The solubility of gases and vapors in miscible polymer blends, in the glassy state, has been considered. The sorption isotherms are calculated through the extension to polymer blends of the NELF model, for non swelling as well as for swelling penetrants. The swelling coefficient for the blend is given in terms of the swelling coefficients for the pure polymers. In all cases, the isotherms for the polymer blends can be completely predicted based on the parameters needed for the solubility in the pure polymer. The comparison between the model predictions and experimental data available for PS-TMPC blends are shown in detail and indicate the reliability of the model.

Abstract

The solubility of gases and vapors in miscible polymer blends, in the glassy state, has been considered. The sorption isotherms are calculated through the extension to polymer blends of the NELF model, for non swelling as well as for swelling penetrants. The swelling coefficient for the blend is given in terms of the swelling coefficients for the pure polymers. In all cases, the isotherms for the polymer blends can be completely predicted based on the parameters needed for the solubility in the pure polymer. The comparison between the model predictions and experimental data available for PS-TMPC blends are shown in detail and indicate the reliability of the model.
