Predictions of Onset of Crystallization from Experimental Relaxation Times I-Correlation of Molecular Mobility from Temperatures Above the Glass Transition to Temperatures Below the Glass Transition

摘要

Predicting onsets of crystallization at temperatures below T g, from data above T g, would require that the correlation between crystallization onset and mobility is same above and below T g, and the techniques being used to measure mobility above and below T g are measuring essentially the same kind of mobility. The aim of this work is to determine if the relaxation times obtained using different techniques (DSC, TAM) below T g correlate with relaxation time obtained above T g using dielectric spectroscopy.
