摘　　要：文中简要概述了聚苯并口恶唑-酰亚胺的性能和应用,并对聚苯并口恶唑-酰亚胺的合成作了较详细的综述,特别阐述了在多聚磷酸中"一锅法"合成聚苯并口恶唑-酰亚胺合成的新方向,以及展望了聚苯并口恶唑-酰亚胺合成研究的前景。The new research advances in synthesis of poly（imide-benzoxazole） （PlBOs） in aprotic solvents and polyphosphoric acid （PPA） were reviewed. Traditionally, PIBOs have been synthesized via the cyclization of precursor polymers from diamine and dianhydride by a two-stage process in aprotic solvents. As result, mechanical properties of PIBOs films made by two-stage process are poor due to the presence of the holes in the process of releasing H2O molecules. In this report, it was especially elaborated that PIBOs were synthesized in PPA through ＂one pot＂ method. PIBO fiber with high strength was spun from PIBO/PPA dope by dry-wet spun method.
