摘要：

Interdiffusion in polystyrene-poly(vinyl methyl ether) systems is studied by optical-interferometry method in wide temperature and concentration ranges. For these systems, temperature-concentration dependences are constructed, activation energies are calculated, and dependences of the diffusion coefficient on the molecular mass of polystyrene are examined. The results are compared with the phase diagrams of the systems, and it is shown that the diffusion coefficient decreases as the binodal curve is approached, thereby leading to corresponding changes in the Arrhenius coordinates.
