ABSTRACT:
The inventive shaped body for gas separation is prepared on the base of a film shaped of a poly(silyl acetylene) such as poly(1-methyl-2-trimethylsilyl acetylene) by subjecting the base film to a treatment of exposure to an atmosphere of low temperature plasma of an inorganic gas, e.g. nitrogen, hydrogen, argon, etc. Contrary to expectation, the base film is stable against the plasma treatment without decrease in the mechanical strengths and imparted with high performance for gas separation, especially, for the enrichment of oxygen in air with a separation factor between oxygen and nitrogen of 2.5 to 3.5.
