phenolic hydroxyl group in the same aromatic ring was synthesized and characterized. The method includes the synthesis of polymeric benzoxazine precursors from simple chemicals such as gallic acid, gallic amide, 4,7,10-trioxa-1,13-tridecanediamine and formaldehyde by using traditional main chain synthesis methodology. The precursors were successfully characterized by the spectral and thermal investigations
摘要合成并表征了一种新型的
生物基主链苯并恶嗪,该主链具有在相同的芳环上具有两个恶嗪环和一个
酚羟基。该方法包括通过使用传统的主链合成方法,从简单的
化学物质(如
没食子酸,没食子酰胺,4,7,10-三氧杂-1,13-
十三烷二胺和
甲醛)合成聚合的苯并恶嗪前体。使用1H NMR,FTIR,
GPC,
DSC和TGA,通过光谱和热研究成功地表征了前体。结果表明,与两个恶嗪环相邻的苯环中的
酚羟基对降低苯并恶嗪的ROP温度具有很大的作用。通过在
DSC分析中以126°C的起始值追踪放热来证明ROP温度的明显降低。而且,
