Abstract

This study tested the hypothesis of a non-uniform size distribution of free volume by photoisomerizing photochromic probes in atactic polystyrene films. To determine the maximum amount that free volume would decrease from a reduction in expansion free volume of the glass at a temperature below its T//g, the study also found the equilibrium specific volume of polystyrene below its T//g by measuring the partial volume of polystyrene in athermal solvents.
