摘要：A physico-chemical study of the hydrolyzed polyacrylamide (AD37) solution, using rheology and viscosity methods was reported. The viscosity of polyelectrolytes is measured in the presence effect of different additive (NaCl salt, N-dodecylp yridinium chloride surfactant (DPC) and poly(4-vinylpyridine). It was found that the DPC causes a larger reduction of the viscosity of AD37 solution than does NaCl. This difference is due to the presence of the second type of interaction with DPC (hydrophobic interaction). The DPC chains can bind to the polyion chain cooperatively in the form of the so-called (polymer-induced) micelles. The result shows also that the effects are greater in the presence of the P4VP. The contact between the polyelectrolyte (AD37) and the DPC surfactant or P4VP chains under the conditions used enables a variety of types of interaction, depending on the relative concentrations
