Abstract: The interaction between polyacrylamide (PAM) and sodium dodecyl sulfonate (R_(12)SO_3Na) in NaCl solution and in NaCl-R_4OH solution have been studied by viscosity measurements. The electro-viscous effect was found, that is, the reduced viscosity of PAM-R_(12)SO_3Na solution increases with the decrease of the concentration of PAM. These results are interpreted in terms of the formation of polymer-micelle aggregate formed by the binding between the PAM and the R_(12)SO_3Na micelle.

Key words: Polyacrylamide, Sodium dodecyl sulfonate, Reduced viscosity, Electro-viscous effect
