| 摘 要： | 设计并合成了一系列含有苯并噁唑环和不同CH2链长的刚、柔间隔聚亚甲基苯并二噁唑（PBOCx）聚合物，并对它们进行了结构表征，同时对聚合物的溶解性能和热性能进行了探讨．研究表明，在主链上引入亚甲基结构可以在一定程度上提高聚合物的溶解性，其中PBOC4显示了良好的溶解性能，但随着亚甲基数目的增加，聚合物的溶解性能有下降趋势；虽然有柔性链段的引入，分解温度降低，但是PBOCx仍具有很高的热分解温度，在450℃以下表现出良好的热稳定性．

| Abstract: | In this paper, a series of PBOs polymer of containing different number of methylenes were prepared. These polymer were characterized by FT-IR, ^1HNMR spectrum and the properties of the polymer were also discussed. The results demonstrated that this polymer of containing short methylenes chains had good solubility in organic solvents such as DMF, NMP, DMSO, DMAc etc, but not very well to long ones. The result also showed good heat resistance of these polymers. |
