This book describes the latest developments in paper conservation by using polymeric materials. A short introduction on polymer chemistry is given to highlight the polymer characteristics and properties. The book is then dedicated to the conservative problems and issues in the field of paper artworks. This practical book identifies the importance of each type of polymer, related to its nature and properties, from the point of view of paper conservation. With the help of schemes and tables, the polymers are classified in terms of characteristics and final uses in respect to this very complex material.

This handbook is dedicated to the conservation of stone materials by the application of polymers. A short introduction on polymer chemistry is given to highlight their characteristics and properties. After the physical and chemical attributes of stone are summarised, the problems related to its degradation are discussed. Finally, the properties of the various polymers of potential value for stone restoration are reviewed and classified by schemes and tables, and pointers for the future are suggested.This handbook will be of great interest to those who share the author's enthusiasm for stone artworks and her dedication to their restoration and conservation.

Biopolymer and Biopolymer Blends: Fundamentals, Processes, and Emerging Applications showcases the potential of biopolymers as alternative sources to conventional nonbiodegradable petroleum-based polymers. It discusses fundamentals of biopolymers and biopolymer blends from natural and synthetic sources, synthesis, and characterization. It also describes development of desired performance for specific applications in 3D printing and other emerging applications in industry, including packaging, pulp and paper, agriculture, biomedical, and marine. Introduces the fundamentals, synthesis, processing, and structural and functional properties of biopolymers and biopolymer blends. Explains the fundamental framework of biopolymer blends in 3D printing, featuring current technologies, printing materials, and commercialization of biopolymers in 3D printing. Reviews emerging applications, including active food packaging, electronic, antimicrobial, environmental, and more. Discusses current challenges and futures prospects. Providing readers with a detailed overview of the latest advances in the field and a wealth of applications, this work will appeal to researchers in materials science and engineering, biotechnology, and related disciplines.

Plastic objects are included more than ever in museums and galleries collections these days, but these items can start to deteriorate when they a just a few years old. In this book Yvonne Shashoua provides the essential knowledge needed to keep plastic pieces in the best possible condition so that they can continue to be enjoyed for many years. The historical development of plastics, as well as the technology, their physical and chemical properties, identification, degradation and conservation are all clearly and concisely covered within this single volume, making it an invaluable reference for the increasing number of conservators and curators that are encountering plastics in their day to day work.

A resource for the photographic conservator, conservation scientist, curator, as well as professional collector, this volume synthesizes both the masses of research that has been completed to date and the international standards that have been established on the subject.

Materials in Conservation is the definitive introduction to the properties of materials used in conservation. The continual struggle of conservators to ameliorate the deterioration of objects has led to increasing use of synthetic polymers. These materials are part of the sophisticated technology that has been developed to augment and often replace traditional materials and methods. Conservators therefore have a wider range of techniques available. However, they must be able to appreciate the potentials and pitfalls of any proposed technique. The first section explains physical and chemical properties which are important in the conservation process, i.e. application, ageing, reversal. The topics covered include molecular weight, glass transition temperature, solubility and solvents, polymerisation and degradation reactions. The second section provides a detailed consideration of the individual materials, current and obsolete, used in conservation, drawing out the factors relevant to their effects on objects. The conservation uses of each material are summarised and referenced to allow further study. In five appendices, the properties of the polymers, solvents and their interactions are tabulated, with a list of suppliers and conversion table of physical units. IUPAC and SI nomenclature is used throughout the book. In this second edition, this classic text is revised and updated to include modern materials such as cyclododecane, and current ideas on adhesion, consolidation and reversibility, making Materials in Conservation the definitive source of vital information in the field. This handy reference book should be on the bench of every conservator and available wherever objects, from steam engines to dried plants, are preserved.

This report is the result of a three-year research program. It describes the chemical character of cellulose ethers as a general class of polymers and establishes an approximate ranking of the relative stability of each generic chemical subclass. Ranking the thermal stability of the polymers with respect to color change and loss in degree of polymerization led to the conclusion that as generic chemical classes, methylcellulose and carboxymethylcellulose appear to be the most stable of the cellulose ethers. Water-soluble ethylhydroxyethylcellulose apparently also possesses good stability. Of questionable long-term stability are hydroxyethylcellulose and hydroxy- propylcellulose. Ethylcellulose and organic-soluble ethylhydroxyethylcellulose proved to be of poor stability, potentially undergoing marked changes in twenty years or less under normal museum conditions. An important additional conclusion reached here, as well as in an earlier investigation, is that considerable variations in stability can occur within a generic chemical class from differences in the basic raw material, a natural product from plants, which is not a uniform, manufactured, chemical substance. Further variations can exist due to different manufacturing processes or commercial sources. Hence, commercial products must be evaluated individually to determine the most stable of a given generic type. Nonetheless, the authors believe the conclusions expressed here to be valid with regard to the relative stability of the generic chemical classes of cellulose ethers.

D.R. Brothwell and A.M. Pollard have got together to create the first large scale review of the many sciences which contribute to modern archaeology for over 30 years. The Handbook of Archaeological Sciences is intended to bring together a substantial overview of the sciences in archaeology in one complete volume. The book is organised under eight broad headings: dating, quaternary palaeoenvironments, human palaeobiology, developments in biomolecular archaeology, resource exploitation, archaeological prospection, conservation science in the archaeological context and statistical and computer applications. The contributors, who are all well-known in their own areas of expertise, bring together in each chapter the basic science and the relevance of this science to the overall goal of archaeology - understanding humans in the past. This book is an invaluable source of reference for those interested in archaeology, anthropology, quaternary studies, geography, palaeoecology, computing, biology, chemistry and physics, those involved in commercial and local authority field archaeology units, museums and archaeological organisations.
