Book excerpt: Recent development of a new generation of Ziegler-Natta Catalysts using either magnesium dichloride as carrier or methylaluminoxane as cocatalyst has markedly stimulated the research activity in the field of olefin polymerization. These discoveries have not only yielded economical processes for polyolefin production but also opened the way to a new generation of novel polymers. Moreover, the nature of active species is being clarified well by the effort to simplify catalyst systems. The present volume includes 38 papers from the 31 lectures and 18 posters presented at the symposium on `Recent Developments in Olefin Polymerization Catalysts', which covered the following topics: Overview of super-active homogeneous and heterogeneous catalysts, kinetic profile of olefin polymerization including copolymerization, characterization of catalysts and polymers, methods for the determination of active center concentration, role of Lewis bases on the catalysts isospecificity, polymerization mechanisms, and synthetic pathways for functionalized polyolefins. The contents are well balanced between fundamental research and application as well as between homogeneous and heterogeneous catalyst systems.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the proceedings of a symposium which was attended by researchers from all over the world who reported on and discussed recent advances in the field of catalytic polymerization of olefins. Over two decades have elapsed since the discovery of the Ziegler-Natta catalyst. Tremendous research effort has been aimed at improving this marvelous catalyst. In twenty-five years since the first publication, more than 15,000 papers and patents on the subject and on related subjects have appeared. This effort has yielded new generations of Ziegler-Natta catalysts with superior activity and stereospecificity. The complexities arising from the heterogeneity of the catalyst, however, have hindered understanding of the catalytic processes which take place on the catalyst surface. Nevertheless, many fundamental features of the catalyst system have now been clarified reasonably well. Recently a highly active homogeneous catalytic system has been developed, which is capable of catalyzing even isotactic polymerization of propene.

Available in PDF, EPUB and Kindle. Book excerpt: Polyolefin is a major industry that is important for our economy and impacts every aspect of our lives. The discovery of new transition metal-based catalysts is one of the driving forces for the further advancement of this field. Whereas the classical heterogeneous Ziegler-Natta catalysts and homogeneous early transition metal metallocene catalysts remain the workhorses of the polyolefin industry, in roughly the last decade, tremendous progress has been made in developing non-metallocene-based olefin polymerization catalysts. Particularly, the discovery of late transition metal-based olefin polymerization catalysts heralds a new era for this field. These late transition metal complexes not only exhibit high activities rivaling their early metal counterparts, but more importantly they offer unique properties for polymer architectural control and copolymerization with polar olefins. In this book, the most recent major breakthroughs in the development of new olefin polymerization catalysts, including early metal metallocene and non-metallocene complexes and late transition metal complexes, are discussed by leading experts. The authors highlight the most important discoveries in catalysts and their applications in designing new polyolefin-based functional materials.

Available in PDF, EPUB and Kindle. Book excerpt: Polyolefin is one of the most important materials produced in the chemical industry. The research in this area is not only scientifically challenging but also potentially economically rewarding. Many research activities, such as developing new catalysts, understanding polymerization mechanisms, modifying the products and improving the physical properties of the material, have been proceeding at a very fast pace, especially in the industrial laboratories in many countries. It is very important and exciting to bring researchers active in this area, from both the academic and industrial sectors, to communicate their new findings. To the best of my knowledge, a symposium covering diverse aspects of polyolefin research has not been held in the USA for many years. With this in mind, a symposium entitled "Recent Advances in Polyolefins" was held at the National ACS Meeting in Washington D. C. , August 23-28, 1992. This symposium covered both scientific and technological aspects of polyolefin, which included four sections: CatalystIPolymerization, Functionalization of Polyolefins, Blends of Polyolefins with Other Polymers, and Applications. More than 50 papers, including 20 foreign contributions, were presented during three and a half days of meetings. It was truly exciting to see key researchers from both academic and industrial laboratories exchange their recent results and to share the important developments in polyolefins. This volume is based on the same spirit and is intended to capture some of the most recent and emerging technical achievements presented at the meeting.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the most important topics concerning cationic Ziegler-Natta and ring-opening metathesis polymerization of cycloolefins. The work describes the major pathways that cycloolefins can follow under the action of specific catalytic systems, essentially vinyl and ring-opening polymerization, both reaction types allowing the manufacture of distinct products with wide applicability in modern technologies. The comprehensive data available on this subject are logically and systematically selected and reviewed throughout 18 chapters, according to the basic catalytic processes involved, types of monomers and catalysts employed, reaction conditions and application fields. The modern trends in design of chiral metallocene catalysts, well-defined living metathesis catalysts, catalysts tolerant toward functionalities and water systems are highlighted. The book discusses in detail the relevant aspects of these processes including reaction thermodynamics, kinetics, mechanisms and stereochemistry and correlates the structure of produced polymers with their chemical and physical-mechanical properties. Related important topics include Ziegler-Natta polymerization of olefins and dienes, atom transfer radical polymerization of vinyl compounds, metathesis of olefins and acetylenes, acyclic diene metathesis reaction, carbonyl olefination reaction, metathesis polymerization of acetylenes, metathesis degradation of polymers and ring-opening polymerization of heterocycles. Special emphasis is laid upon the manufacture of commerical products, new polymers and copolymers of potential interest for industry and design and synthesis of speciality polymers with particular structures and architectures and desired properties. The book critically evaluates the most recent achievements reported in this field and outlines the modern trends on the research and application of the catalytic processes for cycloolefin polymerization. For the first time, comprehensive information about the published data on the subject up to now is provided for both academic and industrial researchers working in the areas of polymer chemistry, organic and organometallic chemistry, surface science and catalysis, petrochemistry and chemical engineering. This stimulating book offers an enlightening introduction and a quick documentation on the subject as well as a solid background in this field. Moreover, the work offers a wealth of useful information for specialists applying polymers in various scientific and industrial areas.

Available in PDF, EPUB and Kindle. Book excerpt: Polyolefins comprise the majority of the world's plastics consumption. Polyethylene and polypropylene are the two most widely utilized materials due to their exceptional properties and their inexpensive monomer feedstock. However, the polymers' true success derives from the heterogeneous catalysts that produce them. The discovery of these catalysts by Ziegler and Natta in the mid 20th century allowed for the linearity of polyethylene and the regio- and stereoregularity of polypropylene to be inherent in the microstructures. Additionally, the catalysts' simplicity and effectiveness are what make them the primary method for the commercial synthesis of polyolefins. The homogenous analogues of the Ziegler-Natta catalysts have given researchers the opportunity to tailor the properties of the polyolefins even further. Early group metal catalysts have been prominently studied due to their similarity to the heterogeneous systems. However, the arrival of late-transition metal catalysis for olefin polymerization delivered the ability to control microstructures in new ways as well as tolerate functionality. This work describes the investigations into the development of new nickel-mediated processes for the polymerization of olefins. Nickel (II)!-diimine catalysts have been previously developed for the regioregular "-2 enchainment of!-olefins. However, controlling the tacticity has proven to be quite difficult. Chapter two describes work toward further controlling the stereoselectivity of these catalysts to produce "-2 enchain poly(!-olefins) with high isotacticity, and in the case of 1-butene, a new class of semi-crystalline polyolefins. Ligand sterics and electronics aid in the elucidating mechanistic insight into this unique polymerization. Chapter three regards the development of an open geometry neutral nickel catalyst exhibiting high activity in ethylene polymerizations. The presence of bulky substituents on an amidinate ligand protects the axial sites of an active square-planar nickel center from associative displacement of a growing polymer chain, producing higher molecular weight polymer with greater activities than previously reported catalysts of this type. The addition of copper (II) bromide further enhances the activity of the catalyst by producing higher turnovers and achieving a much more narrow molecular weight distribution. Possible explanations for the copper's effect are discussed.

Book excerpt: With an enormous velocity, olefin polymerization has expanded to one of the most significant fields in polymers since the first industrial use about 50 years ago. In 2005, 100 million tons of polyolefins were produced - the biggest part was catalyzed by metallorganic compounds. The Hamburg Macromolecular Symposium 2005 with the title "Olefin Polymerization" involved topics such as new catalysts and cocatalysts, kinetics, mechanism and polymer reaction engineering, synthesis of special polymers, and characterization of polyolefins. The conference combined scientists from different disciplines to discuss latest research results of polymers and to offer each other the possibility of cooperation. This is reflected in this volume, which contains invited lectures and selected posters presented at the symposium.
