The magnitude of the activation energy for diffusion, ED. is shown to be inversely dependent on the fractional free volume of the polymer above Tg. From the proportionality of ED above and below Tg, the magnitude of El, below T, is also inversely dependent on the free volume in that temperature rang

## Abstract A new method has been developed to determine the probability of miscibility in binary polymer blends through hydrodynamic interaction. This is achieved by the measurement of the free volume content in blends of carefully selected systemsβ€”styrene acrylonitrile (SAN)/poly(methyl methacryl

The development of a new model for the diffusion of gas molecules in glassy polymers is presented which utilizes concepts from free volume theory and relies on a dual-mode interpretation of sorptive dilation in glassy polymers. Three assumptions are made in the development of the model. First, the f
