| Popis: | The inverse gas chromatography technique was applied to measure solubility and diffusivity in a ternary polymer−solvent−solvent system. This method requires the comparison of the experimental elution profiles with theoretically predicted ones. A new simplified model was developed to describe ternary systems. In addition, a new experimental apparatus was constructed to monitor the independent composition profiles during a multicomponent experiment. The model was evaluated using experimental data for the system poly(vinyl acetate)−toluene−tetrahydrofuran at 80 and 100 °C. Solubility and diffusivity of the mixed solvents in poly(vinyl acetate) were collected at 80°. |
