Abstract :
A mathematical model is developed for the molecular weight distribution (IMWD) of a polyethylene terephthalate (PET) polycondensation process based on the reaction mechanisms and the operating conditions. It employs the logical combination of the reaction extent method, the moment method and the statistical fitting technique. An optimization scheme is then discussed on the tracking of the desired MWD during the polymerization process.
