Abstract
The goal of this work was to prove that the phenomenon of cacervation was one of the phenomena of phase separation determined by the general laws of thermodynamic phase equilibrium. In this connection, the toluene–ethanol–polystyrene system, known from the literature to be capable of forming coacervates: was studied, and the binodial curve as well as a number of semiempirical coefficients necessary for its theoretical determination established experimentally. For the latter purpose use was made of a generalized form of Maron's equation for the thermodynamic potential of mixing. The experimental and theoretical data showed good agreement. It was therefore concluded that systems capable of forming coacervates are subject to the general laws of thermodynamic equilibrium, and formation of coacervates is a phenomenon within the limits of a simple phase separation.
