Abstract
PURPOSE: To simply manufacture an extremely thin membrane having excellent selective permeability, by a method in which a polymer composed mainly of poly(4- methylpentene-1) is dissolved in a solvent to which is added an alcohol, etc., and then the solution is spread over the surface of water to form a film.
CONSTITUTION: A polymer composed mainly of poly(4-methylpentene-1) is dissolved in a solvent, e.g., cyclohexane, etc., to which is added a compound, e.g., an alcohol, or a phenol, and then the solution is supplied and spread over the surface of water to form an extremely thin membrane. Thus, the extremely thin membrane can be easily manufactured and can be used as a separation membrane for gas, particularly oxygen, because of its excellent selective permeability.
