Abstract

New measurements have been conducted for the volume recovery of polycarbonate in up and down jump experiments using a classical mercury dilatometer. The data were analyzed using a hybrid Tool-Narayanaswamy-Moynihan-KAHR model. The results of the down-jump experiments were compared prior to physical aging experiments. It was found that, consistent with prior work on epoxy in down-jump experiments near the glass transition, the volume continues to evolve even after the viscoelastic relaxation response has attained apparent equilibrium.
