| Abstract |
Thermally Stimulated Depolarization Current (TSDC) measurements on 4,4 -methylenebis (N,N-diglycidylaniline) (NMDA) have been carried out in the temperature region from - 165 degrees C (108 K) up to 0 degrees C (273 K). The slow molecular mobility was characterized in the glassy state and in the glass transformation region. Important discrepancies were reported in the value of the steepness index or fragility (T-g-normalized temperature dependence of the relaxation time) obtained by different, and well established, experimental techniques. The influence of ageing on the measured TSDC current peaks has been discussed. (C) 2006 Elsevier B.V. All rights reserved. |
