A method for the preparation of poly(benzoxazole)s, poly(benzimidazole)s, and poly(benzthiazole)s. In the presence of solvent and catalyst, reacting carbon monoxide, an aromatic halide reactant having the general formula X¹-Ar¹-Z¹ and an aromatic amine reactant having the general formula Z²-Ar²-M¹, wherein X¹ and Z¹ are non-ortho, Z² and M¹ are non-ortho, one of Z¹ and Z² is X² and the other one is M², -Ar¹- and -Ar²- are each independently selected from the group consisting of aromatic and hetero-aromatic moieties having a total of ring carbons and heteroatoms of from 6 to 20, X¹ and X² are each independently selected from the group consisting of -I and -Br, and M¹ and M² are each independently selected from moieties having an -NH₂ radical and, ortho to the -NH₂ radical, a radical selected from the group consisting of -NH₂, -OH, and -SH.
一种制备聚(苯并恶唑)、聚(苯并咪唑)和聚(苯并噻唑)的方法。在溶剂和催化剂存在下,使一氧化碳、通式为 X¹-Ar¹-Z¹ 的芳族卤化物反应物和通式为 Z²-Ar²-M¹ 的芳族胺反应物反应,其中 X¹ 和 Z¹ 为非正交,Z² 和 M¹ 为非正交,Z¹ 和 Z² 中的一个为 X²,另一个为 M²、-Ar¹-和-Ar²-各自独立地选自由环碳原子和杂原子总数为 6 至 20 的芳香族和杂芳香族分子组成的组,X¹和 X² 各自独立地选自由-I 和-Br 组成的组,M¹和 M² 各自独立地选自由具有-NH₂基的分子以及与-NH₂基正交的选自由-NH₂、-OH 和-SH 组成的组的基。
