Membrane for selective permeation of oxygen gas

Abstract

Abstract PURPOSE:To obtain the membrane through which oxygen gas can selectively permeate as compared with other gases, esp. nitrogen gas, by forming the selective oxygen gas-permeable membrane from a macromolecular derivative contg. a specified side-chain-substituted group. CONSTITUTION:The selective oxygen gas-permeable membrane is formed from a macromolecular derivative contg. a side chain-substituted group defined by the formulaI(where, Y=F, Cl, etc., m=0 or 1 and n=1-10) such as a cellulose or alcohol derivative. This permeable membrane is useful, since it makes oxygen gas permeate through it with a large ratio of oxygen permeation as compared with other gases, esp. nitrogen gas.
