Abstract project PICKEP
The aim of the present project is to develop a methodology for fundamental modeling of surfactant-free emulsion polymerization processes stabilized by inorganic particles, referred to as “Pickering emulsion polymerization (PickEP)”. The model should be able to describe the reaction kinetics in the different phases, mass transfer between phases (ex. radicals) and the evolution of the particle size distribution (PSD), which is an important end-use property of the latex. The sought model will be based on individual fundamental sub-models representing particle nucleation, growth, coagulation, mass transfer, partitioning of inorganic particles and the reaction kinetics in the different phases. Sub-models are autonomous pieces that are individually identified and validated experimentally representing an elementary mechanism. The obtained model will improve process understanding and can be used in control strategies in order to improve the product quality, mainly to increase the solid contents of the latex for industrial interest.
