Abstract:  The solutions of two fractions of poly(vinyl chloride) (PVC) in N,N-dimethylformamide (DMFA), cyclohexanone (CYH), and dioxan were thermodynamically characterized. The second virial coefficients and the values of interaction parameters χ were determined osmometrically for each solvent at three temperatures. Moreover, the rate of free diffusion in solutions of PVC in the above-mentioned solvents was studied as a function of composition and temperature. The thermodynamic and hydrodynamic factors of the diffusion coefficient were determined. The dependence of both factors on composition and temperature is described.
