Brominated styrene-butadiene copolymers are useful gas transport films. The gas transport films are made by brominating a starting styrene-butadiene copolymer, and then forming the brominated styrene-butadiene copolymer into a film. The film may contain a blend of the brominated styrene-butadiene copolymer with one or more other polymers. The films have excellent selectivities between certain pairs of gasses, and exhibit high gas transport rates for various gasses such as carbon dioxide and water vapor.
