Commercial Polymer Blends is an in depth and unparalleled presentation of the compositions of virtually all polymer blends. Part 1 provides a short history of polymer science and technology. Part 2 summarises the reasons for, and the scientific principles of, blending and presents the current state of knowledge in the fields of interfacial properties, compatibilization, morphology, flow behaviour and performance. The chronological evolution of blend technology is presented in Parts 3 (commodity resin blends) and 4 (engineering and speciality resin blends). The text has practical value in aiding the development of new blends for specific applications. The basic text is then supplemented with four appendices, covering abbreviations, commercial blend names, examples of major blends and a summary list of patents. The text presents a systematic discussion of polymer - polymer blends of commercial interest. Evolution of each blend is traced from the very beginning to the present day, providing a description of how the blends were prepared, what compatibilizers and secondary polymeric components were added, what results were obtained, and why. The text also focuses on special functional blends, such as blends developed for the control of permeability by gases and liquids, electrostatic dissipative or electrically-conductive blends, biodegradable blends and molecular composites. In addition it discusses the recycling of polymers and polymer blends. Commercial Polymer Blends comes complete with a fully searchable PC-compatible database containing comprehensive information on: * international abbreviations for polymers and polymer processing; * polymer blends discoveries and developments (including year of patent, comments and references for each polymer blend).
