title = "Gas transport properties of intrinsically microporous polymers",
abstract = "This presentation will compare the gas transport properties two classes of polymers of intrinsic microporosity (PIM) for membrane separations. This study includes long-term gas permeability data of PIM-based materials. We studied the pure-gas permeation properties of PIM for over one year and the polymer's properties are exceptional. The initial oxygen permeability dropped from 1,535 Barrer to 700 Barrer after one year of operation. On the other hand, the initial oxygen/nitrogen selectivity increased from 3.7 to 5.2. These are unmatched permeation properties for air separation, which lie far beyond the typical Robeson permeability/selectivity trade-off. In addition, PIM has very high organic-vapor/permanent-gas selectivity and permeability. For example, PIM-1 has a mixed-gas n-butane/hydrogen selectivity of 30-50 depending on the feed composition.",
