PURPOSE:To form a gas separation film superior in permeability, separation performance, and physical film property, by mixing a polymer of 2-alkyne having no 1-alkyne unit, with a polymer of 1-alkyne having no 2-alkyne to form a film. CONSTITUTION:A copolymer obtained from 1-alkynes, such as tertiary butyl acetylene, tertiary pentyl acetylene, and neopentylacetylene, with a copolymer obtained from 2-alkynes, such as 2-hexyne, 5-methyl-2-hexyne, 2-heptyne, 2-octyne, 2-nonyne, and 2-decyne, are dissolved in a proper solvent in 9/1-1/9 mixing ratio, and cast into a film. The obtained gas separation film is superior in physical film property to a film made of the copolymer of 1-alkynes and in separation performance to a film made of the copolymer of 2-alkynes. |
