This paper describes methodologies that have been developed for studying the physical aging of free-standing thin polymer films and its effect on gas permeability. Both solution casting and spin coating methods were used to obtain thin polysulfone films having thicknesses in the range of 400-1000 nm

## Abstract A method of moments has been formulated for the determination of the diffusivity of a gas in a polymer from a step response in a continuous permeation chamber. Contributions of system components other than the polymer are easily factored out to determine the contribution of the polymer
