Abstract
Optical interferometers for study of mutual diffusion in polymer-solvent systems are considered. The methodology of experiment for the pair of cellulose acetate (as a fiber) - nitromethane (an aprotic and dipolar solvent) is discussed. The kinetics of spatial distribution ofthe medium's refraction index in the process of mass transfer is considered. The kinetics of movement of equal-concentration planes and that of concentration profile changes are determined.
