摘要

正

A novel polyetheretherketone （PEK-C） prepared from phenolphthalein has been synthesized. In order to improve some of its properties for application in high performance membrane

the PEK-C has been sulfonated with concentrated sulfuric acid. Degree of sulfonation can be regulated by controlling the temmperature and time of sulfonation. The characterization of the sulfonated PEK-C in sodium salt form has been made by IR

H NMR and

C NMR etc. It is shown that the sulfonation appears to take place exclusively in the ortho position to phenolic ether of phenolphthalein unit. The result is in agreement with theoretical deduction. Some properties of the sulfonated PEK-C

such as solubility

transition temperature

thermal degradation and hydrophilicity have also been discussed.
