This book was released on 1999 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research describes the synthesis of an ester functionalized 2,3-disubstituted diene, 2,3-bis(4-ethoxy-4-oxobutyl)-1,3-butadiene, to produce and modify functional polymers. The polymer was synthesized via free-radical bulk and solution polymerizations. The polarity of the material, high thermal and thermooxidative stability and the ability to modify the functionality are attractive and potentially useful features. Potential applications include new polymer blends, dispersants, and membranes. Modification of polystyrene-butadiene rubber is also possible. The addition of this polymer into a variety of these materials could alter the adhesion, solubility and processing leading to tailor-made materials.

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.

Download or read book A Clinical Guide to Inherited Metabolic Diseases written by Joe T. R. Clarke and published by Cambridge University Press. This book was released on 2005-12-08 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This user-friendly clinical handbook provides a clear and concise overview of how to go about recognizing and diagnosing inherited metabolic diseases. The reader is led through the diagnostic process from the identification of those features of an illness suggesting that it might be metabolic through the selection of appropriate laboratory investigation to a final diagnosis. The book is organized into chapters according to the most prominent presenting problem of patients with inherited metabolic diseases: neurologic, hepatic, cardiac, metabolic acidosis, dysmorphism, and acute catastrophic illness in the newborn. It also includes chapters on general principles, laboratory investigation, neonatal screening, and the principles of treatment. This new edition includes much greater depth on mitochondrial disease and congenital disorders of glycosylation. The chapters on neurological syndrome and newborn screening are greatly expanded, as are those on laboratory investigation and treatment, to take account of the very latest technological developments.
Download or read book The Investigation of Organic Reactions and Their Mechanisms written by Howard Maskill and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: A range of alternative mechanisms can usually be postulated for most organic chemical reactions, and identification of the most likely requires detailed investigation. Investigation of Organic Reactions and their Mechanisms will serve as a guide for the trained chemist who needs to characterise an organic chemical reaction and investigate its mechanism, but who is not an expert in physical organic chemistry. Such an investigation will lead to an understanding of which bonds are broken, which are made, and the order in which these processes happen. This information and knowledge of the associated kinetic and thermodynamic parameters are central to the development of safe, efficient, and profitable industrial chemical processes, and to extending the synthetic utility of new chemical reactions in chemical and pharmaceutical manufacturing, and academic environments. Written as a coherent account of the principal methods currently used in mechanistic investigations, at a level accessible to academic researchers and graduate chemists in industry, the book is highly practical in approach. The contributing authors, an international group of expert practitioners of the techniques covered, illustrate their contributions by examples from their own research and from the relevant wider chemical literature. The book covers basic aspects such as product analysis, kinetics, catalysis, and investigation of reactive intermediates. It also includes material on significant recent developments, e.g. computational chemistry, calorimetry, and electrochemistry, in addition to topics of high current industrial relevance, e.g. reactions in multiphase systems, and synthetically useful reactions involving free radicals and catalysis by organometallic compounds.

Download or read book Inherited Metabolic Disease in Adults written by Carla E. M. Hollak and published by Oxford University Press. This book was released on 2016 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: As clinical management of inherited metabolic diseases (IMDs) has improved, more patients affected by these conditions are surviving into adulthood. This trend, coupled with the widespread recognition that IMDs can present differently and for the first time during adulthood, makes the need for a working knowledge of these diseases more important than ever. Inherited Metabolic Disease in Adults offers an authoritative clinical guide to the adult manifestations of these challenging and myriad conditions. These include both the classic pediatric-onset conditions and a number of new diseases that can manifest at any age. It is the first book to give a clear and concise overview of how this group of conditions affects adult patients, a that topic will become a growing imperative for physicians across primary and specialized care.
