The population balance methods are employed to model sulfur vulcanization process of
natural rubber (NR) compounds. The proposed primary models are so far empirical and/
or mechanistic and have various limitations that do not embody all reactions and formation
of all the process products. In this work, the models are developed, using population
balance methods that explicitly acknowledge the nature of all the formed species and the
various types of reactions. The kinetic model can also accurately describe the complete
cure responses including the scorch delay, cure time and the reversion for a wide range of
compositions, using a single set of rate constants. In addition, the concentration profiles
of all the reaction intermediates as a function of polysulfidic lengths are predicted. The
population balance model provides a quantitative framework for explicitly incorporating
mechanistically reasonable chemistry of the vulcanization process of different natural
rubber compounds.
