Abstract

By using differential scanning calorimetry, kinetic and thermodynamic measures of the glassformer property "fragility" were made for a glassformer that permits both glass transition and fusion to be observed. For a series of glassformers covering the F1/2 range from 0.5 up to 0.8, the thermodynamic and kinetic measures of fragility were again found to be similar.
