A sulfonated telechelic polycarbonate is described which is produced by melt synthesis. A dihydroxy compound is reacted with a sulfobenzoic acid salt, then with an activated carbonate. The method results in a sulfonated telechelic polycarbonate which has a high percentage of sulfonated end groups, is soluble, and is transparent.

Abstract

A sulfonated telechelic polycarbonate is described which is produced by melt synthesis. A dihydroxy compound is reacted with a sulfobenzoic acid salt, then with an activated carbonate. The method results in a sulfonated telechelic polycarbonate which has a high percentage of sulfonated end groups, is soluble, and is transparent.
