| Abstract: | Experiments on surface tension in aqueous solutions of HPC as function of concentration and temperature were carried out. The temperature dependence of cmc is used to calculate the enthalpies and entropies of micelle formation for HPC, the enthalpy-entropy compensation plot exhibits an excellent linearity. The compensation temperature T_c is 298.06K. |
