Polyamidhides with elastic properties, suitable as foils, fibers,
and varnishes, are prepared by polycondensation of diamides
Low-molecular polymers containing terminal hydroxy groups,
suitable for the preparation of polyurethanes, are obtained
by the polymerization of conjugated dienes with hydrogen
peroxide as catalyst in a liquid multiphase reaction system.
The preferred reaction medium is a mixture of isopropanol
and water containing 70-88‘x of the alcohol. [DOS 2326677;

long-expected supplement to the first volume[*] which dealt

with the identification of high polymers and resins and has
meanwhile proved its value.
The present volume begins with an outline of the most important experimental analyticai methods, which could be kept
quite short in view of the explanations in the first volume;
finding the experimental details for a given case is made
easier by the large number of references to the extensive
literature. Then follows a description of the methods of detection of additives and processing aids: solvents, softeners, antiaging materials, stabilizers, vulcanization agents, fillers, pigments, antioxidants, antistatics, biocides, and flame-retardants
are considered.

The following spectral section forms the largest part of the
book. In some 1100 IR and 50 UV spectra the user has at his
disposal an invaluable store of comparative material on the
above-mentioned auxiliary additives. The excellent graphical
presentation, linear in wave number, permits unambiguous
comparison with his own spectra.
It should also be mentioned that, besides the extensive spectral
section, there are abundant data on thin-layer chromatography, gas chromatography, and mass spectrography, as well
as information about solvents and an extensive bibliography.
This second volume of the Atlas is an aid for the analytically
active polymer chemist and, after short use, will become indis-
sive subarea of chemical technology. Here as elsewhere in
Ullmann, the large number of references to important literature
sources contributes to the large content of information.
Summarizing, it remains only to state that in its new form
too Ullmann is an essential source of information for all
concerned with chemical-industrial problems. In addition, the
work will be a valuable tool for the scientist engaged in
pure research, for instance when he is interested in the purity
and composition of industrial products or in their toxicity.

Methods of Enzymatic Analysis. Edited by H. U. Bergmeyer.
4 Volumes. Verlag Chemie GmbH, Weinheim/Academic
Press, New York 1974. 2nd English Edition. Total of 2626
pp., numerous figures and tables. Individual price 8 56
per volume. Set price 8 198 for all four volumes.
Eleven years after the first English edition we have the
second edition of “Methods of Enzymatic Analysis” by H .
U . Bergrneyer, this time in collaboration with K . Gawehn.
This reference book with its participation of 240 authors
has long since become the standard work, and the editor
has used the opportunity provided by the need for a new
edition to bring it completely up to date. The general subdivision of the book and the clear presentation of its contents
remain unchanged. The introduction of additional chapters
has increased its size, but not very greatly; tautening the
text in many places and omission of outdated material have
prevented unnecessary bulk. The expansion of the references
listed, almost throughout the work and including publications
of very recent date, is most welcome.
The general introduction to the fundamentals of enzyme
analysis has been considerably expanded and improved. There
are new chapters on reaction kinetics in general and on the
kinetics of enzymatic reactions in particular, as well as a
chapter on methods of determining Michaelis and inhibitor
constants. The text has been kept concise and is very well
suited for recapitulation by the advanced student and as an
introduction to practical work by the beginner. Moreover,
the “Experimental” chapter in the general introduction has
been revised and somewhat expanded. New experimental directions, description of a rapid automatic analyser, and new
values for the extinction coefficients of reduced pyridine nucleotides (they are a few percent higher then previously) are
examples ofcareful work performed by the authors and editors.
Section B of the book, devoted to biochemical reagents,
has been rearranged. It begins with a new chapter in which
the nomenclature and problems of standardization, concepts
of quality of biochemical reagents, and their sources of supply,
are discussed; these are followed by descriptions of enzymes,
coenzymes, and substrates and by final collation of the reagents
in the approved way.
Section C is concerned with methods of measuring enzyme
activities and Section D deals with methods of determining
metabolites. These two are only slightly altered, for example
by transposing individual enzymes so that they correspond
to the new arrangement in the IUB Enzyme Catalog 1973,
or by replacing some old methods of determination by
improved processes.
Summarizing, it can be stated that in its present form the
book needs hardly any fundamental improvement, only that
it maintain its high quality.

The present volume 8 of the new edition of “Ullmann”[*]
is the second in the alphabetical part which, treating the
whole field of technical chemistry under alphabetically
arranged keywords, forms the major part of the encyclopedia.
Here are found not only inorganic and organic starting materials, intermediates and chemicals, raw materials, metals, and
polymers, but also application-oriented areas such as dyestuffs,
fibers, pharmaceuticals, cosmetics, pesticides, and foodstuffs.
An impression of the range of materials covered by Ullmann
can be obtained from a brief look at the more important
keywords in the present volume: from inorganic chemistry
there are the elements antimony, arsenic, barium, beryllium,
lead (Blei), boron, bromine, and their industrially interesting
compounds; from the field of organic intermediates there
are ethanol, aliphatic ethers, ethylene and several of its derivatives such as ethylene oxide, ethylene glycol, ethylene chlorohydrin, ethanolamine, and ethyleneimine, as well as benzene
and some of its derivatives; to these must be added the keywords for materials with special applications, namely antioxidants, asbestos, building materials, bitumen, bleaches, and
dyes of the azine and azo series; finally, in the range of
biological products and processes we have the keywords biotechnology, bread and other bakery products, beer, and
blood-blood
needed in medicine not only in the fresh or
preserved state for transfusions but also as a raw material
for the proteins that are fractionated out of it for special
therapeutic applications.
The entry on ethanol also includes drinks obtained by distillation from the products of alcoholic fermentation. Of general
interest under this keyword is the section “Physiology and
Toxicology”: there we learn, inter alia, that in flying accidents
with a lethal outcome 35-40% of the pilots were ethanol-positive, and that alcohol increases, and sometimes even potentiates, theaction of all the old and new depressant psychopharmaceuticals, especially barbiturates.
The entry on biotechnology deserves special attention. Its
inclusion shows that the present state of knowledge is kept
in mind not only in the content of the entries but also in
the conception of the work as a whole. This entry shows
particularly well how clarity in subdivision and presentation,
in places by tabulated reviews, can lead to a compressed
but nevertheless very easily apprehended summary of an exten-
