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.
