Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

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.
