Cellulose is the principal constituent of all plant life; it is the most abundant, important and fascinating biopolymer on earth. Cellulose, as an almost inexhaustible, environmentally benign and renewable material, has stimulated basic and applied research as well as inspired significant progress in Polymer Science. In recent years, cellulose has gained renewed importance as a raw material. Although ground breaking research is carried out on cellulose, it still possesses high potential for future applications; it can be easily modified to more natural and sustainable alternatives compared to synthetic products by certain techniques. The present book reviews some vital issues and topics on the latest science and technological advances in cellulose and its derivatives. This catalog acts as an essential source of information to readers in the exploration for possible applications of cellulose and its derivatives. The authors hope this collection will spark a generation of new ideas for product development. The present book contains 25 invited contributions written by leading experts in the field of cellulose and cellulose derivatives. It is divided into three parts: Part I, Cellulose Synthesis and Modification; Part II, Cellulose Derivatives; and Part III, Applications of Cellulose Derivatives. Highlights of this book include the mechanism of cellulose formation in biosynthetical processes; surface modification and functionalization of cellulose fibers; advances in the homogenous and heterogeneous phase modification of cellulose to create unusual and functional derivatives; analysis and characterization of modified derivatives; derivatives for antimicrobial, medical and pharmaceutical applications, and wastewater treatment; dendronized and hyperbranched cellulose derivatives; and rheology of nanocellulosic systems.

This book summarizes recent progress in cellulose chemistry. The last 10 years have witnessed important developments, because sustainability is a major concern. Biodegradable cellulose derivatives, in particular esters and ethers, are employed on a large scale. The recent developments in cellulose chemistry include unconventional methods for the synthesis of derivatives, introduction of novel solvents, e.g. ionic liquids, novel approaches to regioselective derivatization of cellulose, preparation of nano-particles and nano-composites for specific applications. These new developments are discussed comprehensively. This book is aimed at researchers and professionals working on cellulose and its derivatives. It fills an important gap in teaching, because most organic chemistry textbooks concentrate on the relatively simple chemistry of mono- and disaccharides. The chemistry and, more importantly, the applications of cellulose are only concisely mentioned.

"The first section explains the physical and chemical properties which are important in the conservation process, i.e. application, aging, reversal. The topics covered include molecular weight, glass transition temperature, solubility and solvents, polymerisation and degradation reactions, adhesion, and uses. The second section provides 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"--P. [4] of cover.

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.

How to Find Out About Patents presents a basic knowledge of patent matters and provides a few facts regarding patent law and procedures. This book provides a description of the literature available for finding out about patents followed by a comprehensive consideration of the techniques used to obtain any desired information from this. Organized into 15 chapters, this book starts with an overview of the procedure and the requirements of obtaining a patent wherein the inventor usually goes to a patent agent who drafts a patent specification and files this at the Patent Office. This text then explains the patent specification, which is the fundamental document of patent literature and is a statement of the nature of the invention. Other chapters consider the main value of the Patent Journal to industry, which is indispensable as a record of any week's activity at the Patent Office. The final chapter deals with the establishment of a patents department in an industrial company's organization. This book is a valuable resource for professional patent agents.
