Thermodynamic- Kinetic Correlations in Supercooled Liquids- A Critical Survey of Experimental Data and Predictions of the Random First Order Transition Theory of Glasses

Thermodynamics and kinetics are thought to be linked in glass transitions. The quantitative predictions of -relaxation activation barriers provided by the theory of glasses based on random first order transitions are compared with experiment for 44 substances. The agreement found between the predicted activation energies near Tg and experiment is excellent. These predictions depend on the configurational heat capacity change on vitrification and the entropy of melting the crystal which are experimental inputs.
