It is shown that the diffusivity value of various gases in polyvinyltrimethylsilane is controlled by two factors: molecular mobility level, characterized by fractal dimension of chain part between entanglements, and the size of gas‐penetrant molecule. Very strong power dependence of diffusivity on both these factors, explaining very large variation of diffusivity for limited interval of mentioned dimension, is obtained. © 2006 Wiley Periodicals, Inc.
