Book Description
The development of photosensitive materials in general and photoreactive polymers in particular is responsible for major advances in the information, imaging, and electronic industries. Computer parts manufacturing, information storage, and book and magazine publishing all depend on photoreactive polymer systems. The photo-and radiation-induced processes in polymers are also active areas of research. New information on the preparation and properties of com mercially available photosensitive systems is constantly being acquired. The recent demand for environmentally safe solvent-free and water-soluble materials also motivated changes in the composition of photopolymers and photoresists. The interest in holographic recording media for head-up displays, light scanners, and data recording stimulated development of reconfigurable and visible light sensitive materials. Photoconductive polymerizable coatings are being tested in electrostatic proofing and color printing. The list of available initiators, poly meric binders, and other coating ingredients is continually evolving to respond to the requirements of low component loss (low diffusivity) and the high rate of photochemical reactions.

Book Description
Photochemical Processes in Polymer Chemistry-2 contains invited lectures presented at the Second IUPAC Symposium on Photochemical Processes in Polymer Chemistry held at Leuven, Belgium on June 2-4, 1976. This book contains 11 papers separated as chapters. Topics include energy transfer processes; photoinitiation of polymerization; solid-state polymerization mechanisms; photoinduced ionic polymerizations; and photoconductive polymers. This text also discusses energy transfer phenomena in high polymer systems; laser spectroscopical methods for the study of primary processes during the photodegradation; photooxidation of high polymers; and reaction selectivity and molecular association in photochemical reactions of nucleic acids and their constituents. New developments in photochromic polymers and related phenomena, as well as the design of photoreactive polymer systems for imaging processes are also explained.

Book Description
Presents the state of the technology, from fundamentals to new materials and applications Today's electronic devices, computers, solar cells, printing, imaging, copying, and recording technology, to name a few, all owe a debt to our growing understanding of the photophysics and photochemistry of polymeric materials. This book draws together, analyzes, and presents our current understanding of polymer photochemistry and photophysics. In addition to exploring materials, mechanisms, processes, and properties, the handbook also highlights the latest applications in the field and points to new developments on the horizon. Photochemistry and Photophysics of Polymer Materials is divided into seventeen chapters, including: Optical and luminescent properties and applications of metal complex-based polymers Photoinitiators for free radical polymerization reactions Photovoltaic polymer materials Photoimaging and lithographic processes in polymers Photostabilization of polymer materials Photodegradation processes in polymeric materials Each chapter, written by one or more leading experts and pioneers in the field, incorporates all the latest findings and developments as well as the authors' own personal insights and perspectives. References guide readers to the literature for further investigation of individual topics. Together, the contributions represent a series of major developments in the polymer world in which light and its energy have been put to valuable use. Not only does this reference capture our current state of knowledge, but it also provides the foundation for new research and the development of new materials and new applications.

Book Description
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.

Book Description
Photochemical processes form the basis of life. Energy transfer through photons also underlies a wide range of phenomena ranging from the motion of atoms and molecules to the assembly of systems of molecules, such as polymers, Langmuir-Blodgett films and even liquid crystals. Photochemical Processes in Organized Molecular Systems provides an overview of recent photochemical investigations of systems of molecules. The book is divided into four parts: the first two deal with current progress on the understanding of photoinduced chemical processes, the third and fourth chapter deal with the photochemistry of organized molecular systems including polymers, micelles and liquid crystals. This book should be studied by all who want to know more about this promising field of photochemical research, and about the fascinating processes that light can bring about.
