摘　　要：以双环戊二烯、乙二醇和六氯环三磷腈为原料合成一种新型环三磷腈基多官能脂环族环氧化合物(PCNEP)。采用傅里叶变换红外光谱、核磁共振、质谱分析和测定环氧值等方法对 PCNEP 及其中间体的化学结构进行了表征。合成的脂环族环氧树脂用甲基四氢邻苯二甲酸酐固化,并通过热重分析将 PCNEP 固化物的热性能与商品化脂环族环氧树脂 ERL-4221进行了比较。结果表明:PCNEP 固化物的起始热分解温度低于 ERL-4221固化物,但在500℃和700℃的高温下,PCNEP 固化物的残炭量分别为28.87%,24.73%。A novel polyfunctional cycloaliphatic epoxide （PCNEP） in liquid state was synthesized from dicyclopentadiene, ethylene glycol and cyclophosphonitrilic chloride trimer. The chemical structure of the resultant epoxy resin and its precursor were characterized by fourier transform infrared spectroscopy （FTIR）, epoxy value, hydrogen-1 nuclear magnetic resonance spectroscopy（^1H-NMR） and mass spectrography （MS）. The thermal properties of PCNEP cured by methyltetraydrophthalic anhydride were evaluated with thermogravimetric analysis. Compared with ERL- 4221, a commercial cycloaliphatic epoxy resin, PCNEP exhibited lower thermal degradation temperature but much higher char yield, reaching 28.87% and 24.73% at 500 ℃ and 700 ℃, respectively.
