Summary A theory of inhomogeneous multicomponent polymer systems developed earlier by the authors is used to study the phase diagrams of a mixture of block copolymers, homopolymers and solvents. We assume that the deviation of the local volume fraction of any component from its average value is small, and we expand the free energy of the system up to fourth order in the fluctuations. This approach enables us to determine the spinodal boundaries and to estimate the location of the binodals. Some new features of the resulting polymeric phase diagrams are the prediction of eutectic points, similar to those observed in metallurgy, and the phenomenon of homopolymer-induced mesophase formation.
