以双螺环取代三聚磷腈基双苯甲酰氯和4-氨基（N-苯基）苯并噁嗪单体为原料合成了一种含双螺环取代三聚磷腈结构单元的苯并噁嗪树脂单体（HCP-5）；采用傅立叶变换红外光谱仪（FT-IR）和核磁共振谱仪（1 H NMR ，13C NMR ，31P NMR）表征了苯并噁嗪树脂单体的结构，基于 FT-IR和示差扫描量热法研究了其固化行为，并利用热重分析和示差热重分析研究了HCP-5树脂单体、均聚物及其与双酚A型苯并噁嗪树脂（Bz）共聚物的热稳定性。结果表明，HCP-5均聚物具有很好的热稳定性和成炭性，其在317℃下的热失重为5％，在800℃下的残炭率为50％，可用于普通苯并噁嗪树脂改性。此外，H C P-5/Bz （1∶1；质量分数）共聚物在332℃下的热失重为5％，在800℃下的残炭率为48％。
