Abstract :
The author present results from an experimental study on binary polar-nonpolar mixtures (propylene carbonate-toluene) from ambient down to their glass transition temperatures. The values of static permittivity and dielectric relaxation time obtained made it possible to estimate the temperature dependence of dipole moment and the Kirkwood correlation factor of propylene carbonate as well as the molecular relation time of toluene (or methylbenzene)
