Abstract

Physical ageing results from the slow contraction towards equilibrium of a non-equilibrium amorphous material cooled from above the glass transition to below it. It has been well established that, under isothermal conditions, the gradual volume change of the glass is accompanied by changes in its viscoelastic properties. The objectives of the present work are twofold: 1) to characterize the volumetric and viscoelastic ageing responses in asymmetry experiments and, 2)to analyze quantitatively the time scale question in both up-jump and down-jump approaches towards equilibrium.
