| titleOfInvention | Gas separation membrane |
| abstract | The diamine and carboxylic acid dianhydride for polymerizing a polyimide containing a hexafluoroisopropylidene group are chemically constrained when used as a polyimide membrane, and therefore, when used as a gas separation membrane, There is a problem that it is difficult to design the structure. A gas separation membrane which is easy to dissolve in an organic solvent and is excellent in moldability and easy to use as a gas separation membrane and which is excellent in gas separation performance is obtained. In general formula (1): (61) (In the formula (1), R 1 is a divalent organic group and R 2 is a tetravalent organic group, and R 1 is a 2-hydroxy-1,1,1,3,3,3-hexafluoroisopropyl group :. (- C (CF 3 ) 2 OH) and including) a gas separation membrane comprising a polyimide including a repeating unit represented by the. |
