摘要：

The paper deals with the interactions between a cationic surfactant dodecyl tetrabromide (DTB) and polyethers containing variable mole fraction (tau) Of methyleneoxide units MO: (poly(ethylene oxide), PEO without MO, poly(1,3,6,9-tetraoxacycloundecane), PTGF with a MO fraction of 0.25 and poly(1,3-dioxolane) PDXL with a fraction of MO of 0.5. Conductivity measurements show weak interactions at a temperature T = 50 degrees C, while they are absent for the three polymers at room temperature. The solubility of PDXL which has a relatively lower critical solution temperature in water is improved by the presence of the surfactant. Besides, at T = 50 degrees C the viscosity increases upon addition of DTB. The association diagrams do not significantly differ for the three polymers which is very different from what was observed with an anionic surfactant.
