Method for manufacturing polyimide asymmetric membrane, and polyimide asymmetric membrane |
| abstract |
A process of producing an asymmetric membrane of multicomponent polyimide. The process includes the steps of (1) preparing a multicomponent polyimide blend solution by mixing a polyimide component A having a number-averaged polymerization index N A and a polyimide component B having a number-averaged polymerization index N B , wherein N A and N B satisfies equation 1: n n2.35×N A −2.09 <N B <450×N A −1.12 1 n(2) subjecting the multicomponent polyimide blend solution to further polymerization and imidation reaction, and (3) causing a phase inversion in the resulting multicomponent polyimide blend solution to form an asymmetric membrane. The polyimide component A is raw materials of polyimide A containing a fluorine atom in the chemical structure thereof and/or a polymerization and imidation reaction product of the raw materials. The polyimide component B is raw materials of polyimide B and/or a polymerization and imidation reaction product of the raw materials. |
