Glass transition temperature predictions in some epoxy polymers

Abstract The glass transition temperature as an additive property was studied on a series of epoxy/amine crosslinked polymers. Various methods from the literature of analyzing the glass transition temperature in terms of components are presented and then judged to determine which of these methods gives the best agreement between calculated and measured glass transition temperature. It was found that predictions agree on the average with the measurements to within the accuracy of the measurements, approximately 3%.
