摘要

两种单体 2

2′

6′-四甲基-4

4′-二苯氧基二苯酮 (o-M2DPOBP)和 2

2′

6′-四甲基-4

4′-二苯氧基三苯二酮 (o-M2DPOTPDK)

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、1H-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.

Abstract

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 bis(o-methyl) moiety were prepared by electrophilic polycondensation of 2

2’

6'-tetramethyl-4

4'-diphenoxydiphenylketone (o-M2DPOBP) or 2

2’

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 slass transition temperature

good thermostabilities and excellent solubilities.
