Sorption of vapour mixtures of methanol and dimethyl carbonate in PDMS: Experimental study

Original language description

We report an original experimental method for the characterization of the sorption of binary vapour mixtures in polymers. Measurements of sorption of vapour mixtures can reliably identify and quantify the cooperative and competitive sorption, which can limitedly be predicted from the data on sorption of pure components, and on which scarce data are available. The method combined the sorption gravimetry and the analysis of sorbate using Fourier-transform infrared spectroscopy. The sorption of binary vapour mixtures of methanol and dimethyl carbonate in cross-linked poly (dimethylsiloxane), PDMS, was measured at 40 oC. A clear cooperative sorption effect of dimethyl carbonate on methanol was observed. To effectively parameterize the sorption of the vapour mixtures in the polymer, an extension of Guggenheim Anderson de Boer (GAB) model was derived. Overall, the proposed method represents a feasible way of measuring the sorption of mixtures of vapours in polymers.
