Abstract: An m-phenylenediamine compound is represented by the following General Formula (I), (II), or (III). R1 represents a hydrogen atom, an alkyl group, a cycloalkyl group, or an aryl group. R2, R3, and R4 each represent an alkyl group. R5 and R6 each represent an alkyl group. X represents a chlorine atom or a bromine atom. A method for producing a polymer compound includes obtaining a polymer compound by using the m-phenylenediamine compound represented by General Formula (I) as a raw material.

Abstract: A gas separation membrane includes a gas separation layer containing a polyimide compound, and the polyimide compound has a repeating unit represented by Formula (I). The gas separation module, the gas separation device, and the gas separation method are obtained by using the gas separation membrane, Ra represents a specific tetravalent group, Rb represents a trivalent group having a specific ring, Xa represents a specific substituent, and Xb represents a hydrogen atom or a substituent. A polyimide compound represented by Formula (I-b) or (I-c), Ra represents a specific tetravalent group, Rc represents a specific divalent group, Aa, Ab, Ac, and Xb represent a hydrogen atom or a substituent, and Xc and Xd represent a specific substituent.
