【Abstract】 Conductometric titration method has been used to determine the degree of sulfonation,i.e.,the percentage of sulfonated units,in sulfonated polyphenylene oxide(SPPO) samples.Meanwhile,elemental analysis and NMR were used to confirm the results obtained by conductometric titration. Discussion of the various types of titration curves is described.更多还原
