Download or read book Polyelectrolytes written by E. Sélégny and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a number of articles inspired by the NATO Advanced Study Institute on 'Charged and Reactive Polymers l' held in France in June 1972. This general title indicates simply the intention of a series. The meeting dealt mainly with the fundamental problems of the physical chemistry of polyelectrolytes in solution. Some of the articles reproduce the lectures exactly as they were delivered. Some others have been modified to a greater or lesser extent, and this as a result of improvements or new inspiration arising from comments and discussions. In previous larger conferences on macromolecules, polyelectrolytes constituted only a marginal problem and few were the individual communications or short was the time al10tted to this subject. In other meetings of a biophysical character the uses of the techniques of charged macromolecules have been exposed with less attention given to the theories or to the creation or interpretation of these techniques. AU of us felt that the time had come to enumerate and to evaluate this increasing science of polyelectrolytes which has become of major interest. During the whole period of the Institute physical chemists discussed their mutual problems for more than a week, and of ten far into the night! One of the advantages of such an Institute is to enable the Directors and the mem bers of the Scientific Committee to establish a logical order in the lectures; this order has been respected in the present edition.

Download or read book Organometallic Catalysts and Olefin Polymerization written by R. Blom and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Catalysis is more art than science", probably all of you have heard and even used this expression. Whether it is true or not, it alludes to the experience that new catalysts are hard to find, and near impossible to predict. Hard work and a lifetime of experience is invaluable. However, a keen mind might give insight into where to search, but not necessarily about where to find the answers. Historically, "quantum leaps" have often arisen from serendipity - we all know the story about the nickel-contaminated reactor that triggered further research towards the first coordination catalyst for ethene polymerization. Taking advan tage of this event, Karl Ziegler became the first chemist to earn both a Nobel prize and a fortune for the same invention. A broken NMR tube helped Walter Kaminsky discover the effect of high concentrations of methylaluminoxanes as co catalysts for metallocenes. When air reacted with the concentrated trim ethyl aluminum solution, sufficient amounts of methylaluminoxanes were formed, and the lazy catalyst dormant in the NMR tube suddenly became sensationally active. Ziegler and Kaminsky were lucky and had the genius needed to take advantage of their luck.

Available in PDF, EPUB and Kindle. Book excerpt: The International Winter School on Electronic Properties of Polymers Orien tation and Dimensionality of Conjugated Systems, held March 9-16, 1991, in Kirchberg, ('lYrol) Austria, was a sequel to three meetings on similar subjects held there. The 1991 winter school was again organized in cooperation with the "Bundesministerium fUr Wissenschaft und Forschung" in Austria, and with the "Bundesministerium fUr Forschung und Technologie" in the Federal Republic of Germany. The basic idea of the meeting was to provide an opportunity for experienced scientists from universities and industry to discuss their most re cent results and for students and young scientists to become familiar with the present status of research and applications in the field. Like the previous winter schools on polymers, this one concentrated on the electronic structure and potential~ for application of polymers with conjugated double bonds. This time, however, special attention was paid to the effects of orientation and dimensionality. Anisotropy of the electric conductivity in stretch-oriented samples and whether the transport mechanisms are one-, two-, or three-dimensional or might even have a "fractal dimensionality" were there fore central topics. The problem of orientation was extended to systems such as Langmuir-Blodgett films and other layered structures. Accordingly, thin films were the focus of most of the application oriented contributions. Whereas in the previous winter schools discussions on applications dealt with "large volume applications" such as electromagnetic shielding and energy storage, this time "molecular materials for electronics" and prospects of "molecular electronics" were at the center of interest.

Book excerpt: In the past ten years the science of Polyconjugated Organic Materials has grown rapidly and is now experiencing the uncorrelated explosive development typical of a new science. The transfer of the basic scientific knowledge of these materials to the field of technology and industry is presently the focus of interest in academic and industrial circles. New devices are being developed which are paving the way for future technologies. Organic materials have become the focus of attention in these technologies. The large and very fast nonlinear optical response of organic molecules has generated new theoretical and experimental physics as well as new synthetic chemistry. The advancement of knowledge and the new achievements in this field require the interdisciplinary practice of chemists, physicists and engineers who can talk the same technical language on molecular systems which show specific physical properties. The purpose of this book is to introduce beginners to the field of nonlinear optics in organic materials and to expose specialists in one field to the problems of the other fields. Since organic molecules with a large and very fast nonlinear optical response are being continuously discovered the contributions focus on this class of materials. The volume provides a useful introduction for all those interested in the theoretical and experimental aspects of this expanding field.

Download or read book Coordination polymerization written by James C.W. Chien and published by Elsevier. This book was released on 2012-12-02 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coordination Polymerization contains the proceedings of a symposium sponsored by the American Chemical Society and held at the University of California-Los Angeles on April 3, 1974. The papers explore developments in coordination polymerization and cover topics ranging from stereoselection and stereoelection in a-olefin polymerization to heterogeneous Ziegler-Natta polymerization; transition metal alkyl polymerization catalysts; chain transfer in Ziegler-type polymerization of ethylene; and stereospecific polymerization of diolefins by h3-allylic coordination complexes. This book is comprised of 13 chapters and begins with a discussion on Karl Ziegler's major contributions to the chemistry of free radicals, organo-alkali metal compounds, many-membered rings, and organotransition metallic compounds. The next two chapters focus on the origin of steric control in the polymerization of a-olefins, with emphasis on steroselection and stereoelection as well as the influence of the chirality of the transition metal on the stereoregularity of the resulting polymer. The problem of counting active sites is then addressed, and results obtained with various methods are compared. The mechanisms of initiation, propagation, termination, and transfers in polymerizations by (p-C5H5)2 TiCl2 catalysts are also considered, along with polymerizations by allyl, benzyl, trimethylsilmethyl, and other derivatives of Ti and Zr. The last three chapters examine the kinetics of Ziegler-Natta polymerization; the Langmuir adsorption mechanism; supported Ziegler-Natta catalysts; factors that affect the stereoregularity of polymerization of propylene by supported catalysts; and polymerizations of diolefins to equibinary polymers by h3-allylic coordination complexes. This monograph will be of interest to chemists as well as polymer scientists and engineers.

Download or read book Metalorganic Catalysts for Synthesis and Polymerization written by Walter Kaminsky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: 45 years after the discovery of transition metals and organometallics as cocatalysts for the polymerization of olefins and for organic synthesis, these compounds have not lost their fascination. The birthday of Karl Ziegler, the great pioneer in this metalorganic catalysis, is now 100 years ago. Polyolefins and polydienes produced by Ziegler-Natta catalysis are the most important plastics and elastomers. New impulses for the polymerization of olefins have been brought about by highly active metallocenes and other single site catalysts. Just by changing the ligands of the organometallic compounds, the structure of the polymers produced can be tailored in a wide manner. In invited lectures and posters, relevant aspects of the metalorganic catalysts for synthesis and polymerization are discussed in this book. This includes mechanism and kinetics, stereochemistry, material properties, and industrial applications.
