Аннотация:The microphase separation in the incompressible melt of a diblock copolymer the macromolecules of which are comprised of a linear A-block and a three-arm star-like B-block is studied. The phase diagrams of the melt was constructed at various values of the chemical structure parameters of macromolecules for both the monodisperse and polydisperse variants of the model. In the latter case, the number of monomer units in the linear block is described by the Flory distribution. In comparison with the monodisperse variant, the polydispersity of macromolecules in the melt leads to increases in the temperature of transition to an ordered state and in the period of the mesophases of melt and substantially changes the positions of the boundaries of stability of the mesophases.
