摘要：

An attempt was made to prepare dry asymmetric membranes of aromatic polyimide material for the separation of air-organic vapor mixtures. Membranes with the permeability of organic vapor two orders of magnitude higher than that of air could be obtained. The membrane performance depends strongly on the conditions of membrane preparation. It was found that the permeability of organic vapors exhibits a strong correlation with their cohesive energy data.
