Advances in Structure Research by Diffraction Methods V01.3.
- Fortschritte der Strukturforschung mit Beugungsmethoden,
Bd. 3. Edited by R . BriII and R . Mason. Friedr. Vieweg u.
Sohn, Braunschweig 1970. 1st Edit., iii, 251 pp., 77 figures,
linen D M 48.-.
Like the first two volumeslll, the present third volume again
contains contributions by well-known authors. The four
articles are written in English by French, German, and Russian authors.
A . Authier presents a 50-page treatment of “Ewald Waves in
Theory and Experiment (Dynamical Theory of X-Ray Diffraction)”. The counterpart of this in some sense is a n article
(48 pp) on “Dynamical Theory of Electron Diffraction” by
K . Kambe and K . MoliBre.
R. Husemann, A . Schonfeld, and W. WiIke write in 72 pages
o n “Small Angle Scattering”. The particularly extensive
bibliography here follows on that given by Yudowitch in the
book by Guinier and Fourner on the same subject, and covers
the period from 1955 t o 1967 “as fully as possible” with 530
references.
The fourth and last contribution (75 pp.) is a n article by
A . I . Kitajgorodskij entitled “General View o n Molecular
Packing”.
The articles are aimed at readers who have had contact in
their work with the material in question. They should be of
great value t o such readers. On the other hand, they are
probably too difficult for the interested non-specialist, for
whom they are not really intended in any case.

Kunststoff-Handbuch. Aufbau, Verarbeitung, Eigenschaften
und Anwendung der synthetischen Werkstoffe. Bd. V:
Polystyrol. (Plastics Handbook. Structure, Processing,
Properties, and Uses of Synthetic Materials. Vol. V. Polystyrene). Edited by R . Vieweg and G . Daumiller. Carl Hanser Verlag, Miinchen 1969. 1st Edit., xxi, 876pp., 675
figures, 126 tables, linen D M 234.-.
The present volume121 on polystyrene, which occupies the
third place in economic importance among plastics, is particularly successful, since the contributions on its production,
processing, properties, and uses are well matched both in size
and in content. So much is known about this plastic that the
collation of the various contributions from outstanding specialists into a coherent chapter is in itself a creative process,
in which the editors have been very successful. The arrangement of the materialissystematic and clear; the references and
the subject index make it easy t o find one’s way around, and
the text is well supported by tables and by good illustrations.
An introduction describing the history and the economic importance of polystyrene is followed by sections on its polymerization and processing, in which considerable space is
devoted t o rheology. In addition t o injection molding, extrusion, deep drawing, compression molding, and sintering,
further processing, such as the joining of polystyrene moldings by cementing and welding, a s well a s metalizing and
printing (in an appendix), is also described. The section o n
properties, in which copolymers and high-impact modified
polystyrenes are also discussed, covers the mechanical, thermal, electrical, and aging behavior of this group of plastics.
Two outstanding and excellently illustrated sections are
devoted t o the use of polystyrene and polystyrene foams.
The authors of the various chapters, who are carefully selected experts in their fields, have brought together a wealth
of experience that provides the user of the volume with a coherent, valuable, and rapid source of information.
The volume can be warmly recommended t o processors, engineers, chemists, physicists, and students who wish information o n special problems in connection with polystyrene.

The Chemistry of Fluorine and its Compounds. By H . J .
Emele‘us, Academic Press, New York-London 1969. 1st
Edit., ix, 133 pp., numerous formulas, bound 6f s.
This monograph is not intended t o present every individual
item of knowledge about fluorine and its compounds. The
author’s intention is merely t o provide a brief survey of the
very extensive chemistry of fluorine. Instead of trying t o
present exhaustive information, he tries above all to demonstrate the shortage of physical data and to point out unsolved
problems of fluorine chemistry in order to attract young
scientists to this field.
The fluorine chemistry of the elements of the main groups
of the periodic table is discussed chapter by chapter in a very
informative manner, and great attention is given t o unsolved
problems. Short, clear summaries of the chemistry of hypofluorites, perfluoro organometallic compounds, perfluoro
aromatic compounds, and fluoroalkyl and fluoroaryl derivatives of the transition metals form a logical supplement. A
brief introduction is devoted t o the properties of fluorine and
deals with all the peculiarities that give fluorine a special
place among the halogens and make it so interesting to chemists in all fields.
The presentation and print are very pleasing, and the book is
written in a flowing and lucid manner and is free from printing errors. The arrangement and the choice of material show
that the author, who has greatly enriched the chemistry of
fluorine and paved the way for new developments over the
past 30 years by his own scientific work, has a complete picture of the subject matter. The book can be wholeheartedly
recommended t o all chemists, and particularly t o all undergraduates, graduate students, and chemistry lecturers.

Reagents for Organic Synthesis. Vol. 2. By Mary Fieser and
L. F. Fieser. Wiley-Interscience, New York-London-Sydney-Toronto 1969. 1st Edit., 538 pp., bound D M 72.-.
The first volume of this handbook[ll has proved a n indispensable aid in the reviewer’s laboratory. I t is now undoubtedly one of the standard works for the organic chemistry
laboratory. The present second volume covers the literature
of the next 21/2 years u p t o January 1969. It contains 1320
further references o n 320 reagents that were discussed in the
first volume, as well a s 550 references o n 226 reagents that
are mentioned in the book for the first time. The alphabetic
arrangement and the well-proven plan of the text on the
individual reagents have been retained. This second part is
again liberally provided with structural formulas to explain
the examples of applications, and this makes for greater ease
of scanning.
Special attention is paid in this volume to the organometallic
reagents, as befits their steadily growing importance. European companies are now also listed among the suppliers. The
positive impression of the first volume can also be claimed
unreservedly for the second. If any criticism is necessary, it
relates only to the organization of the book and not to its
content.
I n our opinion, the decision to update the handbook by supplementary volumes, though convenient, is rather shortsighted. If a supplementary volume of about 500pages is
required t o cover the literature of only 21/2 years, it can be
seen that this work will lose the character of a laboratory
handbook in a short time. Moreover, the ease of scanning
will certainly not be helped by the addition of a large number
of supplementary volumes.
We feel that it would have been much better t o revise and
expand the main volume at short intervals. This would preserve its character as a laboratory handbook, and would also
have the advantage that the authors would constantly be
forced t o deal with the reagents and examples in accordance
