Abstract

The critical micellar concentrations (CMC) of sodium dedecyl sulfate (SDS) in aqueous poly(vinyl pyrrodine) (PVP) (M.W. 40000) solutions have been determined at different temperatures. The CMC of SDS increases with increase in concentration of PVP and decrease with increase of temperature. The critical aggregation concentration (CAC) and polymer saturation point (PSP) decrease with increase in temperature. The effect of the increase in polymer concentration of CAC and PSP has been determined. The thermodynamic quantities associated with the PSP are computed.
