  • What is the rheological behaviour of aqueous solutions of polyacrylamide?
  • Rheological behaviour of aqueous solutions of polyacrylamide depicting the effect of temperature and concentration in the range of 5–45 °C and 0.25–0.6% wt/vol, respectively, was studied. Based on the observed experimental data, the following conclusions are drawn:
  • What is the shear sensitivity of polyacrylamide?
  • Shear sensitivity: At relatively low shear rates, aqueous solutions of polyacrylamide are pseudoplastic. However, at high shear rates rupturing the polymer chains can degrade the molecular weight. Solution Stabilityr The stability of the polymer can be improved by the addition of sodium thiocyanate, thiourea, sodium nitrite.
  • What is the cornplex viscosity of polyacrylamide aqueous solutions?
  • The cornplex viscosity of PAM solutions is shown in figure (4.6.6). Two different behaviors can be recognized. First it is clear those polyacrylamide aqueous solutions in concentrations between 2 - 5% exhibit strong shear thinning behavior up to the critical frequency.
  • Do AL1 concentrations of polyacrylamide solutions behave like viscoelastic material?
  • The results showed that al1 concentrations of polyacrylamide solutions behave like viscoelastic material, and the linear viscoelastic range for al1 concentrations has been detemined. The viscous parts were higher than the elastic parts, agreeing well with the results obtained by the dynamic test.
