      abstract     = {We use grand-canonical-ensemble self-consistent field
                      theory to study blends of both moderately and strongly
                      segregated homopolymers A and B with some diblock copolymer
                      AC, where C is attracted to B. We derive an analytical
                      condition for the Flory-Huggins interaction parameters,
                      which describes a balanced copolymer surfactant AC. We then
                      calculate ternary phase diagrams mainly for blends
                      containing such balanced surfactants. Among the ordered
                      structures, we generally consider lamellar and hexagonal
                      phases, whereas cubic phases are included in the calculation
                      when the polymer blends are studied far from the Lifshitz
                      point. The resulting phase diagrams are highly asymmetric.
                      In particular we show that even a compositionally symmetric
                      polymer blends - that is with equal concentrations and
                      molecular weights of the two homopolymers and with identical
                      polymerization degrees of the copolymer blocks - may
                      organize into either of the two distinct hexagonal
                      structures, as well as into the lamellar structure. One of
                      these hexagonal phases, with the B-rich matrix, has a rather
                      low content of the stabilizing copolymer and may therefore,
                      under experimental conditions, disorder into a polymeric
                      microemulsion. Overall we conclude that the AC diblock can
                      provide a slightly more efficient compatibilizer than its AB
                      counterpart, provided that the incompatibility of
                      homopolymers A and B is not too strong.},
