Predictive scheme for simultaneous evaluation of the modulus, yield (or tensile) strength and gas permeability of heterogeneous polymer blends is used to estimate the effects of the phase duality interval delimited by the critical volume fractions of components. The scheme combines a two-parameter equivalent box model and the data on the phase continuity rendered by modified equations of the percolation theory.
