The values are relatively high when compared with the B-a/epoxy thermoset, which possesses 5% degradation temperature at 302-309, dependent on the curing catalyst [32]. Unlike the curing of neat ( 6) (Fig. 2), the characteristic peaks of oxazine did not disappear completely in the ( 6)/DCPDE system after curing at 220 C for 20 min, suggesting a slower curing rate. The carbonyl signal, which was not seen after 140 C treatment, supports the formation of cyclic amide. In contrast to the good solubility of ( 6), preparing benzoxazine ( 7) in chloroform (Run 8) and toluene/ethanol (Runs 9e10) results in powder precipitate (not gelation) after 1 h due to the poor solubility of ( 7), which limits the purity of ( 7). |

The values are relatively high when compared with the B-a/epoxy thermoset, which possesses 5% degradation temperature at 302-309, dependent on the curing catalyst [32]. 与B-a/环氧热凝物相比，这些数值相对较高。 在固化促进剂的作用下，B-a/环氧热凝物在302-309度的温度区间，发生5%的热降解。 Unlike the curing of neat ( 6) (Fig. 2), the characteristic peaks of oxazine did not disappear completely in the ( 6)/DCPDE system after curing at 220 C for 20 min, suggesting a slower curing rate. 与图2中整齐固化不同的是，在220摄氏度的环境中，经过20分钟的固化后，恶嗪的特征峰不会从DCPDE 系统中完全消失。 The carbonyl signal, which was not seen after 140 C treatment, supports the formation of cyclic amide. 羰基信号（在经过140摄氏度的热处理后会消失，或者不可见）能促进环酰胺的形成。 In contrast to the good solubility of ( 6), preparing benzoxazine ( 7) in chloroform (Run 8) and toluene/ethanol (Runs 9e10) results in powder precipitate (not gelation) after 1 h due to the poor solubility of ( 7), which limits the purity of ( 7). 与（6）良好的溶解度形成对比的是， 在氯仿（Run 8）和甲苯/乙醇（Runs 9e10)中，制备苯并恶嗪，会在1小时后， 由于（7）的溶解度较差，产生粉末沉淀物（非胶凝态），这制约了（7）纯度的提升。 |
