## Abstract Mass sorption/desorption and volume dilation/consolidation measurements are reported for tetramethyl and hexafluoro polycarbonate samples in the presence of carbon dioxide pressures up to 900 psia at 35Β°C. These results are combined with previous results for bisphenolβAβpolycarbonate. T
## Abstract Plasticization of poly(ethyl methacrylate) (PEMA) by CO~2~ is investigated by dielectric relaxation spectroscopy. The dissipation factor of a dielectric cell containing the film and air gaps is measured as a function of frequency (1β10,000 kHz) and CO~2~ pressure (0β60 atm) over the tem
