The peculiarity of interdiffusion and phase equilibrium has been studied for poly-m-phenyleneisophthalamide and poly-p-amidobenzimidazole systems during formation of a transitional layer in conditions of organoplastics. The investigation of this process has been based on the method of electron-probe X-ray spectral microanalysis. The effect of temperature, pressure and time of thermal treatment on dimensions of diffusional zones and kinetics of their formation was shown. The parameters of solubility and mutual diffusion of components were determined and phase diagrams were obtained.
