POLYMER AND METHOD FOR PRODUCING THE SAME, GAS SEPARATION MEMBRANE, GAS SEPARATION MODULE, AND GAS SEPARATION APPARATUS USING THE POLYMER, AND m-PHENYLENEDIAMINE COMPOUND

摘要

Provided are a polymer having a constituent component represented by formula (I) below, a method for producing the polymer, a diamine compound suitable as a raw material for the polymer, a gas separation membrane haying a gas separation layer including the polymer, and a gas separation module and a gas separation apparatus that have the gas separation membrane.; ;In the formula (I), RA, RB, and RC represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or a halogen atom. Herein, at least one of RA, RB, or RC represents an alkyl group having 1 to 4 carbon atoms or a halogen atom. The alkyl group having 1 to 4 carbon atoms is not trifluoromethyl and ** represents linking sites.
