以腰果酚、己二胺、多聚甲醛为原料,合成腰果酚己二胺型苯并口恶嗪中间体,采用FT-IR,1 H NMR对其结构进行表征。用差示扫描量热(DSC)法研究自由基引发剂、催化剂对其固化行为的影响。结果表明:加入自由基引发剂后,脂肪族长链中的双键先发生聚合反应,然后口恶嗪环再开环聚合;单乙醇胺对中间体的固化有明显的促进作用;所得聚合物的耐热温度指数为195℃。 Cardanol, hexamethylenediamine and paraformaldehyde were used as raw materials to synthesize the benzoxazine intermediates of hexamethylenediamine hexamethylenediamine. Their structures were characterized by FT-IR and 1 H NMR. Differential scanning calorimetry (DSC) was used to study the influence of free radical initiator and catalyst on its curing behavior. The results showed that after the addition of free radical initiator, the double bond in the aliphatic long chain first undergoes polymerization reaction, and then the oxazine ring is ring-opened and polymerized again. Monoethanolamine obviously accelerates the curing of the intermediate; the resistance of the obtained polymer The thermal temperature index is 195 ° C.
