This book, the second edition of the first monograph fully devoted to UV degradation and stabilization ever published in English, has 12 chapters discussing different aspects of UV related phenomena occurring when polymeric materials are exposed to UV radiation. In the introduction the existing literature has been reviewed to find out how plants, animals and humans protect themselves against UV radiation. This review permits evaluation of mechanisms of protection against UV used by living things and potential application of these mechanisms in protection of natural and synthetic polymeric materials. This is followed by chapters with a more detailed look at more specific aspects of UV degradation and stabilization. A practical and up-to-date reference guide for engineers and scientists designing with plastics, and formulating plastics materialsExplains the effects of UV light on plastics, and how to mitigate its effects through the use of UV stabilizersSurveys the range of UV stabilizers on the market, and provides advice on their selection and use INDICE: 1. Introduction2. Photophysics and photochemistry3. Mechanisms of UV stabilization4. UV stabilizers (chemical composition, physical-chemical properties, UV absorption, forms, applications - polymers and final products, concentrations used)5. Stability of UV stabilizers6. Principles of stabilizer selection7. UV degradation and stabilization of polymers and rubbers (description according to the following outline: mechanisms and results of degradation, mechanisms and results of stabilization, and data on activation wavelength (spectral sensitivity), products of degradation, typical results of photodegradation, most important stabilizers, concentration of stabilizers in formulation, and examples of lifetime of typical polymeric materials)8. UV degradation and stabilization of industrial products (description according to the following outline: requirements, lifetime expectations, important changes and mechanisms, stabilization methods)9 Focus on technology - Sunscreen 10 UV stabilizers and other components of formulation 11 Analytical methods in UV degradation and stabilization studies12 UV stabilizers - health & safety
