A relationship between the glass transition temperature and the conversion degree in the curing reaction of the EPY® epoxy system

M. Urbaniak

Abstract

There has been studied correlation between the glass transition temperature (Tg) and the conversion degree (α) in the cure reaction of the EPY® epoxy system (applied for machine foundation chocks), following evaluation of both these parameters. Three model correlations of Tg = ƒ(α) developed from DiBenedetto equation by Pascault and Wiliams, by Oleinik and also by Hale were verified. It was proved that the latter model best fits the experimental results Tg versus a obtained with the differential scanning calorimetry (DSC) method.
