Abstract:
It is demonstrated that the multifractal model of processes of gas transport and the associated treatment of the part of amorphous phase accessible for diffusion enable one to make a correct quantitative description of the diffusion coefficient of various gases in polyethylene and of its temperature dependence. The physical meaning is revealed of the exponent $m$ in the equation for determining the diffusion coefficient of gases in amorphous-crystalline polymers. The boundary value is obtained of the diameter of molecule of penetrant gas, which defines the mono-to-multi-fractal transition of the mechanism of gas transport.
