Diffusion and Molecular Interactions in a Methanol/Polyimide System Probed by Coupling time-resolved FTIR Spectroscopywith Gravimetric Measurements

In this contribution the diffusion of methanol in a commercial polyimides (PMDA-ODA) is studied by coupling gravimetric measurements with in-situ, time-resolved FTIR spectroscopy. The spectroscopic data have been treated with two complementary techniques, i.e. difference spectroscopy (DS) and least-...
