When dealing with challenges such as providing fire protection while considering cost, mechanical and thermal performance and simultaneously addressing increasing regulations that deal with composition of matter and life cycle issues, there are no quick, one-size-fits-all answers. Packed with comprehensive coverage, scientific approach, step-by-step directions, and a distillation of technical knowledge, the first edition of Fire Retardancy of Polymeric Materials broke new ground. It supplied a one-stop resource for the development of new fire safe materials. The editors have expanded the second edition to echo the multidisciplinary approach inherent in current flame retardancy technology and put it in a revised, more user-friendly format. More than just an update of previously covered topics, this edition discusses: additional fire retardant chemistry developments in regulations and standards new flame retardant approaches fire safety engineering modeling and fire growth phenomena The book introduces flame retardants polymer-by-polymer, supplemented by a brief overview of mode of action and interaction, and all the other ancillary issues involved in this applied field of materials science. The book delineates what, why, and how to do it, covering the fundamentals of polymer burning/combustion and how to apply these systems and chemistries to specific materials classes. It also provides suggested formulations, discusses why certain materials are preferred for particular uses or applications, and offers a starting point from which to develop fire-safe materials.

Polymers are substances containing a large number of structural units joined by the same type of linkage. These substances often form into a chain-like structure. Starch, cellulose, and rubber all possess polymeric properties. Today, the polymer industry has grown to be larger than the aluminium, copper and steel industries combined. Polymers already have a range of applications that far exceeds that of any other class of material available to man. Current applications extend from adhesives, coatings, foams, and packaging materials to textile and industrial fibres, elastomers, and structural plastics. Polymers are also used for most composites, electronic devices, biomedical devices, optical devices, and precursors for many newly developed high-tech ceramics. This new book presents leading-edge research in this rapidly-changing and evolving field.

Thermal Characterization of Polymeric Materials is a critical review and a concise evaluation of the application of thermal analysis in polymer science and engineering. This book is divided into nine chapters that specifically tackle the instrumentation, theory, and a wide variety of applications of thermal characterization. The introductory chapters provide an overview of all aspects of thermal analytical methods and apparatus and the theory underlying the basic principles of thermal analysis. These chapters also examine the theories and functions of state for thermometry, dilatometry, thermomechanical analysis, calorimetry, thermogravimetry. These topics are followed by a discussion on single-component and multicomponent systems and their phase transitions, as influenced by concentration, pressure, deformation, molecular weight, and copolymerization. The subsequent chapters explore the influence of important chemical and physical parameters on the glass transition, crystallization, and melting of thermoplastic materials. The discussion then shifts to the theoretical aspects of polymer-polymer compatibility, phase separation, and miscibility in mixed polymer systems. This book further considers the thermal analysis in thermosets, elastomers, and fibers. The concluding chapters present the methods of obtaining information on the relative flammability properties of polymers, for screening fire retardant additives, and for studying the mechanism of flame inhibition. These chapters also look into the thermal analysis of antioxidants, stabilizers, lubricants, plasticizers, impact modifiers, and fire retardants. Polymer scientists and researchers will find this book invaluable.

Thermal analysis is an old technique. It has been neglected to some degree because developments of convenient methods of measurement have been slow and teaching of the understanding of the basics of thermal analysis is often wanting. Flexible, linear macromolecules, also not as accurately simply called polymers, make up the final, third, class of molecules which only was identified in 1920. Polymers have neverbeenfullyintegratedintothedisciplinesofscienceandengineering. Thisbook is designed to teach thermal analysis and the understanding of all materials, flexible macromolecules, as well as those of the small molecules and rigid macromolecules. The macroscopic tool of inquiry is thermal analysis, and the results are linked to microscopic molecular structure and motion. Measurements of heat and mass are the two roots of quantitative science. The macroscopic heat is connected to the microscopic atomic motion, while the macroscopic mass is linked to the microscopic atomic structure. The macroscopic unitsofmeasurementofheatandmassarethejouleandthegram,chosentobeeasily discernable by the human senses. The microscopic units of motion and structure are 12 10 the picosecond (10 seconds) and the ångstrom (10 meters), chosen to fit the atomic scales. One notes a factor of 10,000 between the two atomic units when expressed in “human” units, second and gram—with one gram being equal to one cubic centimeter when considering water. Perhaps this is the reason for the much better understanding and greater interest in the structure of materials, being closer to human experience when compared to molecular motion.

This new book covers different areas of antimicrobial materials based on polymers including chitosan, polymers with ammonium and phosphonium groups, polymer nanofibers, carbon-based polymer Nanocomposites, polymeric and non-polymeric metal complexes, and biomimetic materials. By combining the information of different materials as well as antimicrobial action modes and applications within one source, the book provides a general summary of the field. Polymeric Materials with Antimicrobial Activity starts with a general introduction to antimicrobial polymers and presents the most common types of microorganisms (bacteria, fungi, yeast and algae) along with the main areas of application of antimicrobial polymeric materials. Specific chapters then detail different polymer systems covering the fundamental issues of synthesis, characterization, physico-chemical properties and applications. With contributions from leading scientists the book is suitable for researchers in polymers, chemistry, biology and materials science interested in an overview of antimicrobial polymeric materials as well as the recent advances in their synthesis, properties and applications.

This book considers general aspects of the theory of polymers applied in optics. The main factors affecting the light loss in polymeric wave beam guides (PG) are discussed, and the mechanism of light loss in PG is analysed. Polymers applied in fiber optics are classified with reference to methods of fabrication and purification of the materials. Technological aspects of material fabrication are considered together with kinetic aspects of polymerisation. Updated information on polymerisation kinetics of MMA and styrene, and copolymerisation of these monomers with each other is reported. Other topics discussed in the book are heterogeneity of optic copolymers, association between structure and reactivity of monomers, other properties of optic copolymers, and areas of their commercial application. This volume will be of value and interest to anyone working in the field of optic polymers, both in academia and industry.
