Abstract: Polymer-surfactant interaction studies by surface tension conductance, and viscosity measurements at various temperatures have been carried out between the non ionic polymer polyacrylamide (PAA) and cationic surfactant cetyl trimethylammonium bromide (CTAB). The critical aggregation concentration (CAC) and polymer saturation point (PSP) have been computed and are found to decrease with increase in temperature. The effect of the increase in polymer concentration on CAC & PSP has been determined. The degree of ionization 'α', of the polymer-surfactant complex is computed which is found to increase with increase in temperature. The thermodynamic quantities associated with the PSP are computed.
