Notes:
A modified fluid-lattice model for mixtures of fluids is presented. Expressions for the basic thermodynamic quantities of mixing are given. From the equation for vapor-liquid equilibrium, the expression for the Henry constant at low pressure is derived. Weight fraction Henry constants for gas-polymer and gas-polymer-polymer systems are derived as limiting cases. Predictions of theory about the effect of temperature on the Henry constants are compared with experimental data for twenty two polymer-organic vapor systems. In almost all cases the Henry constants are reproduced within the limit of experimental error. The effect of pressure on gas solubilities is considered. The effect of polymer-polymer binary interaction parameter on the Henry constant in a gas-polymer-polymer mixture is also discussed.
