摘　　要：两种单体 2 ,2′ ,6 ,6′ 四甲基 4 ,4′ 二苯氧基二苯酮 (o M2 DPOBP)和 2 ,2′ ,6 ,6′ 四甲基 4 ,4′ 二苯氧基三苯二酮 (o M2 DPOTPDK) ,分别与对苯二甲酰氯 (TPC)和间苯二甲酰氯 (IPC)低温亲电溶液缩聚 ,合成了 4种含双邻位甲基侧基聚醚酮醚酮酮 (DM PEKEKK和DM PEKEKMK)及含双邻位甲基侧基聚醚酮酮醚酮酮 (DM PEKKEKK和DM PEKKEKMK)聚合物 .用FT IR、1 H NMR、DSC、TGA、WAXD等方法对聚合物进行了表征 ,研究了聚合物的溶解性能 .结果表明 ,该 4种聚合物具有较高的玻璃化转变温度 ,良好的热稳定性和优良的溶解性能 .Four novel poly(aryl ether-ketone-ether-ketone-ketone)s (DM-PEKEKK, DM-PEKEKMK) and poly(aryl ether-ketone-ketone-ether-ketone-ketone)(s) ( DM-PEKKEKK, DM-PEKKEMK), containing his (o-methyl) moiety were prepared by electrophilic polycondensation of 2, 2', 6, 6'-tetramethyl-4, 4'-diphenoxydiphenylketone (o-M2DPOBP) or 2, 2', 6, 6'-tetramethyl-4, 4'-diphenoxytriphenyldiketone (o-M2DPOTPDK) and terephthaloyl chloride (TPC) or isophthaloyl chloride (IPC) in 1, 2-dichloroethane and in the presence of AlCl3 and DMF. The polymers were characterized by FT-IR, WAXD, DSC, 1H-NMR, TGA and there solubility properties were tested. The results show that the polymers have high glass transition temperature, good thermostabilities and excellent solubilities.
