Abstract
The random phase approximation is summarized for compressible polymer blend mixtures in the homogeneous phase region. Similarities with the polymer reference site interaction model are described. The effect of compressibility is also discussed in terms of 'free volume' by introdu cing an extra component to represent 'small voids'. Variation oft he e ffective Flory-Huggins interaction parameter with composition is found to agree with results obtained using the lattice cluster theory.
