苯并嗪化合物是以酚类化合物、胺类化合物和甲醛为原料合成的六元杂环．在适当条件下能发生开环聚合反应，生成类似于酚醛树脂结构的材料，固化过程无低分子挥发成份放出，因而作为酚醛树脂高性能化的新途径，日益受到人们的重视并得到了应用［１～３］．苯并嗪化合物... Benzoxazin compounds are phenolic compounds, amine compounds and formaldehyde as raw materials six-membered heterocyclic ring. Under appropriate conditions, ring-opening polymerization can take place to form a material similar to the phenolic resin structure, and no low-molecular-weight volatile components are released during the curing process. Therefore, as a new way of high-performance phenolic resin, more and more attention has been paid to the use of phenolic resin [ 1 ~ 3]. Benzoxazine compound ...
