摘要
Solubilities and diffusivities of CO//2 and CH//4 in aromatic polyesters generated from independent sorption and permeation measurements at 35 degree C and up to 25 atm, are compared. Less than 21% change in the glass diffusivity was observed. The data are interpreted qualitatively in terms of changes in the calculated packing density, chain torsional mobility of the polymer, and gas-polymer attraction.
