- Аннотация: Polymer composition has been prepared on the basis of commercial siloxane rubber SKTN-D and tris-(methyldiethoxysiloxy)iron with the reagent ratio 60 : 40 wt %, respectively. Transport parameters of individual hydrocarbons C1–C4 have been shown to be comparable with those for polydimethylsiloxane published previously. Permeability coefficients P of single hydrocarbons C2–C4 increase with an increase in the penetrant feed pressure. It has been demonstrated for n-butane that such increase in P resulted from both a higher diffusion coefficient and solubility coefficient of the penetrant. For mixed gas permeation of C1–C4, an increase in P of methane and a decrease in P of n-butane are observed with increasing the feed pressure. These trends may be explained by the plasticization of the polymer compound and the presence of “rigid” polycyclic structures based on the iron-siloxane component. Similar behavior has been observed for methane and C2+ components with separating quaternary mixture of C1–C4 hydrocarbons. Separation selectivities with respect to methane decreased with increasing feed pressure; however, they become comparable with corresponding results for previously studied substituted polytricyclonones.
