A series of benzoxazine monomers containing maleimide have been prepared from hydroxyphenylmaleimide,formaldehyde,and different amine derivatives including aniline,4,4’-diaminodiphenyl methane,and aminophenyl propargyl ether. Highly thermostable polybenzoxazines were obtained by the thermal cure of the monomers.

5.以含马来酰亚胺基团的苯酚和甲醛为原料,采用不同的胺（包括苯胺、二苯甲烷二胺和4-炔丙基醚基苯胺）反应合成了三种新型的含马来酰亚胺基团的苯并恶嗪中间体,并通过加热聚合得到了高耐热的聚苯并恶嗪。

Chapter 2 refers to the synthesis of benzoxazine monomers. According to the flexibility of molecular design of benzoxazine, four benzoxazine monomers were designed and synthesized.

在单体合成上,利用苯并恶嗪灵活的分子设计性,分别合成了四种苯并恶嗪单体。
