文摘

TR polymers and PIM are compared to the glassy polymer database. Analyze diffusion selectivity, solubility selectivity, diffusivity, and solubility. TR polymer and PIM do not have different transport mechanism than other polymers. TR and PIM maximize diffusion selectivity, diffusivity, and gas solubility. Gas diffusion diameters squared correlate linearly with diffusion coefficients.
