摘　　要：采用2,2-双(3-氨基-4-羟基苯基)六氟丙烷和4-硝基邻苯二甲腈为原料,通过亲核取代反应制备了一种含氟元素的双氨基邻苯二甲腈树脂(FPN-p)。通过傅里叶红外光谱(FT-IR)和核磁氢谱(1H-NMR)对其化学结构进行表征,通过差示扫描量热法(DSC)和FT-IR考察了树脂的固化行为,并研究了树脂的热稳定性、热机械性能以及耐湿热性能。研究结果表明:FPN-p树脂在不加促进剂的情况下可实现自催化聚合,产物结构以三嗪环和酞菁环为主;树脂的玻璃化转变温度和质量分数5%热分解温度均超过400℃,耐温等级较高;树脂的耐湿热性能良好,高温水煮168 h后吸水率小于1%。该树脂有望用于耐高温涂层、树脂基复合材料以及高性能胶粘剂等领域。A kind of fluorine-containing diaminophthalonitrile resin(FPN-p)was prepared by nucleophilic substitution reaction using 2,2-bis(3-amino-4-hydroxyphenyl)hexafluoropropane and 4-nitrophthalonitrile as raw materials.Its chemical structure was characterized by Fourier infrared spectroscopy(FT-IR)and nuclear magnetic resonance spectroscopy(1H-NMR),the curing behavior of the resin was investigated by differential scanning calorimetry(DSC)and FT-IR,and the thermal stability,thermal mechanical properties and moisture heat resistance of the resin were also studied.The research results showed that FPN-p resin could realize autocatalytic polymerization without accelerator,and the product structure was mainly composed of triazine ring and phthalocyanine ring.The glass transition temperature and thermal decomposition temperature with 5%mass fraction of the resin both exceeded 400℃,indicating a high temperature resistance level.The resin had good moisture heat resistance,the water absorption rate was less than 1%after 168 hours of high-temperature water boiling.The resin was expected to be used in fields such as high-temperature resistance coatings,resin based composites,and high performance adhesive.
