초록
Aromatic pelybenzoxazoles(PBOs) display excellent thermal stability plus good solvent and chemical resistance. Wholly aromatic PBOs, in fact, are soluble only in strong acids(e.g., sulfuric, rmethanesulfonic, triflic, and polyphosphoric acids). However, fully heterocyclized polymers have shown some drawbacks in solubility and processing. This problem of processing is currently being exploited to obtain unusual combinations of physical properties in fibers and films. (omitted)
