本文采用对氨基酚、苯酚和甲醛为原料合成了一种新型的苯并口恶嗪中间体。运用FTIR和１H－NMR对中间体结构进行了表征。并采用１H－NMR方法研究了反应条件对中间体结构的影响，结果表明在70～90℃下反应1～2h有利于形成口恶嗪环。同时，对该中间体的固化反应进行了研究，表明该中间体具有较高的反应活性，并能够促进苯并口恶嗪树脂的固化反应进行。

A novel kind of benzoxazine precursors was synthesized from p-aminophenol，phenol and formaldehyde，and characterized by FTIR and １H－NMR．The relation of reaction conditions to APPF precursors′ structure was studied by １H－NMR，and the results showed that the reaction time of 1～2h gave more oxazine rings．The curing reactivity of the precursors was also studied．It was found that the precursors were highly reactive and could accelerat the curing reaction of benzoxazines．
