Abstract
Although theories of glassy polymer relaxation use assumed dimensionless size distributions of local free volume, experimental verification is still lacking. The purpose of this study is to measure the size distribution of local free volume in glassy polymers such as polystyrene using photochromic molecular probes. This study differs from the recently reported studies in that a variety of photochromic molecules capable of probing a wide range of sizes of local free volume are being employed.
