Abstract:  A convenient approximation of the concentration profile in the system polymer (PVAc)—solvent (ethyl acetate, acetone, methanol) ascertained by the method of wedge interferometer has been found. The values of mutual diffusion coefficients have been calculated for particular compositions of the system by the Matano—Boltzmann method.
