There is a large and increasing variety of polymers currently in use both for domestic and industrial applications. The properties of polymers are deter mined not only by their chemical type, but also by their molecular mass and molecular mass distributions. However, while the chemical type of polymers can be determined relatively easily, the average molecular masses and molecular mass distributions are more difficult to measure. The molecular mass averages of a polymer are measured by specialized and complex techniques such as light scattering (for weight average) and osmometry (for number average). Thus, complete characterization of the molecular mass distribution of a polymer by such means requires separating the sample into many fractions which can then be examined individually. Since size exclusion chromatography was introduced as a rapid and straightforward technique for the characterization of polymer molecular mass distributions, there have been tremendous increases in development and applications, and it was felt appropriate to bring together into a single volume the information required by scientists from many disciplines who wish to use the technique. This book should be useful to existing users, those who are new to the technique, and those who may be familiar with the basic technique and now wish to extend their capabilities to more complex applications (or to consider the potential of a number of related techniques). The book will also be of general interest to the experienced liquid chromatographer.

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.

Size-exclusion chromatography (SEC) is used for the characterization and/or separation of macromolecules. Size-based sampling of column pore volume provides information in terms of the molar mass averages and distributions of disperse polymers. The history of the development, the basic theory of column separations, calibration, and detection strategies for obtaining absolute molar mass information are described, as are modern multidetector techniques and the incorporation of SEC into two-dimensional liquid chromatographic arrangements.

Although size exclusion chromatography (SEC) is perhaps the most popular and widely used technique for determining the molecular weight distribution of polymeric materials, there have been very few texts written on this topic. During the past decade, SEC has experienced a considerable amount of growth in regard to column and detector technology and new applications. With these advances, SEC can now be used for determining absolute molecular weight, polymer chain conformation and size, and branching, as well as polymer solution properties. This book introduces the reader to the fundamentals of SEC with emphasis on practical aspects of the technique, such as column and mobile selection, calibration, new detector capabilities and guidelines for performing SEC on most types of polymers, especially those of industrial importance. This book is intended for either those new to the field of SEC, or for those research workers who require a more comprehensive background.

A comprehensive, practical approach to three powerful methods of polymer analysis and characterization This book serves as a complete compendium of three important methods widely used for the characterization of synthetic and natural polymers—light scattering, size exclusion chromatography (SEC), and asymmetric flow field flow fractionation (A4F). Featuring numerous up-to-date examples of experimental results obtained by light scattering, SEC, and A4F measurements, Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation takes an all-in-one approach to deliver a complete and thorough explanation of the principles, theories, and instrumentation needed to characterize polymers from the viewpoint of their molar mass distribution, size, branching, and aggregation. This comprehensive resource: Is the only book gathering light scattering, size exclusion chromatography, and asymmetric flow field flow fractionation into a single text Systematically compares results of size exclusion chromatography with results of asymmetric flow field flow fractionation, and how these two methods complement each other Provides in-depth guidelines for reproducible and correct determination of molar mass and molecular size of polymers using SEC or A4F coupled with a multi-angle light scattering detector Offers a detailed overview of the methodology, detection, and characterization of polymer branching Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation should be of great interest to all those engaged in the polymer analysis and characterization in industrial and university research, as well as in manufacturing quality control laboratories. Both beginners and experienced can confidently rely on this volume to confirm their own understanding or to help interpret their results.
