摘要：

A water-soluble wholly aromatic polyketone modified with sodium carboxylate (PK-COONa) was synthesized through demethylation of the wholly aromatic polyketone bearing four methoxy groups per repeat unit (PK-OMe) followed by ethoxycarbonylmethylation and saponification. The obtained polyketones, i.e., the methyl-cleaved analogue (PR-OH), the ethoxy carbonyl group-bearing analogue (PK-COOEt), the sodium carboxylate analogue (PK-COONa), and the carboxy group-bearing analogue (PK-COOH), have varying solubilities in water and common organic solvents and thermal stabilities, depending on the functional groups.
