Sažetak
The glass transition region of novolac phenol formaldehyde resin was investigated by integral and partial thermally stimulated depolarization current. The analysis of the activation energy vs. temperature showed three relaxation stages. Each stage was characterized by the relaxation map and compensation temperature. The midle stage compensation temperature coincided with the glass transition temperature. A model was proposed for unification of glass transition temperature and compensation temperature. For this purpose, an additional activation energy had to be introduced which was considered as the measure for the rigidity of the investigation system.
