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. There is no doubt that this finding will not only contribute to our understanding of the detailed mechanism of polymerization but also stimulate the development of various kinds of tailored polymers. Thus this subject will remain of paramount importance in the development of chemistry and polymer science for a long time to come.

Available in PDF, EPUB and Kindle. Book excerpt: The discoveries of organometallic catalysts for olefin polymerization by Karl Ziegler and that of stereoregular olefin polymers by Giulio Natta are probably the two most important achievements in the areas of catalysis and polymer chemistry in the second half of this century. They led to the development of a new branch of chemical industry, and to a large volume production of high-density and linear low-density polyethylene, isotactic polypropylene, ethylene-propylene rubbers, isotactic poly I-butene, and poly-4-methyl-l-pentene. These discoveries merited the Nobel prize, which was awarded to K. Ziegler and G. Natta in 1963. The initial works of Ziegler and Natta were followed by an "explosion" of scientific papers and patents covering all aspects of polymerization chemistry, catalyst synthesis, and polymerization kinetics as well as the structural, chemical, physical, and technological characteristics of stereo regular polyolefins, polydienes, and olefin copolymers. It is sufficient to say that in the twenty-five years after the first publications more than 15,000 papers and patents appeared on subjects related to the area. . The development brought about the establishment of several prominent groups of scientists occupied with the study of olefin polymerization. The most important of these were scientific schools in Italy, Germany, England, the United States, Japan, the Soviet Union, Czechoslovakia, and Venezuela. In addition, many major chemical and petrochemical corporations throughout the world established labora tories devoted to the development of the technology of catalyst synthesis and olefin polymerization.

This book was released on 2013 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the evolution of Ziegler-Natta olefin polymerization catalysts, considerable efforts have been made to characterize the surface chemistry, structural and morphological aspects of the support/catalyst which are known to greatly affect the performance and catalyst activity. The theme of this monograph is to introduce and develop an active and realistic model for supported Ziegler-Natta polymerization catalyst. This model offers unique possibilities for characterization of the surface chemistry and morphology of both support and catalyst by surface science and microscopic techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Forty years after Ziegler's discovery of the "Aufbaureaktion" and low-pressure ethene polymerization, transition metal catalyzed olefin and diolefin polymerization continues to represent one of the most active and exciting areas. Since the 1980s, outstanding scientific innovations and process improvements have revolutionized polyolefin technology and greatly simplified polymerization processes. Well-defined catalyst systems are now at hand and facilitate the understanding of basic reaction mechanisms and correlations between catalyst structures, polymer microstructures, and polymer properties. This book reviews some of the modern approaches in organometallic chemistry, Ziegler-Natta catalysis, polymerization processes, design of novel materials, and the modelling in catalyst and process development.

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.
