摘　　要：通过丙烯酰胺(AM)与N-苄基-N-十二烷基丙烯酰胺(BDAM)反应,采用自由基胶束共聚后加减水解法合成了双尾疏水缔合三元共聚物(AM-NaA-BDAM).用FTIR红外光谱表征了聚合物的结构,并研究了共聚物溶液的流变性能及影响因素.实验结果表明:随着共聚物浓度的增加,在临界缔合浓度以上,表观黏度迅速增加,表现出明显的疏水缔合行为;共聚物溶液具有良好的黏弹性,G′(储能模量)>G″(损耗模量),且共聚物具有较强的耐温抗盐能力.A novel hydrophobically associating terpolymer（AM-NaA-BDAM） was prepared by free radical micellar polymerization and post-hydrolysis of acrylamide（AM）,N-benzyl-N-dodecylacrlyamide（BDAM）,and characterized by FTIR.The rheological behaviours of the copolymer solution were studied and the results showed that the apparent viscosity increased with the increasing of polymer concentration,when above the critical associating concentration,the apparent viscosity increased sharply,which indicated the forming of hydrophobical association in solution.The copolymer solution has good viscoelasticity,storage modulus（G′）〉 loss modulus（G″）.The copolymer also exhibited good abilities of temperature resistance and salt tolerance.
