Notes:
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.
