Classification of glass-forming liquids based on the dramatic change in their properties upon
approach to the glassy state is appealing, since this is the most conspicuous and often-
studied aspect of the glass transition. Herein, we show that a generalized scaling, log (τ)∝
T− 1 V− γ, where γ is a material constant, yields superpositioning for ten glass formers,
encompassing van der Waals molecules, associated liquids, and polymers. The exponent γ
reflects the degree to which volume governs the temperature and pressure dependence of …

The exponent reflects the degree to which volume governs the temperature and pressure dependence of the relaxation times.
