Summary
-
1.
A study was made of the kinetics of the change in the composition of the products of the polycondensation of glycine ethyl ester.
-
2.
Rate constants were calculated for the consumption of monomer at different relative concentrations of carbamate, and the activation energy for the addition of monomer to peptides was calculated.
-
3.
An examination was made of the causes of the differences in the kinetics of the polycondensation of α-amino ester when initiated by carbon dioxide and when initiated by carbamate.
