Abstract: The gas permeation properties of a series of cardo polyaryletherketone materials are reported.In this series,hydrogen atoms of benzene rings on the backbone are systematically replaced with different alkyl substituents.The effects of temperature and structure variation on gas permeability and selectivity are discussed in detail.The experimental results revealed that the polyetherketone obtained by the introduction of dimethyl and diisopropyl substituents to phenolphthalein unit is 3~6 times more permeable than the unmodified one for the gases studied.

Key words: Polyaryletherketone, Membrane, Gas separation
