摘要

聚合动力学是高分子化学理论教学的重点及难点，但与之对应的动力学实验教学，因受教学学时、实验硬件等条件的限制，一直是一个薄弱环节。特别是热固性树脂的固化动力学实验，基本上在本科阶段没有涉及。本文利用可再生资源香草醛和呋喃甲胺为主要原料，采用绿色溶剂乙醇制备了生物基苯并噁嗪，利用差示扫描量热仪(DSC)研究了苯并噁嗪的固化动力学，确定了固化反应的活化能、反应机理和静态固化工艺。本文展示：国产DSC设备所获得实验结果基本满足本科实验教学要求，为该实验项目的推广创造了条件。

Abstract

Though polymerization dynamics is the key point during the teaching of polymer chemistry

the corresponding dynamic experiments for undergraduates hasn’t caught necessary attentions due to the limitation of teaching hours and experimental hardware conditions. In particular

the curing dynamic experiments of thermosetting resin are basically not involved in the undergraduate stage. In this article

using renewable vanillin and furfurylamine as the feedstocks

a bio-benzoxazine was prepared and its curing kinetics

activation energy

reaction mechanism and static curing technology were studied by differential scanning calorimetry (DSC). The results obtained by the domestic DSC equipment basically meet the requirements of the undergraduate experimental teaching

which creates enough chances for the promotion of the designed project described in this article.
