Some indicators of tricomponent polymer mixtures are investigated in dilute solution, in concentrated solution, and in the solid state. The method used is that of simplex Lattice planning of the experiment for an experimental mathematical description of these indicators of the composition of polymer mixtures. The dependences are described by regression equations of the fourth power. Lines of equal values are constructed of the investigated indicators, according to the equations obtained. The character of the outline surfaces corresponds to the complex interaction between the supramolecular formations in the transitions from a dilute into a concentrated solution and in the solid state. Compositions of optimum regions were determined wherein films and probably fibers of optimum physicomechanical indicators can be obtained. These optimum regions outline the zones of improved structural compatibility among the components.
