“…Wittmer et al [3] also suggested that a ternary azeotrope exists only when at least one binary azeotropic composition is found among the three constituent binary pairs. However, Ring [5] contested this suggestion and claimed this not to be a prerequisite for having ternary azeotropes. Subsequently, Ham [6] suggested that terpolymer azeotropes may not exist and also pointed out that the Tarasov et al [2] approach was based on an incorrect condition among the binary reactivity ratios.…”

This work aims at presenting a general approach to locate azeotropic points in multicomponent polymerizations. Typically, for azeotropy studies in ternary systems, the literature is dominated by graphical solutions which may only be approximate. The approach consists of obtaining an azeotropic composition through a direct numerical solution of the relevant terpolymerization composition equations. The numerical approach is capable of locating the correct azeotropic composition for any ternary or multicomponent system, if such a point exists, and is illustrated via three case studies. Compared to prior efforts for azeotropic composition calculations in the literature, the presented numerical approach can be considered as general, direct, reliable, and more straightforward.

“…Considering the systems in which such azeotropes are absent, no one containing a three-component azeotrope were found [125]. Later [138,137] a possibility of the existence in principle of such systems was shown and also the necessary and sufficient conditions of their realization were formulated [6].…”

The terpolyrnerization equations of Alfrey-Goldfinger and Ring for calculation of ternary azeotropes are compared. I t is shown that the equation of Alfrey and Goldfinger can be transformed into that of Ring. Possible copolymerization ratios for the existence of ternary azeotropes without a binary one are discussed. Copolymerization ratios taken from literature show that there is a chance to find such an azeotrope, but an existing example was not found. So copolymerization ratios were arbitrarily chosen to give a range wherein such an azeotrope could exist.
