This comprehensive reference work is intended for use by practising professional engineers and materials scientists engaged in research and development. For ease of access to the information contained within the book, the physical properties of polymers are discussed and arranged under the following main headings: thermodynamics, spectroscopic, mechanical, electro-optical, and magnetic properties, as well as the morphology, structure, and surfaces of polymers. Methods of synthesis and chemical properties are not included. This is intended as a handbook for polymer engineers, chemical engineers, material scientists, polymer physicists, rheologists, chemical physicists, chemists, and theorists.
