VOLUME RECOVERY AND THE TAU-EFFECTIVE PARADOX

摘要

Volume recovery experiments on polystyrene and on an epoxy glass have been made.The experiments on the polystyrene involved novel temperature perturbations which allowed us to obtain the relaxation time as a function of volume during aging.The experiments on the epoxy were performed to investigate the tau-effective paradox.Both sets of experiments indicate that the relaxation time does not depend on the instantaneous volume as assumed in models of structural recovery.
