| Abstract: | A hydrophobically associating acrylamide copolymer(AM-NaA-BOAM) was prepared by radical micellar copolymerization using acrylamide(AM) and N-benzyl-N-octylacrylamide(BOAM) and characterized by Fourier transform infrared spectrum(FT-IR) and ~1H nuclear magnetic resonance spectrum(~1H-NMR).The rheological behaviors of the copolymer solution were studied and the results show that the apparent viscosity increases with the increase of polymer concentration,when above the critical associating concentration(600mg/L),the apparent viscosity increases sharply,indicating the forming of hydrophobical association in solution.The copolymer solution has good viscoelasticity,storage modulus(G’)>loss modulus(G").The copolymer also exhibits good abilities of temperature resistance and salt tolerance. |
