Available in PDF, EPUB and Kindle. Book excerpt: During the thermal polymerization of monomers such as methyl methacrylate (MMA) or styrene, we have been able to investigate both the static and the dynamic properties of the polymer formed, i.e., polymethyl methacrylate (PMMA) or polystyrene, in terms of the molecular weight, the second virial coefficient, the radius of gyration, the translational diffusion coefficient and its corresponding equivalent hydrodynamic radius as well as estimated of the size (or molecular weight) distribution of the polymer in dilute solution; and in terms of the isothermal compressibility, the cooperative diffusion coefficient and a slow characteristic decay time which has sometimes been related to the self-diffusion coefficient in the semidilute solution regime. By combining a spectroscopic technique, such as Raman scattering, which can determine the polymer concentration non-evasively during the polymerization process, with laser light scattering, we have demonstrated a viable procedure for on-line monitoring of solution polymerization processes permitting us to investigate detailed macromolecular properties in solution polymerization kinetics. The same approach has been extended to examine the thermal polymerization of melt hexachlorocyclotriphosphazine and of hexachlorocyclotriphosphazene in 1,2,4-trichlorobenzene to form poly(dichlorophosphazene).

Book excerpt: This revised and updated Second Edition of the best-selling reference/text is essential reading for students and scientists who seek a thorough and practical introduction to the field of polymer spectroscopy. Eleven chapters cover the fundamental aspects and experimental applications of the primary spectroscopic methods. The advantages and disadvantages of the various techniques for particular polymer systems are also discussed. The goal of the author is not to make the reader an expert in the field, but rather to provide enough information about the different spectroscopic methods that the reader can determine how the available techniques can be used to solve a particular polymer problem. This Second Edition contains new and updated information on techniques in IR and NMR, as well as an all-new chapter on Mass Spectrometry.
Book Synopsis Developments in Polymer Characterisation—4 by : J.V. Dawkins
Download or read book Developments in Polymer Characterisation—4 written by J.V. Dawkins and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume includes reviews on tackling polymer characterisation problems and on developing specific characterisation techniques. The first two chapters and the last chapter describe progress in providing character isation information for polymers containing long-chain branching, for polymer blends, and for polymers having preferred orientation. The remaining chapters review progress in individual techniques, showing with examples the characterisation results which may be obtained. It is recognised that the degree of chain branching which can evolve in some polymerisation processes can have a marked effect on the flow properties of a polymer, and therefore on polymer processing behaviour. In the first chapter the characterisation of long-chain branching from measurements of the molecular size and molar mass of a polymer in dilute solution is outlined. It is indicated that a complete characterisation of branching requires the combined use of several techniques, emphasising in particular recent developments involving gel permeation chromatography. Thermal analysis and infrared spectroscopy are widely used techniques in polymer characterisation. Both techniques can provide, very quickly, significant results with readily available instrumentation. This is illustrated by the review of the characterisation of polymer blends by thermal analysis in Chapter 2. An assessment of blend morphology, which influences the behaviour of a material consisting of two or more polymers, is presented in terms of transition temperatures. Conventional infrared spectroscopy involves dispersive spectrometers which do not always provide accurate information on composition and structure for complex polymeric materials.
Book Synopsis Introduction to Polymer Spectroscopy by : W. Klöpffer
Download or read book Introduction to Polymer Spectroscopy written by W. Klöpffer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has grown out of several courses oflectures held at the University of Mainz in the years 1978 to 1981, at the Ecole Poly technique Federal, Lausanne, and at the University of Fribourg, Switzerland. The last two courses were held in the framework of the "3e Cycle" lectures in June 1981. According to this genesis, the emphasis of the book lies on a unified and concise approach to introducing polymer spectroscopy rather than on completeness which, by the way, could hardly be achieved in a single volume. In contrast to other books on this subject, equal weight is given to electronic spectroscopy, vibrational spectroscopy and spin resonance techniques. The electronic properties of polymers have been increasingly investigated in the last ten years; until recently, however, these studies and the spectroscopic methods applied have not generally been considered as part of polymer spectroscopy. The increasing use of electronic spectroscopy by polymer researchers, on the other hand, shows that this type of spectroscopy provides efficient tools for gaining insight into the properties of polymers which cannot be obtained by any other means.

Download or read book Classical Light Scattering from Polymer Solutions written by Pavel Kratochvíl and published by Elsevier Publishing Company. This book was released on 1987 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical light scattering from dilute polymer solutions is one of the few absolute, rigorously founded methods for the determination of molar mass and molecular size of macromolecular substances, and for the quantitative characterization of solute-solvent interaction. Light scattering is thus one of the most fundamental methods of the physical chemistry of polymers, and the present book provides an introduction to this technique. elements of practice and application of light scattering. Although there are a number of advanced monographs and reviews currently available on light scattering from polymer solutions, the appearance of this book marks the first introductory text of its kind. Polymer chemists wishing to make a start in light scattering will find this book an indispensable aid in their work.
