高性能高分子材料在高温下仍保持优异的综合性能,是航空航天、电子电气、高速轨道交通等重要高技术领域不可或缺的材料。在不牺牲耐热性能的前提下改善高性能聚合物的加工性能一直是国内外研究的热点。含二氮杂萘酮结构高性能聚合物是高性能高分子材料的新成员。本文主要综述了含二氮杂萘酮结构的聚芳醚(包括聚芳醚砜酮系列、聚芳醚腈砜酮系列、聚芳醚砜酮酮系列和聚三芳基三嗪环系列)、聚芳酰胺、聚芳酯的合成与性能的研究进展。因二氮杂萘酮联苯结构具有扭曲、非平面和稠环结构特点,使上述聚合物既耐高温又可溶解,加工方式多样,即可热成型加工(模压、挤出、注射等),又可溶液方式加工,应用领域广泛。

High-performance polymers with excellent comprehensive properties have been becoming crucial materials for their applications in aerospace, automobile, electronics, and other high technology fields. Modifying their processibility without sacrifice of their outstanding thermal stability is receiving considerable attention. Polymers containing phthalazinone moieties are a series of novel high performance thermoplastics. In this paper, the synthesis of poly（phthalazinone ether）s, involving poly （phthalazinone ether sulfone ketone）s, poly （phthalazinone ether nitrile sulfone ketone）s, poly （phthalazinone ether sulfone ketone ketone）s and poly（phthalazinone ether triphenyl 1,3,5-triazine）s , and their structure-property were elaborately reviewed. They have outstanding thermal stability and good solubility in some aprotic polar organic solvents because of introducing twist and non-eoplanar phthalazinone moiety into polymer main chain. Thus they can be processed by melting, such as injection, extrusion and molding, and in solution in the result of expanding their application, such as in coating and membrane.
