Notes:
A simple model for the free energy of mixing of compressible polymer blends is derived, based on the regular solution model. Its ability to predict phase behavior for weakly interacting polymer pairs using only the pure component properties of mass density, solubility parameter, and thermal expansion coefficient is illustrated for mixtures of polystyrene and poly(n-alkyl methacrylates) with n≤12. The model yields a clear explanation for the strong pressure effects observed in some of these systems, including the first reported baroplastic elastomer. © 2001 American Institute of Physics.
