Turbidimetric results obtained with the ternary systems N,N-dimethylformamide/cyclohexane/polystyrene, N,N-dimethylformamide/cyclohexane/polybutadiene, methanol/cyclohexane/polystyrene, methanol/cyclohexane/poly(ethylene glycol) are reported. These results show that a very small quantity of polymer changes drastically the demixing curve of the two partially mixed liquids. The displacement of the heterogeneous region starts from the domain of the critical point of the two liquids and becomes more significant in the domain of compositions of the two liquids rich in the poor solvent of the polymer. A qualitative explanation of this phenomenon is attempted based on the theory of the isorange lines of two partially miscible liquids.
