ABSTRACT

There are various ways to determine the parameters of the kinetics of the cure reaction. The parameters to consider are: the cure enthalpy, which is the heat evolved from the overall cure reaction; the order of the reaction which is concerned with the concentration of active agent remaining free during the reaction at time t; and the two parameters that allow defining of the effect of the temperature on the rate of the reaction, that is, the energy of activation and a constant that depends only on the compound, by following the Arrhenius expression. Thus, by considering all these parameters, the cure of rubbers is considered a simple reaction.
