Abstract
|
We report that the pressure coefficient of the glass transition temperature, dTg/dp, which is commonly used to determine the pressure sensitivity of the glass transition temperature Tg, can be predicted in the thermodynamic scaling regime. We show that the equation derived from the isochronal condition combined with the well-known scaling, TV· = const, predicts successfully values of dTg/dp for a variety of glass-forming systems, including van der Waals liquids, polymers, and ionic liquids. ©2012 American Physical Society
