The physicochemical behavior of mixtures containing polymers and surfactants is of increasing interest, because of their relevant capacity as viscosity modulators, of their ability to control surface adsorption, and of their solvent capacity toward fats and oils [1]. Inters is focused here to new generation surfactants, the Gemini they consis in two alkyl chains, two polar heads are joined together by spacers. The cationic Gemini surfactants used in this work α, ω-(CmH2m+1 n+ (CH3)2)2 (CH2)5 (Br-) 2 are referred to as m-s-m, where m and s are numbers of carbons of the tails and spacer alkyl chains, respectively. The polymer examined in this work is poly (ethylene glycol). These polymers are known to self aggregate in solution and therefore are also good candidate to potentially enhance the interaction between polymer and cationic surfactant [1].The surface tension ,γ ,plots of polymer-surfactant systems normally display three points where the surface tension changes quite sharply ,designated T1,T2 and T3. T1 is the low-concentration end ofthe first plateau and is typically referred to as the critical aggregation concentrations(CAC) for the system.T2 is the onset of another plateau in the surface tension at high surfactant concentration and corresponds to the critical micelle concentration for the formation of pure surfactant micelles (CMC). T3 is generally less well defined, but is considered to the surfactant concentration where the bulk polymer is saturated with surfactant aggregates. Any further surfactant added to the solution cannot bind to the polymer and can therefore lower the surface tension until in micellizes at T3 [2]. The purpose of this study was to investigate whether any interaction occurs in aqueous solution between a novel class of cationic surfactant and a neutral polymer.To our knowledge only a few previous study of surfactant-polymer interactions has been performed using Gemini surfactants. The results of this study show that polymer/cationic Gemini surfactant complexes are formed these systems.
