The chemistry is both wide ranging and interesting. It involves carbohydrate chemistry, the chemistry of inorganic pigments, organic resins —both natural and synthetic—and many other organic and polymeric additives. The sheet formation process also involves a considerable amount of colloid and surface chemistry. Polymer chemistry and environmental and analytical chemistry also play an important part.

The present book is a follow-up of a previous one with the title Analytical Pyrolysis of Natural Organic Polymers published by Elsevier as vol. 20 in the series Techniques and Instrumentation in Analytical Chemistry. In addition to the discussion on pyrolysis of various natural polymers, the previous book contains information on chemically modified celluloses, modified starches, etc. For this reason, the present book does not include synthetically modified natural polymers. Information on the pyrolysis process and pyrolytic techniques in general also can be found in the book on natural polymers. 

This book has two main parts, and the material is organized in chapters and sections. The first part of the book has five chapters including an introduction, a discussion on physico-chemistry of thermal degradation of synthetic polymers, a short discussion on instrumentation used in analytical pyrolysis, a chapter discussing what type of information can be obtained from analytical pyrolysis, and a chapter dedicated to the applications of analytical pyrolysis for the analysis and characterization of synthetic polymers. The chapter on applications includes only a few selected examples from the multitude existent in literature, and it is not intended to be exhaustive. Excellent monographs, such as F. W.

Polymer chemistry is an important branch of science, and polymer analysis and characterization is a common subject in scientific literature. Analytical pyrolysis is one of many tools used particularly for polymer identification and for the evaluation of polymer thermal properties. Before a more in-depth discussion on analytical pyrolysis and its application to polymer science, some basic concepts regarding the chemistry of synthetic polymers will be briefly discussed. 

The physical group undertook mainly analytical work in the field of technically interesting substances, such as catalysts, fertilisers, synthetic polymers, and metals. It set high standards and improved on the analytical methods. In 1941, Brill left LG. Farben and joined the Darmstadt Technische Hochschule as professor of inorganic and physical chemistry. ...

The principles of green chemistry are reflected in the educational courses Environment Monitoring and Protection, Chemical Engineering, Modem Chemistry and Safety, Analytical Chemistry of Environmental Objects, Physical Chemistry of Plants Polymers, Methods of Natural Chemicals Analysis, Chemistry of Wood and Synthetic Polymers, Physical-Chemical Bases of Environment Protection Processes in Pulp and Paper Industry and some others. 

NMR is now a powerful, mature analytical tool which has widespread applications in all areas of synthetic chemistry, and polymer science is no exception. High-resolution solution-state NMR is a versatile technique which not only provides accurate qualitative and quantitative information on the chemical structure of a polymeric material, but is also capable of providing detailed information on certain aspects of chain structure which is not accessible by any other technique. The purpose of this chapter is to introduce the physical basis of the NMR phenomenon, to outline the effects that determine the form of the NMR spectra of liquid-state samples, to describe the experimental techniques of solution-state NMR of polymers, and to introduce those aspects of the structure of synthetic polymers that are specially amenable to NMR analysis.

Infrared (IR) and Raman are both well established as methods of vibrational spectroscopy. Both have been used for decades as tools for the identification and characterization of polymeric materials in fact, the requirement for a method of analysis synthetic polymers was the basis for the original development of analytical infrared instrumentation during World War II. It is assumed that the reader has a general understanding of analytical chemistry, and a basic understanding of the principles of spectroscopy. A general overview of vibrational spectroscopy is provided in Sec. 5 for those unfamiliar with the infrared and Raman techniques. 

Application Reviews, published in alternating years by Analytical Chemistry, includes a section on analysis of synthetic polymers and rubbers in which ah references to specific analytical methods, including hquid chromatography, are grouped together, e.g.. Smith, P. B., et al.. Analytical Chemistry, 1997, 69, 101R-103R.
