The polymer film contains a polymer material that selectively permeates acid gases over methane in a gas stream such as natural gas. The polymer material can be a polymer membrane containing a fluorinated polytriazole polymer. The fluorinated polytriazole polymer may further comprise substituted phenyl or substituted benzenaminyl. The substituted phenyl or substituted benzenaminyl can be substituted with hydrogen, bromo, fluoro, chloro, iodo, hydroxy, methyl, trifluoromethyl, dimethylamino, tert-butyl, or a difluoromethoxy group. The polymer material can have a degree of polymerization of 100-175. Polymer membranes can be incorporated into systems or methods for removing separable gases such as acid gases from gas streams such as natural gas. |
