This book specifically discusses the linear polymers that were intentionally made. Also, the structures presented are limited in scope considering that they are the result of the research cited in this book. However, claims that dispute a certain structure found in the research are also included to provide balance, fairness, and objectivity. Specifically, this book is a valuable resource for polymer and organic chemists. However, it can also be of great use to those scientists and researchers interested in the study of polymer chemistry of living systems.

Cycloaddition Reactions of Heterocumulenes reviews cycloaddition reactions, particularly on hetercocumulenes having'four-electron'bonds. This book discusses the chemical relationship among the various classes of heterocumulenes, including their chemical reactivity which ranges from highly reactive species to nearly inert compounds. This text also investigates the nucleophilic reactions of ketenes and isocyanates with suitable substrates, and if possible, correlates available data with the reactivity of these species in cycloaddition reactions. This book also investigates the cycloaddition reactions of carbon suboxide and other aspects of its chemistry due to the presence of many other interrelated reactions. The synthetic organic chemist should also investigate the application of isocyanate reactions associated with the cumulative double bonds. This text investigates carbodiimides as useful reagents for peptide synthesis, and notes that the stability of carbodiimides increases significantly with sterical hindrance around the cumulative double bond system. This book discusses three compounds that have a central electrophilic carbon atom, namely, carbon dioxide, carbonyl sulfide, and carbon disulfide. The book also describes the cycloaddition reactions of sulfenes, of N-sulfinylamines, of N-sulfinylsulfonamides, and of sulfurdiimides. This book can prove useful for researchers, technicians, and scientists whose works involve organic chemistry, analytical chemistry, and other related fields of chemistry.

Chemistry and Technology of Silicones retains the nature of a monograph despite its expanded scope, giving the reader in condensed form not only a wide-ranging but also a thorough review of this rapidly growing field. In contrast to some other monographs on organosilicon compounds that have appeared in the interim, the silicones occupy in this edition the central position, and the technological part of the work is entirely devoted to them. This book comprises 12 chapters, and begins with a general discussion of the chemistry and molecular structure of the silicones. The following chapters then discuss preparation of silanes with nonfunctional organic substituents; monomeric organosilicon compounds RnSiX4-n; and organosilanes with organofunctional groups. Other chapters cover preparation of polyorganosiloxanes; the polymeric organosiloxanes; other organosilicon polymers; production of technical silicone products from polyorganosiloxanes; properties of technical products; applications of technical silicone products in various branches of industry; esters of silicic acid; and analytical methods. This book will be of interest to practitioners in the fields of molecular chemistry.

Surface Active Chemicals resents a number of applications of surface activity. This book provides a discussion of bulk solution phase properties, which is important for proper understanding of surface phenomena. Organized into seven chapters, this book begins with an overview of the works of cohesion of some organic liquids and their woks of adhesion to water. This text then describes the properties of ordinary soaps, which consist of blends of alkali–metal or organic base salts of fatty acids of from eight to eighteen carbon atoms. Other chapters consider the characteristic of soapy lather by the addition of excess fatty acid to soap, which raises its proportion in the surface layer still further and tends to make the lather even creamier. This book discusses as well the processes for the extraction of bone glue. The final chapter deals with the statistics of production and sales for soaps and detergents. This book is a valuable resource for chemists and senior students.

Reaction Heats and Bond Strengths presents the variations in the heats of particular types of reaction. This book covers a variety of topics, including the hydrogenation and polymerization of olefinic compounds, the dissociation of organic and organo-metallic compounds, and the molecular-addition compounds. Organized into 10 chapters, this book begins with an overview of the concept of bond energy that can be very useful where a comparison is being made between two dissimilar molecules. This text then examines the strain in cyclopropane and cyclobutane, which is largely a result of angular strain due to compression of the tetrahedral angle in the carbon–carbon bonding. Other chapters consider the experimental thermochemical data for some conjugated molecules. This book discusses as well the significance of representing a molecule, which originated from the concept of resonance. The final chapter deals with bond strength in phosphorus, silicon, and sulfur compounds. This book is a valuable resource for postgraduate students.

The Chemistry of Heterocyclic Compounds, since its inception, has been recognized as a cornerstone of heterocyclic chemistry. Each volume attempts to discuss all aspects – properties, synthesis, reactions, physiological and industrial significance – of a specific ring system. To keep the series up-to-date, supplementary volumes covering the recent literature on each individual ring system have been published. Many ring systems (such as pyridines and oxazoles) are treated in distinct books, each consisting of separate volumes or parts dealing with different individual topics. With all authors are recognized authorities, the Chemistry of Heterocyclic Chemistry is considered worldwide as the indispensable resource for organic, bioorganic, and medicinal chemists.
