Sažetak
Analysis of the course of glass transition in epoxy resin was performed by thermally stimulated depolarization current (t.s.d.c.) measurements. The methods used were the global method, the partial heating technique and the partial polarization technique. The investigation was carried out with pure resin, with resin containing admixtures and with cured resin. The results for maximum current Im, maximum temperature Tm and activation energy Ea of α peaks are slightly influenced by admixtures. Stepwise determination of Ea shows that the depolarization process is continuously distributed in all systems. The most pronounced changes are observed in the cured resin: Im and Tm are increased and Ea and the width of distribution ΔEa are significantly decreased.
