The polymerization kinetics of DL- and L-aspartic acid, either in the absence or presence of sodium bisulfate were studied with thermogravimetric analysis. The results revealed that the polymerization of both types of aspartic acids proceeds through the dehydration in two steps, the loss of one water molecule in each step, and the presence of sodium bisulfate effectively catalyzed the polymerization.
