A comparative analysis of the diffusion process of the macromolecular chain in the polymer matrix was performed within the frameworks of the De Gennes, Edwards, and Doi approaches. The parameters of an elementary diffusion jump of the reptation loop were determined from the original experimental data on diffusion, self-diffusion, and the activation energy of diffusion of vinyl chloride and vinyl acetate...
Electron-probe microanalysis was used to study diffusion in systems composed of poly(vinyl chloride) and statistical copolymers of vinyl chloride and vinyl acetate. The coefficients of mutual diffusion and the activation energies of diffusion were determined. The ability to calculate the self-diffusion coefficients of the homopolymer and the copolymers was shown.
