丙烯酰胺采用水溶液自由基胶束聚合法合成疏水缔合聚合物PBAM。研究了共聚物浓度、盐浓度、温度及表面活性剂浓度对共聚物溶液粘度的影响。结果表明,当聚合物的浓度大于临界缔合浓度时溶液的粘度急剧增加;NaCl的加入使得溶液的粘度下降,但适当结构的聚合物表现出较好的抗盐能力;聚合物浓度恒定时,溶液粘度随表面活性剂SDS浓度的增加急剧增加,达到最大值后迅速下降。聚合物稀溶液的流变行为呈现牛顿流体的性质。Nonionic PBAM water-soluble hydrophobically associating polymers has been prepared by micellar free radical copolymerization of acrylamide (AM), N-arylalkyl acrylamide. The effects of copolymer concentration, salt concentration, temperature, surfactant concentration and shearing on the apparent viscosity of copolymer have been studied. The results show that the solution viscosity increases sharply when the concentration of copolymer is higher than critical associating concentration (C~~__P); the viscosity of dilute solution of polymer decreases when NaCl is added, but that of semi-dilute one increases; The viscosity of copolymer solution has a maximum value as a function of sodium dodecyl sulfate (SDS) added. The polymer dilute aqueous solutions were Newtonian.
