AbstractCarboxylated 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 AB2 monomer, 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.Carboxylated poly(arylene ether ketone)s with hyperbranched and linear architectures were synthesized by the self-condensations of aromatic dicarboxylic anhydrides.

通过芳族二羧酸酐的自缩合合成具有超支化和线性结构的羧化聚(亚芳基醚酮)

摘要 通过芳族二羧酸酐的自缩合反应合成了具有超支化和线性结构的羧化聚亚芳基醚酮。由 AB 单体 4-苯氧基邻苯二甲酸酐获得线性聚(亚芳基醚酮),而使用 AB2 单体 1,3-双(3,4-二羧基苯氧基)苯二酐获得超支化聚(亚芳基醚酮) . 超支化聚(亚芳基醚酮)的合成方法值得注意,因为它通过一锅缩聚提供了高于 7 mmol g-1 的高离子交换能力。与典型的聚(醚酮)相比,这些功能性聚合物可溶于多种有机溶剂和 NaOH 水溶液,同时它们保持其主链的高热稳定性。通过芳族二羧酸酐的自缩合合成了具有超支化和线性结构的羧化聚(亚芳基醚酮)。由 AB 单体 4-苯氧基邻苯二甲酸酐获得线性聚(亚芳基醚酮),而使用 AB2 单体 1,3-双(3,4-二羧基苯氧基)苯二酐获得超支化聚(亚芳基醚酮) . 超支化聚(亚芳基醚酮)的合成方法值得注意,因为它通过一锅缩聚提供了高于 7 mmol g-1 的高离子交换能力。而超支化聚(亚芳基醚酮)是使用 AB2 单体 1,3-双(3,4-二羧基苯氧基)苯二酐获得的。超支化聚(亚芳基醚酮)的合成方法值得注意,因为它通过一锅缩聚提供了高于 7 mmol g-1 的高离子交换能力。而超支化聚(亚芳基醚酮)是使用 AB2 单体 1,3-双(3,4-二羧基苯氧基)苯二酐获得的。超支化聚(亚芳基醚酮)的合成方法值得注意,因为它通过一锅缩聚提供了高于 7 mmol g-1 的高离子交换能力。
