摘　　要：以甲氧基次甲基二苯醚低聚物为基础合成了苯并口恶嗪预聚物（ＢＯＤＰＯ），用Ｈ－ＮＭＲ、ＩＲ表征了该预聚物的结构，讨论了反应温度、溶剂的极性等因素对合成预聚物的结构和组成的影响。研究结果表明，ＢＯＤＰＯ预聚物的成环率在９０％以上，预聚物的组成，在很大程度上依赖于反应介质或溶剂的极性。A New type of benzoxzine precursors was systhesized based on methoxy methylene diphenyl ether oligomer.The struture of product was characterized by IR and H-NMR analysis and effects of solvent polarity,temperature on the precursor composition were investigated.The results obtained show that ring content in the composition is more than 80%, the composition of the precursors depended upon mainly the polarity of the reaction medium or solvent.
