摘要： 离子性聚合物的合成方法主要集中于通过一些含芳环聚合物的大分子反应,引入不同的离子基。如聚苯乙烯、聚芳醚砜、聚芳醚酮的磺化反应及聚苯醚的羧化反应等。但伴随大分子反应,聚合物要发生严重的化学降解,并且引入离子基团数目也不易控制。

Abstract: A series of linear carboxy-containing polyaryl ether sulfones (PES) with high molecular weight were synthesized directly by using phenolphthalin as bisohenol monomer. No chemical degradation in macromolecule was observed, which is usually difficult to be avoided in preparing ion-contain-ing polymers by the traditional macromolecular reaction. Synthesis has been carried out conveniently either in acid-form or in salt-form, with a desired degree of earboxylation. The results of DSC deterruination indicated that the Tg of the acid-form of earboxylated PES decreased linearly with the increase of carboxylation degree.

Key words: polyarylethersulfone, phenolphthalin, polycondensation, ion-polymer, copolymer, synthesis
