Available in PDF, EPUB and Kindle. Book excerpt: This thesis is a contribution to the development of population balance models of emulsion polymerization and, more particularly, to the modeling of particle formation and particle size distribution (PSD) in vinyl chloride emulsion polymerization. The rst part of the work is dedicated to the acquisition of experimental data. Ab initio polymerizations were done to obtain reliable data regarding the dependence of the particle number on the concentration of surfactant, as well as to analyze the effect of the initiator concentration, stirring rate, and monomer-to-water ratio upon the particle number and the polymerization kinetics. In addition, seeded polymerizations were carried out at different concentrations of seed latex and emulsifier in order to quantify the influence of these factors on the onset and extent of secondary particle formation. Moreover, the adsorption isotherms of SDS and SDBS on poly (vinyl chloride) latex particles were determined. The second part of the manuscript focuses on the development of the population balance model. A special feature of the model proposed in this work is the computation of the coupled radical number and particle size distributions by the zero-one-two population balance equations. Overall, the examples presented show that the model can capture the tendencies observed in the polymerizations with physically reasonable values of the unknown/ adjustable parameters. With respect to particle formation, it was seen that including the possibility of particle nucleation (homogeneous and micellar) by exited radicals helps to explain the high particle numbers observed and the fact that the initiator concentration has a negligible effect on the particle number. Moreover, it was demonstrated that particle coagulation must be taken into account in order to obtain plausible PSDs and to avoid the use of abnormally low values of the efficiency of radical entry into micelles. In the third and last part, two novel numerical methods for the solution of population balances of interest to emulsion polymerization systems are presented and discussed.

Book excerpt: This book provides a modern overview of the principles governing emulsion polymerization, a topic of both academic and industrial importance. The reader is provided with the mathematical, physical and technical tools to understand the mechanisms and physical chemistry of these systems, particularly the major advances of the last 15 years. The book describes the mechanisms that govern the various aspects of an emulsion polymerization, and how from appropriate experimental studies, the dominant mechanisms in a particular system may be deduced. From such deductions, the means are developed whereby the properties of the result of the emulsion polymerization can be quantitatively modelled and trends can be qualitatively understood and predicted. This book opens the way to the intelligent, knowledge-based design that is the future for improvements and innovations in products and processes from this important technology. Provides a thoroughly up-to-date overview of the principles and practices of emulsion polymerization Contains mathematical, physical, and technical tools which enable the reader to understand the mechanisms and physical chemistry used in the field Includes extensive exercises with model answers

Available in PDF, EPUB and Kindle. Book excerpt: Chemistry and Technology of Emulsion Polymerisation 2e provides a practical and intuitive explanation of emulsion polymerization, in combination with both conventional and controlled radical polymerization. For those working in industry, coupling theory with everyday practice can be difficult. By carefully explaining the principles of the reaction, based on well-designed experimental investigation, the book explains how the principles relate to practical application. The second edition of this book includes a new chapter on morphology of latex particles, a rapidly progressing area where modelling the thermodynamic and kinetic aspects of phase separation and morphology has developed into a mature and powerful tool to predict and control morphology of latex particles. Another area that is rapidly progressing is the application of controlled radical polymerisation in emulsion polymerization. Controlled radical polymerisation is used in aiding encapsulation of inorganic particles like pigment particles and clay platelets. These latest developments are included in the second edition.

Available in PDF, EPUB and Kindle. Book excerpt: 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”. Modeling emulsion polymerization systems requires modeling the particle size distribution (PSD), which is an important end-use property of the latex. This PSD includes submodels dedicated to particle nucleation, mass transfer between the different phases (monomer, radicals, stabilizer), and particle coagulation. These models should preferably be individually identified and validated experimentally. The first main part of the work is dedicated to the experimental study. This part can be divided in three parts. The first part describes the adsorption of inorganic particles on polymer without reaction. Multilayer adsorption was observed and B.E.T. isotherm was able to describe this adsorption. The adsorption was found to be enhanced at higher ionic strength. The adsorption dynamics were found fast and therefore clay partitioning can be considered at equilibrium during polymerization. The second part concerned the investigation of different reaction parameters on the particles number and reaction rate in ab initio polymerizations. The effect of mixing, initial monomer concentration and initiator concentration were considered. Optimization of these conditions was useful for the modeling part. The last part described the differences between several LaponiteR_ grades through the ab initio emulsion polymerization of styrene. The second main part of the manuscript focused on the modeling of the Pickering emulsion polymerization. The population balance model and average number of radicals balance were adapted regarding the effect of inxi organic particles. The growth of the polymer particles was optimized by fitting the models of radicals' entry and desorption described available in literature to the experimental data. No modification was needed, which allowed us to conclude that the clay had no influence on radical exchange. However, LaponiteR_ stabilization played an important role in polymer particles production. Coagulative nucleation model was able to describe the nucleation rate and predict the total number of particles.
