Abstract
PURPOSE:To obtain a gas-permeable membrane excellent in permeability, separating ability and stability, by forming on a porous support a polymeric thin membrane of an organopolysiloxane having no film-forming ability, subsequently forming on the membrane a thin membrane of an acetylene polymer in which the main chain has a double bond, and then subjecting the resulting composite membrane to ultraviolet radiation. CONSTITUTION:A thin membrane of either an organopolysiloxane or an organopolysiloxane copolymer which have no film-forming ability, such as methylhydrogen polysiloxane, is allowed to adhere to the surface of a porous support. Then, a solution of poly-1-(trimethylsilyl)propyne in n-hexane etc. is dropped on the surface of water to from a water surface-cast membrane. This cast membrane is bonded with the surface of the porous support to which the organopolysiloxane has adhered, thereby to form a composite membrane. The surface of this composite membrane is irradiated with ultraviolet rays to prepare a composite membrane having selective permeability to gases.
