ON THE UNIVERSAL SCALING OF THE DIELECTRIC-RELAXATION IN DENSE MEDIA

We reconsider the idea of the universal scaling of the alpha relaxatio n and point out what is the cause of the recent controversy concerning this concept. A necessary condition the scaling relationship has to f ollow is presented. Consequently, we suggest that a generalized scalin g relationship, which is potentially able to account for the dielectri c relaxation of low-molecular-weight as well as polymeric glass-former s, is likely to be established. The generalized scaling plot for the l iterature experimental data of several glass-forming systems (low mole cular weight and polymeric) is presented.
