Annual Core-Shell Latex Morphology Workshop

Next workshop will be held June 2-5, 2014 at The University of New Hampshire

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 for this year are Dr. Donald Sundberg Dr. John Tsavalas and Dr. Jeffrey Stubbs (of DSM Neoresins).

Duration : 3.5 days

This course is now organized by EPCEd (Emulsion Polymers Consulting & Education) and all registration will be processed by EPCEd.
