The NET-GP model was combined with a simple rheological constitutive equation to build a sorption-diffusion-relaxation model able to describe mass uptake and swelling kinetics of polymeric films in contact with carbon dioxide over a wide range of pressures and temperatures. The model calculations are compared with data on mass sorption kinetics for CO2 in supported glassy poly(methyl methacrylate) (PMMA) films, measured in a high-pressure quartz crystal microbalance (QCM).}, number={8}, journal={INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH}, author={Carla, Vito and Hussain, Yazan and Grant, Christine and Sarti, Giulio C. and Carbonell, Ruben G. and Doghieri, Ferruccio}, year={2009}, month={Apr}, pages={3844–3854} }

This study utilizes the quartz crystal microbalance (QCM) to monitor and evaluate the dissolution of poly(1,1-dihydroperfluorooctyl methacrylate- r -2-tetrahydropyranyl methacrylate), poly(FOMA- r -THPMA), polymer films in supercritical CO 2 over a range of temperatures and pressures. Polymer dissolution rates at the range of pressures studied were evaluated to quantify the dissolution kinetics for the polymer. The experiments revealed that the polymer dissolution in supercritical CO 2 undergoes two apparent processes: a rapid absorption of CO 2 into the polymer film followed by a gradual dissolution of polymer film into the CO 2 at the polymer–CO 2 interface. The nature of these interfacial phenomena and their associated effect on the rate are discussed.}, number={2}, journal={JOURNAL OF SUPERCRITICAL FLUIDS}, author={Hussain, Yazan and Wu, You-Ting and Ampaw, Paa-Joe and Grant, Christine S.}, year={2007}, month={Sep}, pages={255–264} }

The model presented is an extension of the nonequilibrium thermodynamics for glassy polymers (NET-GP) approach, modified to allow for the calculation of the effects of pressure, temperature, and gas concentration on the glass transition. Mass sorption and one- dimensional swelling behavior are analyzed for the carbon dioxide (CO2)-poly(methyl methacrylate) (PMMA) system at high pressure.
