中文摘要：

选取六种不同酚源的烯丙胺型苯并噁嗪，研究苯并噁嗪官能团结构上不同取代基团对此类苯并噁嗪中间体的性质及其树脂热性能的影响。FT-IR测试结果显示，取代基团影响噁嗪环的特征吸收峰值，噁嗪环特征峰随场／诱导效应常数的增大而降低。同时，场／诱导效应的增大降低了苯并噁嗪中间体中官能团的反应温度。通过DMTA和TG分析了六种聚苯并噁嗪树脂，结果显示，场／诱导效应的增大虽能增大噁嗪树脂的残碳率，但降低了噁嗪树脂的耐热性能和热稳定性。

英文摘要：

Six allylamine-benzoxazines synthesized from different phenols were chosen to study in the article. It is confirmed that different substituents which gear into the benzoxazine functional structures have a regularity influence on benzoxazines and their polymers, among them the most important of the substituent effect is field/induction effect. The FT-IR results indicate that substituents influence the position of absorbing peak. DSC thermograms display that the exothermic temperatures are increased with a decrease in the field/induction effect constants. DMTA and TG were also used to analyse the substituent effect. It demonstrates that the field/induction effect constants have a direct proportion relationship with the polybenzoxazines char yield, but the thermal stability and the heat durability decrease with an increase in the field/induction effect constants.
