| Brief content | Seeded emulsion consists of two phases – continuous aqueous phase and dispersed polymer particles. During polymerisation radicals are created in the aqueous phase, then attack some polymer particle, where it propagates via water-insoluble monomer. There are two attributes related to emulsion polymerisation resulting from the nature of the process. First, non-equal distribution of reaction loci within a particle (higher near the edge) and, second, strict separation of particles, which makes impossible a reaction of a radical from one particle with radical or polymer in another particle. Both attributes result in limitations of some mathematical models and we will address these limitations by comparing a kinetic ODE model and kinetic Monte Carlo model. |
