以合成的1,3,5-三(p-羟基苯基)苯(TP)、烯丙基胺和甲醛为原料,合成了一种新型的含烯丙基的三元酚型苯并噁嗪单体---1,3,5-三(3-烯丙基-3,4-二氢-2H-1,3-苯并噁嗪基)苯(tp-ala).采用核磁共振谱、傅里叶变换红外光谱、紫外-可见吸收光谱和差示扫描量热表征了tp-ala的结构和固化行为,用热失重分析、动态热机械分析和荧光光谱测试了固化物 P-tp-ala 的热性能及光学性能.结果表明,烯丙基的引入使P-tp-ala玻璃化转变温度高达322℃,5%的热失重温度为351℃,800℃残炭率达到61.4%,与不含烯丙基的三元酚型苯并噁嗪相比具有较好的耐热性.在233 nm激发波长下, P-tp-ala的荧光发射波长为350 nm,具有荧光性能.由于P-tp-ala中的芳香含量高,使其折射率高达1.6325,在防折射涂层方面有很好的应用潜力.

1,3,5-Tri(3-allyl-3,4-dihydro-2H-1,3-benzoxa-zinyl)benzene(tp-ala) was synthesized using allyl amine, para-formaldehyde and new synthesized 1,3,5-tri(p-hydroxyl-phenyl)benzene. The chemical structure of tp-ala was characterized by nuclear magnetic resonance spectroscopy( 1 H NMR, 13 C NMR) , Fourier trans-form infrared spectroscopy ( FTIR ) and ultraviolet and visible absorption spectroscopy ( UV-Vis ) . The curing behavior of tp-ala was studied by differential scanning calorimetry ( DSC ) analysis. The thermal and optical properties of cured tp-ala( P-tp-ala) were observed. The results showed that by introducing the allyl-group, the Tg of P-tp-ala was 322 ℃. 5% mass loss temperature was at 356 ℃ and the char yield at 800 ℃ was 61. 4%, which were higher than those of the reported trisphenol-based polybenzoxazines. P-tp-ala also showed photoluminescent property. The fluorescence emission wavelength of P-tp-ala under an excitation at 233 nm was at 350 nm. In addition, due to the high aromatic content of P-tp-ala, P-tp-ala had a high refractive index of 1. 6325 . The high refractive-index characteristic makes P-tp-ala thermoset a potential candidate in antire-flective coating.
