PVC stabilization, the most important aspect of formulation and performance of this polymer, is discussed in details. This book contains all information required to design successful stabilization formula for any product made out of PVC. Separate chapters review information on chemical structure, PVC manufacturing technology, morphology, degradation by thermal energy, UV, gamma, other forms of radiation, mechanodegradation, and chemical degradation. The chapter on analytical methods used in studying of degradative and stabilization processes helps in establishing system of checking results of stabilization with different stabilizing systems. Stabilization and stabilizers are discussed in full detail in the most important chapter of this book. The final chapter contains information on the effects of PVC and its additives on health, safety and environment. This book contains analysis of all essential papers and patents published until recently on the above subject. It either locates the answers to relevant questions and offers solutions or gives references in which such answers can be found. PVC Degradation and Stabilization is must to have for chemists, engineers, scientists, university teachers and students, designers, material scientists, environmental chemists, and lawyers who work with polyvinyl chloride and its additives or have any interest in these products. This book is the one authoritative source on the subject. A practical and up-to-date reference guide for engineers and scientists designing with PVC Covers thermal, UV, gamma radiation, chemical, and other forms of degradation Includes a critical discussion of the sustainability issues faced by PVC and its additives, as well as health and safety concerns

The development of polymers as an important class of material was inhibited at the first by the premature failure of these versatile compounds in many applications. The deterioration of important properties of both natural and synthetic polymers is the result of irreversible changes in composition and structure of polymers molecules. As a result of these reactions, mechanical, electrical and/or aesthetic properties are degraded beyond acceptable limits. It is now generally recognized that stabilization against degradation is necessary if the useful life of polymers is to be extended sufficiently to meet design requirements for long-term applications. Polymers degrade by a wide variety of mechanisms, several of which affect all polymers through to varying degree. This monograph will concentrate on those degradation mechanisms which result from reactions of polymers with oxygen in its various forms and which are accelerated by heat and/or radiation. Those stabilization mechanisms are discussed which are based on an understanding of degradation reaction mechanisms that are reasonably well established. The stabilization of polymers is still undergoing a transition from an art to a science as mechanisms of degradation become more fully developed. A scientific approach to stabilization can only be approached when there is an understanding of the reactions that lead to degradation. Stabilization against biodegradation and burning will not be discussed since there is not a clear understanding of how polymers degrade under these conditions.

Ever since the beginning of the plastics and rubber industry, it was realized that useful products could be produced only if cer tain additives were incorporated into polymers. With the help of these additives, when physically dispersed in a polymer matrix, it has been possible to improve stability against thermal, oxidative, UV, hydrolytic and biological degradation, mechanical properties, flammability, cost, and processibility of plastics. The enormous growth of the volume of plastics consumed by modern society, and new application areas for plastics, have created a demand for new, better additives and better understanding of their functions in polymer systems. As a result of these trends there is a need for sharing of information on progress achieved in the area of polymer additives among engineers and scientists of the plastics industry and academia. This book is based on expanded and updated papers originally presented at the International Symposium on Polymer Additives, which was held in Las Vegas, Nevada, and was sponsored by the American Chemical Society, Division of Polymeric Materials Science and Engi neering. The book is divided into five parts which cover advances in various areas of polymer additives. The first part is devoted to the progress in understanding of UV degradation and stabilization of various polymers. Oxidation degradation and stabilization of plastic materials is covered in the second part. New developments in the stabilization of PVC are presented in the third part.

In spite of extensive efforts, material weathering testing still requires improvement. This book presents findings and opinions of experts in material degradation testing. The aim is to improve testing methods and procedures. Materials are presented to show that photochemical degradation rate depends on a combination of environmental factors such as UV radiation, temperature, humidity, rain, stress, and concentration of reactive pollutants. The potential effect of each parameter of degradation on data gathered is discussed based on known results from a long experience in testing. This book contains data obtained in laboratories of the largest manufacturers of UV stabilizers and chemical companies that manufacture durable materials. The book gives details of testing procedures and choice of parameters of exposure which are crucial for obtaining laboratory results correlating with environmental performance of materials. In addition to exposure conditions, the book contains many suggestions on sample preparation and post-exposure testing. The effective use of these methods shortens testing time of materials and determines acceleration rate of testing. The book also gives examples of complete, well-designed weathering experiments which may be used as patterns for selection of parameters and techniques for new studies. The areas of research that still require more attention in future studies are clearly indicated.

PVC differs in its stabilization compared to other commodity plastics. Various metal compounds are suitable for the stabilization of PVC: lead, tin, calcium, magnesium, zinc, rare earths, and also almost-metal-free systems. These differences are described in the introductory part of this book, with their advantages, possibilities, and problems, from the perspective of the chemist but made understandable for salespeople and technicians. Numerous tables and figures are included, providing structures and physico-chemical data. A special section for beginners is dedicated to guiding formulations and test methods. A relatively short section deals with development trends in Europe. Sustainability is a major theme, and it is demonstrated that PVC has a strong potential to develop into a fully sustainable material. Another section deals with the everyday problems in the processing of PVC, such as the formation of specks, photo-effects, and plate-out. Plate-out is a common problem in the processing of PVC but only relatively few publications cover it. The causes, influencing factors, and mechanisms are still poorly understood. This section, unique in the literature, provides assistance in the selection and dosage of raw materials to PVC processor, based on the influencing factors during processing.
