Metallocene-Based Polyolefins

John Scheirs has worked extensively with poly and related polyesters. His early work involved studying the UV stability of PET and poly- ethylene naphthalate - in France and later he was involved with studying various industrial problems involving polyesters, such as photodegradation, annealing, crystallization behaviour, embrittlement, degradation by aminolysis, differential scanning calorimetry 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 palletized 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.

The manufacture of polyolefins by metallocene catalysts represents a revolution in the polymer industry. The first, patent for a metallocene catalyst was filed in 1980 but it has been the last five years that have seen a dramatic increase in the volume of research into metallocenes and the maturing of metallocene technology. With contributions from leading experts from the US, Canada, Italy, Scandinavia, Germany and Japan, Metallocene-based Polyolefins gives comprehensive coverage of all areas of metallocene technology: catalyst structure, comonomer incorporation, polymerization mechanisms and conditions, reactor configurations, special properties, rheological and processing behaviour, comparison with conventional polyolefins and fields of application. An essential book for plastics engineers, polymer chemists, physicists, materials scientists and all those working in the plastics manufacturing and processing industries.
