A series of fluorine-containing copolyimides were synthesized by three different orders of addition of monomers. The fluorine-containing copolyimides were prepared by the reaction of 4,4Ј-diaminodiphenylmethane (DDM) with 2,2Ј-bis(3,4dicarboxyphenyl) hexafluoropropane dianhydride (6FDA), and pyromel
