Abstract

PURPOSE:To obtain the title gas separation membrane having high gas selectivity and gas permeation rate by linearly polymerizing the epoxy-modified monomer shown by the following formula I, and adding a nitrogen compd. to the unreacted epoxy group of the obtained polymer. CONSTITUTION:The epoxy-modified monomer shown by formula I is linearly polymerized, and formed into a membrane. The nitrogen compd. such as pyridine beta-sulphonate, NH3, C3H5, NH2, and Si(CH3)3NH is added to the unreacted epoxy group of the obtained polymer by a reaction to obtain a gas separation membrane. The O2/N2 selectivity and gas permeation rate of the obtained membrane are high. In addition, the monomer shown by formula I can be copolymerized with the monomers of styrene and CH2=C(CH3)COOH.
