Abstract:

The kinetics of free radical polymerization were treated theoretically under the assumption that the reaction temperature increases at constant rate T const. From The Arrhenius relationships for the kinetic rate constants, approximate corresponding functions of time were derived, which transformed the kinetic equations accordingly. A differential equation describing the sum of the concentrations of all free radicals appearing in such a system was solved by approximation, and from the resulting series the conditions for the lower as well as the upper bound of the stationary state assumptions were obtained.
