Abstract.A series of a novel class of linear aromatic ether polymers (AEP) containing perfluorocyclobutyl and triazole unites were synthesized by click chemistry and their structures and properties that were characterized by FT-IR, 1H NMR, GPC, TGA, DSC and WAXD. The results showed that these polymers exhibited relatively small molecular weight distributions (about 1.1), mostly were amorphous, and had good solubility in most dipole solvents and thermal stability. These polymers were reported to have potential value in material science. The reaction mechanism was well elucidated of the click chemistry indicated that it was efficient for polymerization.
