During the past year the Center's research activities have continued, of course, to focus on the solubility and diffusivity of solvents in polymers at various conditions. We have continued to apply our tried and proven techniques: inverse gas chromatography, gravimetric sorption balance, and pressure decay. We have also done some work with the more recent high-pressure capsule apparatus. In addition we have expended considerable effort to upgrade and expand the offerings on our web site.
