摘　　要：以4种含杂萘联苯结构的类双酚单体分别与2，6-二氯苯腈、4，4-二氟酮进行亲核缩聚反应，制备了一系列新型含杂萘联苯结构的聚芳醚腈酮树脂。研究了不同类双酚单体结构对聚合物性能的影响。所制备聚合物均具有较高的分子量，特性粘度在0．50dL／g以上，可溶解于N-甲基吡咯烷酮（NMP），N，N-二甲基乙酰胺（DMAc），氯仿等极性非质子型有机溶剂中。聚合物的结构以FT-IR进行表征；利用差示扫描量热仪（DSC）和热重分析仪（TGA）研究了聚合物的耐热性能，结果表明，该类聚芳醚腈酮树脂具有优异的耐热性能，玻璃化转变温度（Tg）在255～277℃之间，10％热失重温度（Td）在498℃以上。由该系列聚芳醚腈酮材料制成的绝缘漆具有良好的电绝缘性能，较高的机械强度，良好的柔韧性和附着力。Soluble,thermally stable aromatic poly（phthalazinone ether nitrile ketone）s （PPENK） have been synthesized by the nucleophilic displacement reaction of four kinds of phthalazinone-containing bisphenol-like monomers with 2,6-dihalobenzonitrile and 4,4＇-diflurodiphenylketone, respectively. The structures of polymers were characterized by FT-IR spectra. The inherent viscosities of these PPENKs were in the range of 0.50 to 1.17dL/ g. All the PPENKs were amorphous,and showed good solubility in a variety of polar non-protonic solvents such as chloroform, N-methyl-2-pyrrolidone （NMP）, and N, N-dimethylacetamide （DMAc） at room temperature, which made it possible to easily east them into flexible and transparent films. They had useful levels of thermal stability associated with glass transition temperature in the range of 255 to 277℃, 10% weight-loss temperature in excess of 498℃ in nitrogen. These soluble PPENKs were applied to prepare insulating coatings. The insulating coatings of PPENKs exhibited high mechanical strength,good flexibility and adhesion,and favorable electroinsulating property.
