Download or read book Polymer Characterization Interdisciplinary Approaches written by Clara D. Craver and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical and spectroscopic methods have been used jointly for characterization of polymers for at least four decades. Yet, new techniques permit increasingly refined determination of polymer chemistry and morphol ogy_ The correlation of this knowledge with physical properties of polymers is helpful to planned synthesis of new products. The most prominent spectroscopic techniques through the forties and fifties were infrared and ultraviolet spectroscopy. Nuclear magnetic resonance, electron spin resonance and MOssbauer spectroscopy started making sig nificant contributions to polymer chemistry in the early sixties. Still more recently fluorescence spectroscopy and laser Raman spectroscopy have become readily appli cable to polymers and are contributing significantly to the understanding of the relationship between polymer structure and properties. Determination of the distribution of monomer se quences by molecular size has become possible through combined gel permeation chromatography and spectroscopic analysis. Fragments of polymers from chemical break down or from pyrolysis are further fractionated and structurally analyzed. The relationship between the chemistry of polymers and performance can be determined from changes in chemical structure and orientation after curing, degradation, or physical or thermal manipulation of the polymers.
Download or read book Polymer Characterization by Liquid Chromatography written by G. Glöckner and published by Elsevier. This book was released on 1987-02-01 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main subject of this book is the characterization of plastics. To a high degree the properties of these polymers depend on the distribution of the molar mass and of other structural features, and small deviations frequently have a great effect. Therefore the characterization of polymers cannot be restricted to the determination of mean values but must yield information on these distributions. Using classical methods, the analytical fractionation of polymer homologues and structurally isomeric polymers is extremely time-consuming. Therefore, efficient chromatographic techniques are being increasingly employed in modern polymer characterization. In the first place, high-performance liquid chromatography is applied, in the form of size exclusion chromatography. It is also possible, however, to use other separation modes. More space is devoted to these other possibilities in this volume than is merited by their current range of applications, as the author believes that many separation problems will be solved by separation techniques of the non-exclusion type. Nevertheless, much emphasis is placed on size exclusion chromatography. Not only because of its current wide range of applications, but also because its relative importance, as a complement to other chromatographic techniques may even increase in the forthcoming years. This book is the first to cover all phenomena related to the above considerations. Starting with an introduction to basic liquid chromatography and to polymer science, it deals with the adsorption behaviour of polymers, with gradient techniques, with the kinetic band broadening in liquid chromatography, with instrumental features and packing materials. The book consists of four balanced sections and related information from about 1800 references is compiled in the tables. Some 250 figures and 30 tables will help give the reader a clear insight of the topics discussed. The book is aimed at helping the analyst or polymer chemist who is looking for information about chromatographic methods for the characterization of polymers.

Download or read book Polymer Characterisation written by B.J. Hunt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers continue to play an ever increasing role in the modern world. In fact it is quite inconceivable to most people that we could ever have existed of the increased volume and variety of materials without them. As a result currently available, and the diversity of their application, characterisation has become an essential requirement of industrial and academic laboratories in volved with polymeric materials. On the one hand requirements may come from polymer specialists involved in the design and synthesis of new materials who require a detailed understanding of the relationship between the precise molecular architecture and the properties of the polymer in order to improve its capabilities and range of applications. On the other hand, many analysts who are not polymer specialists are faced with the problems of analysing and testing a wide range of polymeric materials for quality control or material specification purposes. We hope this book will be a useful reference for all scientists and techno or industrial laboratories, logists involved with polymers, whether in academic and irrespective of their scientific discipline. We have attempted to include in one volume all of the most important techniques. Obviously it is not possible to do this in any great depth but we have encouraged the use of specific examples to illustrate the range of possibilities. In addition numerous references are given to more detailed texts on specific subjects, to direct the reader where appropriate. The book is divided into II chapters.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a series of papers originally presented at the symposium on Water Soluble Polymers: Solution Properties and Applications, sponsored by the Division of Colloids and Surface Chemistry of the American Chemical Society. The symposium took place in Las Vegas City, Nevada on 9 to 11th September, 1997 at the 214th American Chemical Society National Meeting. Recognized experts in their - spective fields were invited to speak. There was a strong attendance from academia, g- ernment, and industrial research centers. The purpose of the symposium was to present and discuss recent developments in the solution properties of water soluble polymers and their applications in aqueous systems. Water soluble polymers find applications in a number of fields of which the following may be worth mentioning: cosmetics, detergent, oral care, industrial water treatment, g- thermal, wastewater treatment, water purification and reuse, pulp and paper production, sugar refining, and many more. Moreover, water soluble polymers play vital role in the oil industry, especially in enhanced oil recovery. Water soluble polymers are also used in ag- culture and controlled release pharmaceutical applications. Therefore, a fundamental kno- edge of solution properties of these polymers is essential for most industrial scientists. An understanding of the basic phenomena involved in the application of these polymers, such as adsorption and interaction with different substrates (i. e. , tooth enamel, hair, reverse - mosis membrane, heat exchanger surfaces, etc. ) is of vital importance in developing high performance formulations for achieving optimum efficiency of the system.
