Program written for windows. Software product permits a user to construct the Miscibility Maps of systems of different types, proceeding from given values of the Flory-Huggins parameters. Hence this product offers a possibility not only to reveal the topology of the MM of a polymer blend, containing copolymers prepared by a polymerization of given monomers but also to determine quantitatively the boundaries of compatibility regions of any blend depending on composition of the copolymers involved. If you want to get any additional information on the ``Miscibility Maps'' or any other software products developed by us you may contact Semion Kuchanov at kuchanov@orc.ru.
