摘　　要：以含磷中间体(BPPP),烯丙基胺,甲醛溶液为原料合成了一种含磷烯丙基胺型苯并噁嗪,并采用核磁共振氢谱(1H-NMR)、傅里叶红外光谱(FTIR)、差示量热扫描仪(DSC)和热失重分析仪(TGA)对其化学结构、固化行为及热稳定性进行了表征。结果表明,含磷烯丙基胺型苯并噁嗪的固化温度为216℃。固化产物的5%和10%热失重温度分别为269和315℃。800℃时的残炭高达51%,表明聚苯并噁嗪具有良好的热稳定性。An allyamine-based benzoxazine monomer containing phosphorus was synthesized by using BPPP, formaldehyde and allylamine as starting materials. Additionally, Fourier transform infrared spectroscopy （FTIR）, proton nuclear magnetic resonance spectroscopy （^1H-NMR）, differential scanning calorimetry （DSC） and thermogravimetric analysis （TGA） were used to characterize chemical structure, curing behavior and thermal stability. The results show that the curing temperature of benzoxazine is 216 ℃. The 5% and 10% weight loss temperatures of polybenzoxazine are 269 ℃ and 315 ℃ respectively with the char yield of up to 51% at 800℃, indicating that the polybenzoxazine has good thermal stability.
