The stability and resistance of polymeric materials determine whether they can be utilized in a given application. Authoritative and reliable material information is needed during the material selection process and this information must consider the influences of material manufacturing, compounding and stabilization, processing, part design, use and subsequent disposal/recycling. This book is based on the review of more than 1200 literature sources and represents a comprehensive overview of the current know-how regarding the stability and resistance of thermoplastics, thermosets, elastomers as well as the most commonly used reinforcements and additives. Extensive tables document material resistance to given media, facilitating appropriate material selection or stabilization for a given application. Contents Volume 1: Principles of Aging Testing Methods Stabilization Influence of Processing and Use Resistance to Thermal and Thermal-Oxidative Loads, Weathering, Chemicals, Ionizing Radiation, Microorganisms, Biological Influences, and Mechanical Loads Creep and Fatigue of Reinforced Polymers Contents Volume 2: Chemical Resistance Tables White Lists of Media Influence (According to DIBt) References Index
The contents have been divided into sections on physical states of polymers and characterization techniques. Chapters on physical states include discussions of the rubber elastic state, the glassy state, melts and concentrated solutions, the crystalline state, and the mesomorphic state. Characterization techniques described are molecular spectroscopy and scattering techniques.
Definitions of what is meant by a heat-resistant polymer vary considerably. We have taken the term to mean a polymer which can be used, at least for short time periods, at temperatures from 150°C. The greatest problem which arises in writing a monograph on such materials is the tremendous amount of data that is available. More than 2000 references have been published on one heat-resistant polymer system alone over a period of little more than two years. The result is that a very high degree of selectivity must be exercised with respect to the information reproduced. We have chosen to restrict our coverage to polymers that have received at least some degree of commercial exploitation and to details of their methods of preparation, their thermal and thermo-oxidative stabilities and modes of degradation, and their properties at elevated temperatures. It must be emphasized that other properties not cited, e. g. , hydrolytic and chemical stability, and resistance to ultraviolet radiation, may be equally important in particular uses of these materials. The "older" heat-resistant polymers, e. g. , the thermosets and some of the fluorine-containing materials, are not dealt with in such depth as are the "newer" polymers with aromatic and/or heterocyclic rings in the chain. This is because books have been available for some time on the well-established commercial polymers and developments in them have not been as marked re cently as in the aromatic and heterocyclic macromolecules.
Understanding the thermal degradation of polymers is of paramount importance for developing a rational technology of polymer processing and higher-temperature applications. Controlling degradation requires understanding of many different phenomena, including chemical mechanisms, the influence of polymer morphology, the complexities of oxidation chemistry, and the effects of stabilisers, fillers and other additives. This book offers a wealth of information for polymer researchers and processors requiring an understanding of the implications of thermal degradation on material and product performance.

Covers the main theoretical and practical problems involved in radiation chemistry of polymers. The processes of polymerization and modification of polymers induced by ionizing radiation, are described, as well as the radiation resistance of polymers and their protection from radiation.
Corrosion of Polymers and Elastomers provides a detailed examination of the corrosive effects of thermoplastic polymers, thermoset polymers, and elastomeric materials. The book is perfectly suited for specialists interested in the corrosion resistance and mechanisms of these materials. Following a general introduction to the composition, properties, and applications of polymers, the book focuses on the effects of chemical corrosion caused by changes in temperature, moisture, and other corrodents. Organized by material type, the chapters cover each material's ability to withstand sun, weather, and ozone as well as its chemical resistance and typical applications. The book also includes compatibility tables for each of the materials and compares the corrosion resistance of selected elastomers.
The explores the cutting-edge technology of polymer coatings. It discusses fundamentals, fabrication strategies, characterization techniques, and allied applications in fields such as corrosion, food, pharmaceutical, biomedical systems and electronics. It also discusses a few new innovative self-healing, antimicrobial and superhydrophobic polymer coatings. Current industrial applications and possible potential activities are also discussed.
