摘　　要：以1,2-二(4-羟基苯基)碳癸硼烷(CBR-328)为原料,合成了1,2-二(4-炔丙氧基苯基)碳癸硼烷(CBR-404),红外光谱和核磁共振(1H-NMR,13C-NMR,11B-NMR)表征其结构。在热作用下,CBR-404发生自身固化,利用红外光谱和差示扫描量热分析研究了固化动力学。结果表明,该树脂体系表观活化能为120.17 k J/mol,固化反应级数n=0.93;固化起始反应温度Tonset=228.76℃,峰值固化温度Tcure=267.90℃,后处理温度Ttreat=292.46℃等固化工艺参数;固化后树脂具有良好的热氧稳定性,氩气和空气氛围中,5%失重温度分别是442.8℃和583.2℃,900℃的残留率分别为86.6%和91.6%。1,2-Bis( 4-propargyl ether phenyl) carboranes( CBR-404),characterized by1H-NMR,13C-NMR,11B-NMR and FT-IR,was synthesized by Williamson reaction using 1,2-bis( 4-hydroxyphenyl) carborane( CBR-328).And the curing kinetics of CBR-404 was measured by DSC and FT-IR spectra. The apparent activation energy of curing reaction of the CBR-404,cured by heat,is 120. 17 k J/mol,and the level of curing reaction is 0. 93. The results indicate that the onset cure temperature of CBR-404 is about 226 ℃,the cure temperature is about 260 ℃,and the treat temperature is 285 ℃. The evaluation of the thermal properties demonstrates that the 5% mass loss temperature of the resin is 442. 8 ℃ with the char yield of 86. 6% at 900 ℃ in argon atmosphere. Moreover,the 5% mass loss temperature of the resin is 583. 2 ℃ with the char yield of 91. 6% at 900 ℃ in air atmosphere.
