The polymer material may be a modified poly(dimethylsilane) having a backbone including dimethylsiloxyl monomers, substituted methylsiloxyl monomers, and internal-network monomers. The substituted methylsiloxyl monomers may include phenyl- methylsiloxyl monomers or C-Cio alkylmethylsiloxyl monomers such as octylmethylsiloxyl monomers. The polymer material may 5 include silicon-alkyl linkages such as Si-(CH2) n -Si, where n > 2 that may create a structure that imparts desirable permeability and selectivity characteristics to the composite membrane. The polymer material may be cast onto a porous support material. The composite membranes may be incorporated into systems or methods for removing heavy hydrocarbons from natural gas.
