The Solubility of Hydrocarbon Gases in Glassy Polymers : Fractal Modeling

الملخص EN

This work describes the fractal modeling of the solubility of n-alkanes, n-alkenes, methylacetylene, allene, ethylacetylene, and butadiene hydrocarbon gases in glassy poly(vinyltrimethylsilane) (PVTMS).

The proposed equation represents satisfactorily the solubility coefficients of the hydrocarbon gases in glassy PVTMS as a function of the fractal dimension of the polymer and the effective diameter of a gas penetrant molecule.

It is found that the calculated solubility coefficients have a good correlation with the experimental data.

The proposed model can predict the solubility of hydrocarbon gases in glassy polymers.
