Abstract

A model for non-Fickian gradient diffusion in polymer-penetrant systems is studied to assess its capability in predicting experimental results in weakly non-linear differential vapor sorption experiments at conditions where 'two-stage' sorption kinetics occur. The effects of six dimensionless parameters in the model on predictions of sorption kinetics are evaluated systematically by numerical simulations. The model predicts a number of observable trends. The predictions are compared successfully with sorption data of acetone vapor in VECTRA®, a glassy random copolyester of p-hydroxybenzoic acid and 6-hydroxy-2-naphthoic acid (HBA/HNA). The results are relevant to the application of VECTRA® and related polymers as barrier materials.
