文摘

A new kind of aromatic diamine monomer containing pyridine unit, 2,6-bis[4-(4-aminophenoxy)phenoxy]pyridine (BAPP), was synthesized in three steps, using hydroquinone as starting material. A novel pyridine-containing polyimide was prepared from the resulting diamine BAPP with 4,4′-oxydiphthalic anhydride (ODPA) via a conventional two-step thermal imidization method. The resulting polyimide exhibits excellent solubility, film-forming capability and high thermal resistance.
