Abstract:  The concentration dependence of the characteristics of light scattering was studied in the systems tetrahydrof uran—dimethylf ormamide and tetrahydrofuran—dimethylformamide—poly(vinyl chloride). The character of the isotherm of the concentration light scattering in the tetrahydrofuran—dimethylformamide—poly(vinyl chloride) system has revea­led the presence of specific interactions in the region of maximum solubility of polyvinyl chloride) in the mixed solvent tetrahydrofuran—dimethylform­amide. Simultaneously it has confirmed the assumption that the composition of the solvate sphere of macromolecules at their maximum solubility is identical with the composition of solvent among macromolecules.
