The Effect of Conformation Order on Gas Separation Properties of Polyetherimide Ultem Films
Changes of the spectral characteristics of absorption bands depending on the films’ treatment method were registered for polyetherimide Ultem films. The possibility of selection of structural criteria (the ratio of the functional groups absorption bands intensities) showing all conformational change...
