Book Synopsis Polymer Photodegradation by : J.F. Rabek
Download or read book Polymer Photodegradation written by J.F. Rabek and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 679 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Photostabilization of Polymers by : J.F. Rabek
Download or read book Photostabilization of Polymers written by J.F. Rabek and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. Increasing the stability of polymers and plastics towards heat, light, atmospheric oxygen and other environmental agents and weathering conditions has always been a very important problem. The photochemical instability of most of polymers limits them to outdoor application, where they are photo degraded fast over periods ranging from months to a few years. To the despair of technologists and consumers alike, photodegrada tion and environmental ageing of polymers occur much faster than can be expected from knowledge collected in laboratories. In many cases, improved methods of preparation and purification of both monomers and polymers yield products of better quality and higher resistance to heat and light. However, without stabilization of polymers by applica tion of antioxidants (to decrease thermal oxidative degradation) and photostabilizers (to decrease photo-oxidative degradation) it would be impossible to employ polymers and plastics in everyday use.

Book Synopsis Photophysical and Photochemical Properties of Aromatic Compounds by : Jacob Malkin
Download or read book Photophysical and Photochemical Properties of Aromatic Compounds written by Jacob Malkin and published by CRC Press. This book was released on 1992-06-10 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photophysical and Photochemical Properties of Aromatic Compounds is the first book to collect and classify all available quantitative data on the photochemistry and luminescence of aromatic compounds. Compounds are classified by both spectral-luminescent (e.g., extinction coefficients, energies and lifetimes of lower excited states) and photochemical properties. In addition, all of the quantum yields available have been collected. The variety of photochemical reactions of aromatics is examined based on eight types of elementary monomolecular and bimolecular photochemical processes. Aromatic compounds are grouped into eight categories, and the book analyzes the possibilities of occurrence of all types of elementary photoprocesses.

Book Synopsis Current Topics in Polymer Research by : Robert K. Bregg
Download or read book Current Topics in Polymer Research written by Robert K. Bregg and published by Nova Publishers. This book was released on 2005 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book presents leading-edge research in this rapidly-changing and evolving field.

Book Synopsis Effects of Light on Materials in Collections by : Terry T. Schaeffer
Download or read book Effects of Light on Materials in Collections written by Terry T. Schaeffer and published by Getty Publications. This book was released on 2001-08-16 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of light on works of art and archival materials has long been an issue of concern to conservators and other museum professionals, yet the literature on this subject has never been systematically reviewed. This volume fills that gap by providing a survey of the impact of exposure to light with an emphasis on photoflash and reprographic sources. The information provided will assist the professional audience, especially conservators and collections managers, in assessing the risk to art and archival objects of such exposures. The text surveys relevant photophysical and photochemical principles, photometric and radiometric measurement, and the spectral outputs of several light sources. Materials discussed include colorants and natural fibers; pulp, paper, and wood; natural and synthetic polymers; fluorescent whitening agents; photographic and reprographic materials; and objects containing combinations of materials. Approximations and assumptions used in the evaluation process are discussed in some detail, with examples of the different types of calculations. The Research in Conservation reference series presents the findings of research conducted by the Getty Conservation Institute and its individual and institutional research partners, as well as state-of-the-art reviews of conservation literature. Each volume covers a topic of current interest to conservators and conservation scientists.
