area of glasses applications. This can be realized in terms of the glass transition temperature ( T g ) and activation energy of glass transition ( E g ). Such activation energy is involved in the molecular motion and rearrangements of the atoms around

.613 Thermal curing The thermally curable samples were cured at different heating rates (2, 5, 7.5, 10, and 15 °C min −1 ) with a Mettler DSC-822e calorimeter from 0 °C to 250 °C. The ultimate glass transition temperature of the cured materials ( T g
