The ring‐opening reaction of p‐cresol‐based 1,3‐benzoxazine with amine at room temperature was investigated in different solvents. Results show that the reactions proceeded easily in protic solvents, but no reaction occurred in aprotic solvents. For different amines involved in the reactions, both primary and secondary amines can participate in the reaction with benzoxazine, while tertiary amines would hinder the progress of the nucleophilic reaction. The mechanism study demonstrated the feasibility of polymerization of the benzoxazine with amines at room temperature. Moreover, the crosslinking between bifunctional benzoxazine and diamine was realized at room temperature, and the polymer can be obtained.

室温下3,4-二氢-2H-1,3-苯并恶嗪与胺的开环反应

在不同溶剂中研究了对甲酚基1,3-苯并恶嗪与胺在室温下的开环反应。结果表明，在质子传递溶剂中反应易于进行，但在质子传递溶剂中未发生反应。对于参与反应的不同胺，伯胺和仲胺都可以参与与苯并恶嗪的反应，而叔胺会阻碍亲核反应的进行。机理研究证明了室温下苯并恶嗪与胺聚合的可行性。另外，在室温下实现了双官能的苯并恶嗪与二胺的交联，可以得到聚合物。
