摘　　要：以蒽醌(AQ)和均苯四甲酸二酐(PMA)为原料,在路易斯酸的催化作用下,采用固态加热法、熔盐法和溶剂热法合成了多省并醌聚合物(PAQR)。通过X射线衍射(XRD)、傅里叶红外光谱(FTIR)和热重分析(TG)以及元素分析仪分析了产物的结构,并利用阻抗分析仪研究了该聚合物的性能。结果表明:由熔盐法合成的PAQR具有更高的产率,达42%;采用溶剂热法合成的聚合物具有最高的聚合度和共轭程度,且介电性能较好。Polyacene quinone radical polymer（PAQR） was synthesized by solid-state heating method, molten salt method and solvothermal method with anthraquinone（AQ） and pyromellitic dianhydride（PMA） as raw materials, and lewis acid as the catalyst. The structure of PAQR was analyzed by X-ray diffraction（XRD）, Fourier transform infrared spectroscopy（FTIR）, thermogravimetric analysis（TG） and element analyzer. The properties of PAQR were investigated through impedance analyzer. The results show that the PAQR synthesized by molten salt method can provide the higher yield, up to 42%. Meanwhile, the polymer synthesized by solvothermal method has the highest polymerization degree and conjugation degree, and the better dielectric property.
