摘　　要：以六氯环三聚磷腈,1,1′-二羟基联苯,对羟基苯甲酸乙酯和含活泼官能团的苯并口恶嗪单体为原料合成了含双螺环取代三聚磷腈结构的苯并口恶嗪单体(HCP)。采用FT-IR,1 H-NMR,13 C-NMR,和31P-NMR进行了表征,并研究了其固化行为以及HCP均聚物和HCP与双酚A苯并口恶嗪树脂(Bz)共聚物的热性能。结果表明,HCP均聚物在氮气氛下的起始热分解温度为333℃,800℃时残炭42%。HCP/Bz共聚物的起始热分解温度为367℃,800℃残炭率达52%,具有比HCP和Bz均聚物更好的热稳定性和成炭性能。A novel benzoxazine based bis-spiro-substituted cyclotriphosphazene（HCP） were synthesized from hexa- chlorocyclotriphosphazene, 2,2 （-biphenol, 4-hydroxybenzoic acid ethyl ester and benzoxazine with active group. The struc- ture of target compounds was confirmed by FT-IR, 1H NMR, 13 C NMR and 31 p NMR. The curing behavior of HCP, ther- mal stability of its homopolymer and its copolymer with bisphenol-based benzoxazine（Bz） was investigated. The results in- dicated that the initial thermal decomposition temperature of HCP homopolymer was 333℃ under nitrogen atmosphere, and the char yield was 42% at 800℃. The copolymer of HCP and Bz had even better thermal stability and char formation than any homopolymer of HCP and Bz,whose temperature with 5%weight-loss was 367℃ and the char yield was 52% at 800℃.
