Abstract: A study has been conducted to determine if a polymeric membrane consisting of a homogenous blend of the polyimides Matrmid® 5218 and P84 can be created, and if the H2/N2 selectivity of this membrane would compare to that of pure Matrimid® 5218. This research shows that by using NMP as a common solvent, a homogenous blend of both polyimides can be achieved. The experiment outlined in this report achieved a maximum H2/N2 selectivity of 50.4 using a 50/50wt% blended membrane, and a maximum H2/N2 selectivity of 51.6 for a pure Matrimid® membrane. Further investigation was conducted into the effects of annealing and cross-linking these membranes, though the results are inconclusive.
