Fundamental thermodynamic properties such as gas solubility are                 measured at pressures up to 1000 psia for both components in several            gas/polymer binary mixtures.  The systems to be studied are either              important in engineering applications or have been chosen for their             specific physical properties to determine the effects of size and               polarity on polymer-penetrant interactions.  Typical systems may                include carbon dioxide, methane, ethane, nitrogen, polycarbonate,               polysulfone, and silicone rubber.  Direct determination of both gas             uptake and volume dilation of a penetrant-laden polymer sample are              performed using equipment previouly developed.  The equipment allows            actual measurement of changes in film sample dimensions in all three            coordinate directions as a function of gas pressure.  A video-assisted          micrometry system is used to measure the changes in the film thickness,         while a precision cathetometer system provides the measurements of the          length and width dimensional changes.
