About the Author
Dr. John Scheirs has worked extensively with PET and related polyesters. His early work involved studying the UV stability of PET and PEN in France and later he was involved with studying various industrial problems involving polyesters such as photodegradation, annealing, crystallization behaviour, embrittlement, degradation by aminolysis, DSC analysis, environmental stress cracking, hydrolysis, nucleating agents, transesterification, injection moulding of recycled PET compounds, solid state polycondensation, desiccant drying of PET and melt stabilization of PET. More recently in the period 1998-2000, he was the technical manager for Coca-Cola Amatil's world first PET reforming plant which converts post-consumer PET bottles into high-grade, high IV pelletized PET for direct reuse in new bottles and injection and sheet moulding applications. John Scheirs is now the principal consultant with ExcelPlas Polymer Technology where he specializes in polymer recycling, chemistry, formulation, processing and testing.
