## Abstract Summary: An advanced isoconversional method has been applied to determine the effective activation energies (__E__) for the glass transition in polystyrene (PS), poly(ethylene terephthalate) (PET), and boron oxide (B~2~O~3~). The values of __E__ decrease from 280 to 120 kJโ€‰ยทโ€‰mol^โˆ’1^ in

## Abstract **Summary:** Variations of the effective activation energy __E__ of glass transitions have been determined by applying an isoconversional method to DSC data on the glass transition in PVC, PBMA, PVP, and PEN. A variability parameter ฮ”~__E__~ has been introduced to characterize the rate
