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。
In this paper, hexa-cyclophoronediphosphazene, 1,1’-dihydroxybiphenyl, p-hydroxybenzoate and benzoxazine monomers with active functional groups were synthesized. Benzoxazine oxazine monomer (HCP). The FT-IR, 1 H-NMR, 13 C-NMR, and 31 P-NMR spectra were used to characterize their curing behavior and the copolymers of HCP homopolymer and HCP with bisphenol A benzoxazine resin (Bz) Thermal performance. The results showed that the initial thermal decomposition temperature of HCP homopolymer was 333 ℃ under nitrogen atmosphere, and 42% carbon residue at 800 ℃. The initial thermal decomposition temperature of HCP / Bz copolymer is 367 ℃, and the carbon residue rate at 800 ℃ is 52%. The HCP / Bz copolymer has better thermal stability and carbon formation than HCP and Bz homopolymer.
