Abstract
A method of preparing a telechelic ionomeric polyester includes reacting a first diol with a sulfoaromatic carboxylic acid salt to form a sulfoaromatic carboxylate ester salt, and reacting the sulfoaromatic carboxylate ester salt with a diester and a second diol in the presence of a transesterification catalyst to form a telechelic ionomeric polyester. Also disclosed are telechelic ionomeric polyesters.
