A simplifying version of the lattice cluster theory is formulated for binary random copolymer A x B 1‐x /A y B 1‐y blends. The underlying model is based on united atom structures for the individual monomers of A and B species. Applications of the theory to saturated poly(butadiene) blends display only semiquantitative agreement with experiment. We discuss possible routes to theoretical improvements and experiments that would be helpful in testing theory.
