By proposing a recognized kinetic mechanism of the amide interchange reaction, where aminolysis plays the controlling role, a deterministic model dealing with the kinetic behavior of the hydrolytic polymerization of ε‐caprolactam including the amide interchange reactions can be established. The rate equations in terms of moments were derived by applying the Z ‐transform technique and solved by the Runge–Kutta method. It was found that the presence of the amide interchange reaction led to a shorter equilibration time than otherwise would be the case. The results from this new model were found to be quite consistent with the experimental data reported by Tai.
