Acrylamide(AM)/Octadecyl methacrylate(OM) hydrophobically associating water-soluble copolymer were synthesized by free-radical micellar copolymerization.The copolymer structures were determined by FT-IR spectroscopy.The effects of copolymer concentration,salt concentration,rate of shear and temperature on the apparent viscosity of the copolymer have been studied.The results showed that the solution apparent viscosity increase sharply when the mass fraction of the copolymer was higher than critical associating concentration(2%).With an increasing of NaCl concentration,the copolymer solution apparent viscosity increased.
