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 The Organic Chemistry of Museum Objects written by Stephen G Rees-Jones and published by Elsevier. This book was released on 1987-02-24 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Organic Chemistry of Museum Objects provides an account of the composition, chemistry, and analysis of the organic materials which enter into the structures of objects in museum collections. This book is not intended to duplicate the information available in existing handbooks on the materials and techniques of art and conservation but rather to convey the state of knowledge of the chemical composition of such materials and so provide a framework for a general understanding of their properties. The book begins with a review of basic organic chemistry, covering hydrocarbons and compounds with functional groups. It then describes spectrometry and separation methods. This is followed by discussions of the chemistry and composition of oils and fats, natural waxes, bituminous materials, carbohydrates, proteins, and natural resins and lacquers. Subsequent chapters deal with synthetic materials, i.e., high molecular weight polymers of a wholly synthetic nature; and natural and synthetic dyestuffs. Also discussed are the deterioration and other changes in organic materials resulting from both free radical and ionic reactions; and the application of analytical methods to identify the organic materials of actual museum objects. This book is intended for both chemists and nonchemists.
