Abstract: The behavior of the viscosity of supercooled liquids with temperature has been extensively studied in different regimes. We present a universal behavior for the Logarithmic Shift Factor for fragile and polymeric glassformers in two temperature regions, above and below the crossover temperature Tc, respectively. We find two different equations, one for each region, that may be represented as master plots which show universal behaviors for both cases.
