GAS SEPARATION MEMBRANE, METHOD FOR PRODUCING THE SAME, AND GAS SEPARATION MEMBRANE MODULE

摘要

PROBLEM TO BE SOLVED: To provide a gas separation membrane which has high separation selectivity and permeability at high pressures while exhibiting high organic solvent resistance.SOLUTION: A gas separation membrane has a separation layer that contains a polymer having a crosslinked structure. The polymer having a crosslinked structure contains a structure that is crosslinked through a linking group derived from a ketenimine crosslinking agent having at least two groups represented by general formula (1), where each of Rand Rindependently represents a substituent and the symbol * represents a binding site.
