摘要
A process of making a sulfonated telechelic polycarbonate is described. A dihydroxy compound, a carbonate ester, and an activated ester of a sulfobenzoic acid salt are reacted together. The method results in a sulfonated telechelic polycarbonate which has a high percentage of sulfonated end groups, is soluble, and is transparent.
