Mixtures of polyxypropylene polyols with water are typical systems with a lower critical miscibility temperature whose position is proportional to the concentration of end hydroxyl groups independently of the degree of branching of the polyethers. Replacement of low-molecular products with water. The polydispersity of the specimens of the polyoxypropylene polyols has a substantial effect on the phase diagrams, whose shapes are principally determined by the presence of the high-molecular fractions.
