摘要: Abstract A novel fluorinated aromatic diamine, bis[4-(4′-aminophenoxy)phenyl]-3,5-bis(trifluoromethyl)phenyl phosphine oxide, was synthesized. series of new polyimides containing oxide prepared from the diamine with various commercially available dianhydrides. All show high glass transition temperatures, excellent thermal stability, and good solubility in common organic solvents.
