Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of the 1960s, the coordinative polymerization of conjugated dienes has continuously improved. Today, chemists know how to polymerize conjugated dienes stereospecifically and in a controlled fashion, both petro-sourced (nowadays also bio-sourced) and those of natural origin. The industry has greatly improved the performances of the catalytic systems—covering a wide range of elements including metals from groups 4–6 and 8–10, and rare earths—with the aim of optimizing the preparation of synthetic polymers for a large range of industrial applications. Nowadays, there is a better understanding of the polymerization mechanism involving allyl-active species, thanks in particular to the support of more efficient calculation methods. In addition, statistical copolymerization of 1,3-dienes with olefin or styrene comonomers and innovative approaches to coordinative chain transfer polymerization allow the production of copolymers with controlled topology, while a last challenge is about to be solved with the preparation of stereoregular polydienes that are also end-functionalized. This issue brings together several important aspects of this chemistry that remain at the forefront of both academic and industrial research.

Available in PDF, EPUB and Kindle. Book excerpt: Ziegler-Natta Catalysts and Polymerizations reviews the general aspects of Ziegler-Natta catalysts and polymerizations of olefins, dienes, and many other types of monomers. Topics covered include the physical state of the polymer during polymerization; modification of Ziegler-Natta catalysts by third components; and termination of polymer chain growth. The oxidation state of catalysts and active centers is also discussed, along with copolymerizations and block polymerizations. This book is comprised of 23 chapters and begins with an overview of Ziegler-Natta catalysts and polymerizations, their historical origins, scientific and commercial importance, and major advances in polymer science. The next chapter focuses on definitions and stereochemistry of Ziegler-Natta catalysts, together with analytical methods used to identify and quantitatively measure their structures. Some of the polymers produced commercially with Ziegler-Natta catalysts are considered. The discussion then turns to mechanisms for initiating and propagating olefins; mechanisms for stereochemical control of conjugated and nonconjugated dienes; and the basic kinetic parameters that characterize Ziegler-Natta polymerizations. This monograph is written especially for chemistry and engineering graduate students and for industrial chemists, engineers, and managers who may become involved in a Ziegler-Natta problem.

Available in PDF, EPUB and Kindle. Book excerpt: During the past 30 years, the field of alkene polymerization over transition metal catalysts underwent several major changes:1. The list of commercial heterogeneous Ziegler-Natta catalysts for the synthesis of polyethylene and stereoregular polyolefins was completely renewed affording an unprecedented degree of control over the polymer structure.2. Research devoted to metallocene and other soluble transition-metal catalysis has vastly expanded and has shifted toward complexes of transition metals with multidentate ligands.3. Recent developments in gel permeation chromatography, temperature-rising fractionation, and crystallization fractionation provided the first reliable information about differences between various active centers in transition-metal catalysts.4. A rapid development of high-resolution 13C NMR spectroscopy resulted in greatly expanded understanding of the chemical and steric features of polyolefins and alkene copolymers. These developments require a new review of all aspects of alkene polymerization reactions with transition-metal catalysts. The first chapter in the book is an introductory text for researchers who are entering the field. It describes the basic principles of polymerization reactions with transition-metal catalysts, the types of catalysts, and commercially manufactured polyolefins. The next chapter addresses the principal issue of alkene polymerization catalysis: the existence of catalyst systems with single and multiple types of active centers. The subsequent chapters are devoted to chemistry and stereochemistry of elemental reaction steps, structures of catalyst precursors and reactions leading to the formation of active centers, kinetics of polymerization reactions, and their mechanisms. The book describes the latest commercial polymerization catalysts for the synthesis of polyethylenes and polypropylene The book provides a detailed description of the multi-center nature of commercial Ziegler-Natta catalysts. The book devotes specialized chapters to the most important aspects of transition metal polymerization catalysts: the reactions leading to the formation of active centers, the chemistry and stereochemistry of elemental polymerization steps, reaction kinetics, and the polymerization mechanism. The book contains an introductory chapter for researchers who are entering the field of polymerization catalysis. It describes the basic principles of polymerization reactions with transition-metal catalysts and the types of commercially manufactured polyolefins and copolymersThe book contains over 2000 references, the most recent up to end of 2006.

Book excerpt: Metallocene is a well known sandwich complex with two cyclopentadienyl ligands such as ferrocene. Recently, such metallocene compounds have been found to be very characteristic and they have become very important, not only in the area of organic synthesis, but also in polymerization in industry. Metal complexes with one cyclopentadienyl ligand have also become popular as half sandwich complexes. The number of researchers in the field of metallocenes has increased rapidly. However, the origin of the characteristic reactivity of metallocenes is not fully understood. In this volume, the chemistry of metal complexes with at least one cyclopentadienyl ligand is comprehensively covered by leading experts. Reactions discussed here are (i) natural product synthesis, (ii) catalytic asymmetric synthesis, (iii) cyclization reactions, (iv)catalytic reactions, (iv) polymerization reactions and (v) carbon-carbon bond cleavage reactions. The reader will have access to useful information about the current state of metallocene chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: The Organic Chemistry of Nickel, Volume I: Organonickel Complexes is devoted to a description of the organonickel complexes. The major goal is to provide a reference work, and for this reason a conventional layout has been adopted with separate chapters devoted to each type of organic ligand. In the interest of readability, known compounds have been assembled in tables at the end of each chapter, thereby allowing the text to be used for discussions of the general chemistry involved and to highlight the special reactions associated with nickel. Conscious of the needs of organometallic chemists, the authors included systems in which no nickel-carbon bond is involved. Among these is a chapter on the tetrakisligand nickel complexes and sections on dioxygen and azobenzene complexes. The nitrosyl complexes and complexes containing a metal-metal bond—topics frequently considered to be part of the domain of the organometallic chemist—have not received individual attention. Tables of the observed bond distances in organonickel complexes are provided as an Appendix; a short list of the more important review articles relevant to each organic ligand can be found at the end of each chapter.

Where earlier editions covered organic polymer chemistry, the third edition covers both physical and organic chemistry. Thus kinetics and thermodynamics of polymerization reactions are discussed. This edition is also distinct from all other polymer textbooks because of its coverage of such currently hot topics as photonic polymers, electricity conducting polymers, polymeric materials for immobilization of reagents and drug release, organic solar cells, organic light emitting diodes. This textbook contains review questions at the end of every chapter, references for further reading, and numerous examples of commercially important processes.
