Abstract: The diffusive behavior of pure and mixed 13CO2, methane, and ethylene in poly(4,4′-hexafluoroisopropylidene diphthalic anhydride-2,3,5,6-tetramethyl-1,4-phenylenediamine) membranes is investigated using a pulsed gradient spin echo NMR method. Also, proton and 13C spin–lattice and spin–spin relaxation times… read more here.
