This intensive study course deals with the basic factors controlling particle morphology in synthetic latices used for coatings, adhesives, impact modifiers and biomedical applications. It is intended for scientists and engineers involved in product development and latex processing operations. Thermodynamic principles are applied to investigate the effect of experimental recipe and process variables. Computer simulations are used to design latex particles and analyze the morphology via TEM. Non-equilibrium morphologies and emulsion polymerization kinetics are treated in detail through experimental design and computer simulation. Participants will complete a case study and must be familiar with operating computers in a window environment. As a result of this course, participants should be able to more readily develop improved products and cost effective processes.Limited enrollment of 24.Course directors are Dr. Donald Sundberg, Dr. John Tsavalas and Dr. Jeffrey Stubbs. Duration : 3.5 days
