Nucleinsiiuren (Nucleic acids). By D. Beyersmann. Chemische Taschenbucher Band 16 (Chemical Pocketbooks Vol.
16). Verlag Chemie GmbH, Weinheim/Bergstr. 1971. 1st
edit., viii, 192 pp., numerous figs, and tables, bound,
book. It is a pity that the book contains no contributions
on high-temperature plastics, such as diphenyl oxides,
polyimides, and poly-p-xylylenes, though sufficient literature for such contributions has existed for a number of
years. The polysulfones should also belong to this volume.
This book is the latest in the “Chemical Pocketbooks”
series, which have already won a name for themselves by
their good presentations of interesting specialist topics; it
deals with the topical subject of nucleic acids in six chapters.
Nevertheless, the book provides users and processors with
a good, concise source of quickly retrievable information
on polyacetals, epoxy resins, etc. Since the relevant literature is abundantly cited, chemists and applications technologists who wish to delve deeper into the subject can do so
with the aid of this book. The volume can be wholeheartedly
recommended to all who wish to obtain fairly detailed
information on the plastics mentioned in the title.
A discussion on nomenclature, the fundamental monomer
building blocks, and .the chemistry of the high-molecular
nucleic acids is followed by a detailed exposition on the
molecular weight and conformation of these compounds.
The remaining four chapters include the essential facts on
the biosynthesis of nucleotides and a comprehensive treatment of the metabolism of nucleic acids, tables helping to
present the wealth of information in a clear and easily
comprehensible manner. After the role of nucleic acids in
the transmission of genetic information has been clearly
shown and a number of regulation mechanisms have been
discussed, the last chapter indicates some possible ways of
attacking the problems of the metabolism and function of
the nucleic acids.
The author has succeeded in presenting the most important
aspects of this very extensive field in a clear, detailed, and
attractive manner. The reader is familiarized with the
current position on the chemical and biochemical viewpoints on the nucleic acids, and can go into the subject
more deeply by means of the literature references (there
could have been more of these in one or two chapters). The
book is recommended to anyone requiring information on
nucleic acids.

Kunststoff-Handbuch (Plastics Handbook). Vol. 11. Polyacetals, Epoxy Resins, Polymers Containing Fluorine,
Silicones, etc., Production, Properties, Processing, and
Use. Edited by R. Vieweg, M . Reiher and H . Scheurlen.
Carl Hanser Verlag, Munchen, 1971, 1st ed., xxii, 616 pp.,
362 figures, 176 tables, bound DM 220.-.
Volume 11, the latest volume of the collective work“], deals
with plastics that do not fit into the rigorous classification
of the earlier volumes. The polyacetals, epoxy resins,
polymers containing fluorine, and silicones are discussed
in detail, while polyvinylalcohols, polyvinylacetals, polyvinyl ethers, polyvinylpyrrolidone, and poly-N-vinylcarbazole are described relatively briefly. The first group of
products mentioned above, like the major plastics described in earlier volumes (polyethylene,polyvinyl chloride, polystyrene, etc.),are discussed in sections dealing with production, properties, processing, and use, after an introduction
presenting a historical survey and some economic data.

0 . - A . Neumiiller. Franck’sche Verlagshandlung, W. Keller & Co., Stuttgart, 1972, 7th ed., vol. 1; xiv, 734 pp.,
numerous figs., bound, DM 1lo.--.
Twenty-five years have elapsed since the first edition of this
work appeared. The first volume of the seventh edition is
now out, covering the entries from A to C. The new editor
is 0 . - A . Neumiiller, who took over when E. Uhlein died.
On thumbing through the new first volume, one first notices
that it is now the pages and not the columns that are
numbered, the head words stand out, and the material
must have been subjected to very careful editing and
proofreading. The number of entries has not yet been
specified, but comparison with the sixth edition‘’] points
to a roughly 10% increase in volume. Almost all the
entries have been revised or rewritten; in particular those
coming under organic chemistry, physical chemistry, biochemistry, and nuclear chemistry have been extended. This
amplification has not been entirely successful in the case
of named reactions, because some of them are still missing.
The key words are also given in English and French, and, as
mentioned in the Preface, they will be listed alphabetically‘
at the end of the last volume. However, this list is likely to
be incomplete, because the terms are not always given after
the head words. Compounds are named according to
IUPAC rules. One or more sources of supply are usually
specified for each substance, which will certainly be found
most useful. The literature references have been increased
in number and are now fully up to date. The listing of
tradenames in entries on drugs has been mostly abandoned.
This volume deserves a good reception, as do the further
volumes of Rompps Chemie Lexikon, which are to be
published at intervals of six months.

The sections on epoxy resins and polymers containing
fluorine are particularly successful. A rather more comprehensive discussion would have been justified in the
chapter on polyvinyl acetals, polyvinyl ethers, etc. Lacquer
raw materials should also find a place in a plastics hand-
