Abstract
Thermal analysis of the glass transformation permits the determination of the temperature at which the transformation occurs at a maximum rate. It is found that this temperature depends on the experiment's rate of warmup. Appropriate handling of kinetic equations and experimental data permits the evaluation of the thermodynamic functions that characterize the activation barrier. Experimental results on glycerol are comparable to results extrapolated from dielectric relaxation studies.Keywords
