Herein, the aggregation manner of the mixture of polyvinyl alcohol (PVA) and tetradecyltrimethylammonium bromide (TTAB) was performed in polyols (glucose, maltose and galactose) media over 300.55–320.55 K temperatures range with 5 K interval through conductivity measurement method. The micelle formation of TTAB + PVA mixture was identified by the assessment of critical micelle concentration ( CMC ) from the plots of specific conductivity ( κ ) versus TTAB concentration. The degree of micelle ionization ( α ), the extent of bound counter ions ( β ) as well as thermodynamic properties (ΔG   m   0${\Delta}{G}_{m}^{0}$,ΔH   m   0${\Delta}{H}_{m}^{0}$andΔS   m   0${\Delta}{S}_{m}^{0}$) of TTAB + PVA systems have been estimated. The  CMC  values reveal that the micelle formation of TTAB + PVA mixture experience an enhancement in the manifestation of polyols. The values of free energy of micellization (ΔG   m   0${\Delta}{G}_{m}^{0}$) are negative for the TTAB + PVA system in aqueous polyols media, suggesting a spontaneous aggregation phenomenon. TheΔH   m   0${\Delta}{H}_{m}^{0}$andΔS   m   0${\Delta}{S}_{m}^{0}$values of TTAB + PVA systems direct that the PVA molecule interacts with TTAB through the exothermic, ion-dipole, and hydrophobic interactions. The thermodynamic properties of transfer were also determined for the move of TTAB + PVA mixture from H 2 O to water + polyols mixed solvents. The values of compensation temperature ( T   c ) and intrinsic enthalpy gain (ΔH   m0   ,   ∗${\Delta}{H}_{m}^{0,\ast }$) were evaluated and discussed for the studied system.
