Abstract
Official abstract text for this publication.
A gas separation membrane including, a separation-active membrane containing: a compound represented by the following Formula (I) having a boiling point or a decomposition temperature of 200° C. or higher; and a cross-linked polymer containing a dissociable group and a repeating unit derived from alkylene glycol: wherein, in Formula (I), R 1 , R 2 and R 3 represent a hydrogen atom or a substituent; W i represents a bivalent linking group; when R 1 , R 2 and R 3 represent a substituent, R 1 and R 2 , R 1 and R 3 or R 2 and R 3 may be combined together to form a ring and wherein, in the compound represented by Formula (I), [total molecular weight of primary amine group+total molecular weight of secondary amine group]/[molecular weight of Formula (I)] is from 0.3 to 0.84.
