Book Description
Photodegradation and light stabilization are very important aspects of polymer aging. Polymer degradation includes different types of processes: thermodegradation, oxidation, acting of ozone, photodegradation, radiation, hydrolysis, mechanical degradation, and biodegradation. It is very important to know the mechanism of polymer degradation in order to select stabilizers against the degradation. This volume presents the analysis of achievements in the field of photodegradation of polymers. It includes, first of all, data of Russian investigators who have decisively contributed in the development of this field of knowledge (the schools headed by academicians V.V. Korshak, N.M. Emanuel, N.S. Enikolopov, A.A. Berlin, and many others).

Book Description
Photochemical reactions are the main class of chemical processes. These processes provide for life on Earth, since due to photochemical processes, plants absorb carbon oxide from the atmosphere changing them into the "meal" for all creatures on Earth. Together with "good" photochemical processes there are some "bad" as well. This book is about photodestruction and light stabilisation and is devoted to these processes. For example, the heterochain polymers. They are the main class of large-tonnage polymers, which are used for manning a great variety of polymer and composite materials (including nanocomposites).

Book Description
During the last two decades, the production of polymers and plastics has been increasing rapidly. In spite of developing new polymers and polymeric materials, only 40~60 are used commercially on a large scale. It has been estimated that half of the annual production of polymers is employed outdoors. The photochemical instability of most polymers limits their outdoor application as they are photodegraded quickly over periods from months to a few years. To the despair of technologists and consumers alike, photodegradation and environmental ageing of polymers occur much faster than can be expected from knowledge collected in laboratories. In order to improve polymer photostability there has been a very big effort during the last 30 years to understand the mechanisms involved in photodegradation and environmental ageing. This book represents the author's attempt, based on his 25 years' experience in research on photodegradation and photo stabilization, to collect and generalize a number of available data on the photodegradation of polymers. The space limitation and the tremendous number of publications in the past two decades have made a detailed presentation of all important results and data difficult. The author apologizes to those whose work has not been quoted or widely presented in this book. Because many published results are very often contradictory, it has been difficult to present a fully critical review of collected knowledge, without antagonizing authors. For that reason, all available theories, mechanisms and different suggestions have been presented together, and only practice can evaluate which of them are valid.

Book Description
This two-volume work examines general relationships among the structures, reactivity, and properties of polyamides important for predictions in such fields as materials science. The team of authors, including polymer research chemists, physicists, and specialists in technology and processing, compiled an extensive amount of literature (over 2300 references) to produce two volumes packed with text, tables, drawings, and first-hand information, much of it never before published. Topics include lactams and their production, properties, analysis, theory, and the technology of their polymerization, in addition to polyamides and their processing, modification, analysis, molecular characterization, structure, physical properties, degradation and stabilization, designing and application of products. Researchers and specialists in the preparation, modification, processing, structure, and properties of linear aliphatic polyamides will find Lactam-Based Polyamides, Volumes I and II to be invaluable texts.
