Spectroscopy of Polymers. By J. L. Koenig. American Chemical Society, Washington DC, 1992. XVI, 328 pp., paperback $49.95.-ISBN 0-8412-1924-9
To characterize the structures of synthetic polymers one
needs to determine various properties that are specific to
polymers, such as the molar mass, tacticity, configuration
and conformation, copolymerization statistics, etc. To these
must be added the organization and dynamic behavior of the
molecular chains in the solid state, or in the different forms
of liquid crystalline polymers. Spectroscopic methods are
becoming increasingly important as ways of investigating
these properties. During the last decade there have been especially rapid developments in the areas of vibrational spectroscopy (Fourier transform infrared (FTIR) and Raman
spectroscopy) and NMR spectroscopy, and these advances
are described in the book by J. L. Koenig reviewed here.
However, the title is somewhat misleading, since in addition
to these two areas there are many other spectroscopic methods that are successfully applied to polymer studies. The
book is based on the author’s many years of experience in
research and teaching in the two fields described, and it
replaces his earlier book on the same subject. It is intended
for graduate students and polymer scientists who are not
experts in these areas of spectroscopy. Its purpose is to enable them to choose the most suitable methods to solve
specific polymer problems, and to equip them with enough
basic knowledge to make intelligent use of more advanced
monographs and of the original literature.

This approach is an extremely useful one for practical
laboratory work, and Koenig fulfills the task outstandingly
well. In addition to clearly explaining the standard methods
used, for example, to determine the microstructure of polymers in solution, he describes more recent developments
such as attenuated total reflection (ATR) Raman spectroscopy and FT-Raman spectroscopy. Even some techniques that are complicated to explain, such as two-dimensional (2D) FTIR spectroscopy, are treated in a concise and
understandable way. In the case of NMR spectroscopy a
considerable amount of space is devoted to structural characterization, and especially to the dynamics of polymers in
the solid state. The discussion makes it clear that the current
state of the art in the NMR spectroscopy of solid polymers
allows not only the determination of chemical structure using the CP-MAS (cross-polarization magic angle spinning)
technique but also the measurement of various relaxation
parameters. Last but not least, Koenig devotes a chapter to
NMR imaging techniques and shows the potential of these
methods for the characterization of elastomers and for
studying diffusion processes, mainly using examples from his
own work.
For each of the techniques covered Koenig begins with the
basic physical principles, deliberately keeping the number of
mathematical formulas to a minimum. This is followed by a
discussion of the experimental details that are important in
practice, then the applications of the method are illustrated
by numerous examples from different areas of polymer research. The advantages and disadvantages of each method
are clearly set out; here the author is not afraid to state his
personal views which sometimes conflict with those expressed in the literature.
The book makes easy reading, thanks to the many useful
illustrations and the excellently written text, and can be recommended for all graduate students and polymer scientists.
It should find a place in the library of every laboratory concerned with the physics or chemistry of macromolecules,
which expressly includes industrial laboratories.
