In this paper

the effect of different concentrations of NaCl on rheological properties of the hydrophobic associating polymer/SDBS systems was studied. The results show that different NaCl concentration has vary on the role model of the polymer/surfactant systems

when at low NaCl concentration

the thickening amplitude is SDBS concentration of 0〜100mg/L

the maximum growth multiple of viscosity is 5. 665

and as the addition of NaCl

thickening amplitude increases; when the middle NaCl concentration

which viscosity-increasing section increases with increasing NaCl concentration

However

the magnitude of increase in viscosity rapidiyrapidly decline with increasing NaCl concentration

the biggest growth multiple is 3. 100; And high NaCl concentrations

the system is also found thickening

thickening zone widens by the addition of NaCl

viscosity stable value also increases. Rheological and fluorescence experiments further provide the influence of the interaction at different NaCl concentrations on the polymer/surfactant systems

addition of NaCl was found to enhances the polymer/surfactant systems interaction and promotes form mixing aggregates of the polymer/ surfactant; also found high concentrations of NaCl affect the SDBS solubility

thereby affecting the the polymer/surfactant systems interactions.
