Theoretical and experimental studies have been carried out, which makes it possible to evaluate the mechanisms of the transport of organic nonpolar solvents in organosilicon polymers. It is shown that for nonpolar solvents the transport mechanism is diffusion of the second type, which also depends on the swelling kinetics, and the anomalous diffusion, sorption and transport of molecules at which the microvoid is present in the polymer matrix. The article presents graphs of the dependence of the mass of substances that are absorbed and released by the polymer for several of the most common solvents.
