采用2-丙烯酰胺基-2-甲基丙磺酸（ AMPS）与丙烯酸十八酯（ SA）、丙烯酰胺（ AM）通过自由基胶束共聚法合成疏水缔合聚合物P（ AM-AMPS-SA）。经红外和核磁共振表征聚合物结构，并测定在不同剪切速率、NaCl、CaCl2浓度及温度条件下的聚合物溶液表观黏度的变化以及聚合物溶液的临界缔合浓度。结果表明，所制备的疏水缔合聚合物P（AM-AMPS-SA），它的临界缔合浓度在0.25~0.3 g/dL，具有一定的抗温、抗盐性以及抗剪切性，且对二价盐的抗盐性比一价盐要好。

Using 2-acrylamido-2-methyl propane sulfonic acid( AMPS)and stearyl acrylate( SA)and ac-rylamide( AM),then synthesized the hydrophobic associating polymer P( AM-AMPS-SA)by the micellar free radical copolymerization method. Using infrared and 1 H NMR to characterize the structure of the poly-mer. Measured the change of the apparent viscosity of polymer solution at different shear rate,concentra-tion of NaCl,CaCl2 and temperature,and the critical associating concentration of polymer solution. The re-sults showed the critical association concentration of polymer P( AM-AMPS-SA)is about 0. 25~0. 3 g/dL and the polymer have a certain temperature resistance,salt resistance and shear resistance,besides,the salt resistance in divalent salt solution is better than in the monovalent salt solution.
