摘要:

介紹了含二氮雜萘酮聯苯結構聚芳醚砜酮、聚芳醚腈砜酮以及同時還含芳基均三嗪環結構聚芳醚三大系列新型高性能工程塑料的合成與性能及其在高性能樹脂基復合材料、絕緣漆、漆包線、功能涂料以及耐高溫功能膜等領域的研究進展。從分子結構設計出發，研制成功具有扭曲、非平面結構特點的含二氮雜萘酮聯苯結構新型單體，進而與雙鹵單體經親核取代逐步聚合反應合成了多系列含二氮雜萘酮聯苯結構新型聚芳醚類高性能工程塑料，既耐高溫又可溶解，解決了傳統高性能工程塑料不能兼具耐高溫可溶解的技術難題。其玻璃化轉變溫度達250～375 ℃，5%熱失重起始溫度均高于500 ℃；可溶解于N�布谆�吡咯烷酮、N, N�捕�甲基乙酰胺以及氯仿等幾種有機溶劑；綜合性能優異，尤其是在高溫下依然保持優異的綜合性能；可多種方式加工，不僅可采用模壓、擠出、注射等熱成型加工，還可采用溶液方式加工應用；廣泛應用于航空航天、核能、電子電氣等高技術領域和國民經濟眾多行業部門。

Abstract:

Herein, we reported the synthesis and properties of poly(phthalazinone ether sulfone ketone), poly(phthalazi ether nitrile sulfone ketone) and poly(phthalazinone ether phenyl s triazine), and their typical applications in polymer matrix composites, insulation varnish, insulation enameled wire, functional coating and functional membrane. Starting from the molecular structure design, a novel monomer, 4 (4 hydroxyl phenyl) 2,3 phthalazin 1 one (DHPZ), having unsymmetrical nature, twisted and noncoplanar conformation, has been designed and synthesized. This monomer behaves like bisphenol and can react with activated dihalo compounds to produce high molecular weight phthalazinone�瞔ontaining poly(aryl ether)s through classical nucleophilic aromatic substitution reactions.
