Summary

  1. 1.

    The kinetics of the consumption of glycine ethyl ester during its polycondensation in the presence of carbon dioxide were studied.

     
  2. 2.

    The first stage of the polycondensation is the formation of carbamate.

     
  3. 3.

    The rate of monomer consumption does not depend on the method by which the original reaction mixture is formed, i.e. by the addition of carbon dioxide or the immediate introduction of carbamate.

     
  4. 4.

    A hypothesis is put forward on the autocatalytic nature of the binding of glycine ethyl ester during its polycondensation in the presence of carbon dioxide.
