Two series of amorphous fluoro-poly(ether-imide) (6F-PEI) and one series of fluoro-coploy(ether-imide) (6F-CoPEI) polymers based on 2,2bis(3,4-dicarboxyphenyl) hexafluropropane dianhydride (6FDA) and di-ether-containing diamines: 1,2 -bis(4-aminophenoxy)benzene (o-BAPOB) and 4,4 -bis(4-aminophenoxy)
A novel bis(ether anhydride) monomer, 9,9-bis [4-(3,4-dicarboxyphenoxy)phenyl]fluorene dianhydride (4), was synthesized from the nitrodisplacement of 4-nitrophthalonitrile by the bisphenoxide ion of 9,9-bis(4-hydroxyphenyl)fluorene (1), followed by alkaline hydrolysis of the intermediate tetranitril
The polymerization of bisphenol-A diphthalic anhydride with 2,3-bis(perΒ―uoroalkyl methyl)butane-1,4 diamine (NFD) led to a new series of Β―uorinated poly(ether imide)s. In the case of C 4 F 9 perΒ―uoroalkyl chain, polymers and copolymers obtained from a mixture of m-phenylenediamine and NFD were chara
