| Abstract: | The solubility and diffusion of propane in rubbery blends of polystyrene and poly(vinyl methyl ether) were investigated at low diffusant pressure. Solubibity is characterized by Henry's law and diffusion by Fick's law with concentration-independent diffusion coefficients. The composition dependence of the solubility and diffusion parameters is presented. The diffusion coefficients for propane in the blends are related to those for the component polymers by using the glass transitions as reference temperatures. |
