A series of new fluorine-containing polyimides have been synthesized from the condensation of 2,2-bis[4-(4-aminophenoxy)phenyl]propane, 2,2-bis[4-(4-aminophenoxy)phenyl] -1,1,1,3,3,3 -hexafluoropropane, or 2,2 -bis[4 -(4 -amino -2 -trifluoromethylphenoxy)phenyl]-1,1,1,3,3,3-hexafluoropropane with va
## Abstract A series of new polyimides containing fluorinated alkoxy side chains are prepared from novel fluorinated alkoxy diamines. The dieletric constant at 1 kHz in the fluorinated polyimides decreases from 3.3 to 2.6 as fluorine content increases. The refractive index also changes from 1.58 to
