Abstract

We report that the pressure coefficient of the glass transition temperature, $d T_{g}$ / $d p$ , which is commonly used to determine the pressure sensitivity of the glass transition temperature $T_{g}$ , can be predicted in the thermodynamic scaling regime. We show that the equation derived from the isochronal condition combined with the well-known scaling, $T V^{γ}$ $=$ const, predicts successfully values of $d T_{g}$ / $d p$ for a variety of glass-forming systems, including van der Waals liquids, polymers, and ionic liquids.
