摘　　要：采用无溶剂法和有溶剂法分别合成了一种新型的苯并恶嗪预聚体 ,通过核磁共振氢谱、傅立叶红外光谱和差示扫描量热分析对苯并恶嗪预聚体的结构和固化行为进行了研究。并以苯并恶嗪预聚体为胶液、无碱玻璃布为基材 ,经浸胶、烘焙、压制制得一种玻璃布层压板。该层压板具有优良的力学性能、耐热性能、电绝缘性能。A novel benzoxazine(BZ) precursor was synthesized successfully both in the solvent toluene and solventless. Its structure was characterized by FT-IR, 1H-NMR and the curing behavior of BZ was investigated using DSC. A new glass cloth laminate was prepared by using benzoxazine as liquid cement, alkali-free glass cloth as backing material, and treating with cement dipping, baking and pressing. The laminate had good mechanical properties, heat resistance, electric insulation, water proofness, and corrosion resistance.
