摘要：

A transient increase of the separation factor alpha(C2H4/C2H6) was observed upon a rapid increase of the pressure of an ethylene-ethane mixture over homogeneous membranes made of polyphenyleneoxides. Separation factors as high as 20-50 were achieved with the relaxation time being close to 100-200 minutes for the 60-70 micrometer thick films. The reasons for the increased permselectivity of polyphenyleneoxides towards olefins are discussed.
