4,4-bis[5-(aminomethyl)furan-2-yl]pentanoic acid (BAFP), brand new renewable acid-containing diamines, was first utilized as feedstock for preparing fully biomass-based benzoxazine with self-catalytic characteristic. The resulting acid-containing bio-benzoxazine was prepared through Schiff base strategy. The onset ring-opening polymerization temperature of resulting benzoxazine is 173 °C determined by DSC, much lower than that of analogous bisfurfurylamine-based biobenzoxazine free of carboxylic group. The curing kinetics of as-prepared benzoxazine was probed by non-isothermal DSC method. The curing reaction consisted of three stages with overlapped regions with each other. The first stage was ascribed to initiation reaction triggered by protons of acid, with a activation energy of 116.9 KJ/mol calculated by Flynn-Wall-Ozawa method; the second stage was named combination-catalyzed stage for the fact that acid proton and phenolic proton was co-catalyzed the chain propagation, with a activation energy of 118.0 KJ/mol; The third stage was diffusion-controlled curing reaction with a activation energy of 137.3 KJ/mol. More interesting, the calculated apparent activation energy of three reactions decreased with the increase of monomer conversion.

全新的含可再生酸的新型二胺4,4-双[5-（氨基甲基）呋喃-2-基]戊酸（BAFP）首先用作制备具有自催化特性的完全基于生物质的苯并恶嗪的原料。通过Schiff碱策略制备所得的含酸生物苯并恶嗪。通过DSC测定，所得苯并恶嗪的起始开环聚合温度为173℃，远低于不含羧基的类似基于双糠胺的生物苯并恶嗪的起始温度。通过非等温DSC方法研究了所制备的苯并恶嗪的固化动力学。固化反应包括彼此重叠的三个阶段。第一阶段归因于由酸质子触发的引发反应，其活化能通过Flynn-Wall-Ozawa方法计算为116.9 KJ / mol。由于酸质子和酚质子共催化链增长，活化能为118.0 KJ / mol，第二阶段被称为组合催化阶段。第三阶段是扩散控制的固化反应，活化能为137.3 KJ / mol。更有趣的是，三个反应的表观活化能随单体转化率的增加而降低。
