通过芳族二羧酸酐的自缩合反应合成了具有超支化和线型结构的羧基化聚芳醚酮。以AB型单体4-苯氧基邻苯二甲酸酐为原料合成了线型聚芳醚酮，以AB型单体1，3-双（3，4-二羧基苯氧基）苯二酐为原料合成了超支化聚芳醚酮。用于合成超支化聚（亚芳基醚酮）的方法是值得注意的，因为它通过一锅缩聚提供了高于7 mmol g-1的高离子交换容量。这些功能性聚合物可溶于几种有机溶剂和NaOH水溶液中，与典型的聚（醚酮）相反，同时它们保留了其主链的高热稳定性。
Carboxylated poly(arylene ether ketone)s with hyperbranched and linear architectures were synthesized by the self-condensations of aromatic dicarboxylic anhydrides. A linear poly(arylene ether ketone) was obtained from an AB monomer, 4-phenoxyphthalic anhydride, whereas a hyperbranched poly(arylene ether ketone) was obtained using an AB2monomer, 1,3-bis(3,4-dicarboxyphenoxy)benzene dianhydride. The method for the synthesis of the hyperbranched poly(arylene ether ketone) is notable, because it provides a high ion-exchange capacity, above 7 mmol g−1, through a one-pot polycondensation. These functional polymers are soluble in several organic solvents and aqueous NaOH, in contrast to typical poly(ether ketone)s, while they retain the high thermal stabilities of their backbones.
