以蒽醌（AQ）和均苯四甲酸酐（PMA）为原料在三氯化铝的催化作用下，对比采用溶液（硝基苯）法和熔盐（NaCl-AlCl3）法合成了具有一定介电常数的多省并醌聚合物（PAQR）。通过红外对产物进行结构表征，然后对产物进行热失重（TC）分析测试，最后测量两种方岳PAQR的介电常数。结果显示两种方法合成的PAQR热稳定性均良好：采用熔盐法得到了在20Hz频率下，介电常数为4350的PAQR，而溶液法的介电常数仅为48．5。

PAQRs （Polyacene quinone radical polymers） with certain dielectr/c constant were synthesized by anthraquinone （AQ） and pyromellitic dianhydride （PMA） with the aluminum chloride as catalyst, compared with the solution （nitrobenzene） method and the molten salt （ NaCl - AlCl3 ） method. The structures of products were identified by Fourier transform infrared spectroscopy （ FTIR） , and Thermo Gravimetric （TG） Analysis were done, finally the dielectrle constant of the PAQRs were tested. Results showed the thermal properties of both kind of PAQRs was good, and the dielectric constant was 4350 at 20 Hz with the molten salt method, while the dielectric constant was only 48.5.
