Interactions of Polyglycol Ethers with Anionic Surfactants in Water

In order to determine the thermodynamic properties of the aggregation process between sodiun dodecyl sulfate (SDS) and polyglycol ethers (PEG) with average molar mass 35000, 20000, and 10000, the temperature dependence of polymer-surfactant nteraction is used. Surface tension, ionic conductivity, and solubilization methods have been used to quantify the interactions.It was found that the transfer of SDS micelles from aqueous media to aqueous polymer media is more feasible than the reverse. In addition, the hydropholic interaction seems to be important, as opposed to the charge-nonpolar type interaction.
