| Abstract: | The mathematical solution of the equations derived from a kinetic scheme previously developed for donor–acceptor complex polymerization was based on steady-state conditions and the applicability of initial concentration conditions over a range of conversion. These assumptions are scrutinized and tested by computer simulation and by the exact differential equations utilizing Runge-Kutta method. The analysis shows that for case I conditions of low concentration of complexing-agent, the degree of conversion is not critical and that the previous approximate solutions are valid. The steady-state and non-steady-state conditions are compared, and the range of validity of the assumptions is established. The approximate solutions are found inapplicable in the instances of non-steady-state conditions coupled with a low concentration of either monomer. |
