HIGHLY PERMEABLE AND HIGHLY SELECTIVE POLYIMIDE COPOLYMER AND METHOD FOR SYNTHESIZING SAME |
| 摘要 |
Provided are a high-molecular weight polyimide used for a gas separation membrane and a method for synthesizing the same. The polyimide contains 4,4′-(hexafluoroisopropylidene)diphthalic anhydride, 2,3,5,6-tetramethyl-1,4-phenylenediamine, and 1,3-bis[2-(4-aminophenyl)-2-propyl]-benzene. According to the present invention, a gas separation membrane having high oxygen permeability and high oxygen selectivity may be provided. |
