The mechanism of dispersion polymerization is described. The model is developed to predict the number of particles, the critical smallest size of the stable particles and the duration of the nucleation and particle formation stage. The key components of this model are a multibin coagulative nucleation theory for unstable nuclei coalescence through homogeneous nucleation and the grafting mechanism of stabilization. A critical point is defined where similar-sized particles stop coalescing with one another because the graft available equals the minimum graft required to stabilize the particles.
