Abstract

The gas permeation behaviour of a number of polyimide copolymers, including a series of copolyimides of identical structure with different molecular weights, have been investigated. Permeabilities and selectivities were found to vary over a broad molecular weight range at high molecular weights. Differences in permeability with molecular weight can be comparable to differences due to marked changes in chemical structure.
