摘　　要：采用六氟双酚A(BPF)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双酚AF型邻苯二甲腈树脂(AFPN)。通过傅里叶红外光谱(FT-IR)、核磁氢谱(^(1)H-NMR)、时间飞行质谱(TOF-MS)对其化学结构进行表征。考察了不同固化工艺对AFPN热稳定性、热机械性能和粘接性能的影响。研究结果表明:AFPN的熔点为230℃,1,3-双(3-氨基苯氧基)苯(TPE-M)可以加速其聚合过程;当固化温度为375℃时,AFPN聚合物质量分数为5%时的热分解温度(T_(5%))为501℃,T_(10%)为522℃,玻璃化转变温度(T_(g))为327℃;AFPN树脂具有较好的阻燃性能和高温粘接性能以及潜在的应用前景。A kind of bisphenol AF-type phthalonitrile resin(AFPN)was prepared through nucleophilic substitution reaction by using hexafluorobisphenol A(BPF)and 4-nitrophthalonitrile as raw materials.Its chemical structure was characterized by Fourier transform infrared spectroscopy(FT-IR),hydrogen nuclear magnetic resonance spectroscopy(^(1)H-NMR),and time-of-flight mass spectrometry(TOF-MS).The effects of different curing processes on the thermal stability,thermomechanical properties and bonding properties of AFPN were investigated.The research results showed that the melting point of AFPN was 230℃,and 1,3-bis(3-aminophenoxy)benzene(TPE-M)could accelerate its polymerization process.When the curing temperature was375℃,the thermal decomposition temperature(T_(5%))of AFPN polymer with 5%mass fraction was 501℃,T_(10%)was522℃,and the glass transition temperature(T_(g))was 327℃.AFPN resin had good flame retardancy,high temperature adhesion and potential application prospects.
