Annotation	The plots of relative He permeabilities vs. content of inorganic filler exhibited for the mixed matrix membranes of the type polyimide silicalite-1 significant deviations from dependences predicted by the Bruggeman model. The deviations could be explained by membranes stratification to the system of two or three quasi-uniform layers whereas one of the layers of the three layer system contains the continuous network of macropores.
