The T sub ll Relaxation of Polystyrene.

Abstract

A review of recent work on a relaxation (T sub ll) above the glass transition (T sub g) of amorphous polystyrene is presented. On the basis of experimental data from torsional braid analysis (TBA), differential scanning calorimetry (DSC) and differential thermal analysis (DTA), and of an examination of the literature, it is suggested that T sub ll represents a molecularly-based transition.
