介绍了苯并噁嗪(BZ)树脂的合成方法(溶剂法和非溶剂法),特别综述了BZ耐热、增韧改性在单体的分子结构设计、引入其他可聚合官能团、形成共混或共聚物以及加入纳米粒子等方面的研究进展。最后对BZ树脂的发展方向进行了展望。 The synthesis methods (solvent method and non-solvent method) of benzoxazine (BZ) resin are introduced. The molecular structure design of BZ heat-resistant and toughening modified monomers is introduced in detail, and other polymerizable functional groups are introduced to form blended Or copolymer as well as the introduction of nano-particles and other aspects of research. Finally, the development direction of BZ resin is prospected.
