Preparation and properties of soluble polyamideimides containing oligo(tetrafluoroethene) segments and application in gas separation

A series of PMDA‐, BTDA‐ and 6F‐polyamideimides containing well‐defined oligo(tetrafluoroethene) segments were derived from N,N′‐bis(aminophenyl)perfluoroalkane‐α, ω‐dicarboxamides with n =1,2,3 tetrafluoroethene units. The influence of the fluorine content, microstructures and the oligo(tetrafluoro...

Zusammenfassung:A series of PMDA‐, BTDA‐ and 6F‐polyamideimides containing well‐defined oligo(tetrafluoroethene) segments were derived from N,N′‐bis(aminophenyl)perfluoroalkane‐α, ω‐dicarboxamides with n =1,2,3 tetrafluoroethene units. The influence of the fluorine content, microstructures and the oligo(tetrafluoroethene) segment lengths on phase transition temperatures, thermal degradation, contact angles, pure gas permeabilities and permselectivities was studied.
