| titleOfInvention | Fluorinated condensation copolyimides |
| abstract | A fluorinated condensation copolyimide has repeating polymer units that include: <IMAGE> +TR <IMAGE> in which X and Y are diamines. The copolyimide can be made by reacting a 3F-monomer and a 6F-monomer with an aromatic or aliphatic diamine. The 3F-monomer includes 4,4'-(2,2,2-trifluoro-1-phenylethylidene) diphthalic anhydride, a dialkylester of 4,4'-(2,2,2-trifluoro-1-phenylethylidene) diphthalic anhydride, 4,4'-(2,2,2-trifluoro-1-phenylethylidene) diphthalic acid, or mixtures thereof. The 6F-monomer includes 4,4'-[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene] diphthalic anhydride, a dialkylester of 4,4'-[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene] diphthalic anhydride, 4,4'-[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene] diphthalic acid, or mixtures thereof. |
