  Primary Amine-Functional Benzoxazine Monomers and Their Use for Amide-Containing Monomeric Benzoxazines

  摘要：

  Amino-functional benzoxazine monomers have been successfully prepared. Several routes have been applied to incorporate amino group into benzoxazine structure. These approaches include reduction of the corresponding nitro-functional benzoxazines and deprotection of protected amino-functional benzoxazine monomers. Various approaches that allow primary amine groups to be prepared without damaging the existing benzoxazine groups have been evaluated. Tetrachlorophthalimide and trifluoroacetyl are found to be suitable protecting groups. In addition, a model compound of amide-functional benzoxazines is prepared from primary amine-functional benzoxazine. Fourier transform infrared spectroscopy (FTIR) and H-1 and C-13 nuclear magnetic resonance spectroscopy (NMR) are used to characterize the structure of the monomers. The polymerization behavior of amino-functional monomers and model compound are studied by differential scanning calorimetry (DSC).

  cross-linked polybenzoxazole without the harmful consequences of traditional polybenzoxazole synthesis, such as the use of poly(phosphoric acid) as solvent. By this smart conversion, the flame-retardant oxazole moieties are successfully incorporated into the network structure. Further advantages of this new route for cross-linked polybenzoxazoles include outstanding flexibility in molecular design,

  在众多已知的高性能聚合物中，聚苯并恶唑（PBO）作为最耐热的多杂环聚合物已占据突出的位置。但是，PBO已在相当有限的各种技术中找到了应用，这些技术主要以纤维的形式出现。本文中，我们报告了我们的开创性工作，该工作使用新近开发的智能级苯并恶嗪树脂作为前体，通过新颖的途径生产了交联的聚苯并恶唑。这类苯并恶嗪在一个分子中都具有多种智能功能。最吸引人的特点是它的结构转变成热稳定性更高的交联聚苯并恶唑，而没有传统的聚苯并恶唑合成的有害后果，例如使用聚磷酸作为溶剂。通过这种明智的转换，阻燃的恶唑部分已成功地并入网络结构。这种用于交联聚苯并恶唑的新方法的其他优点包括在分子设计，成本效益和易加工性方面的出色灵活性。
