Emphasis is on a broad description of the general methods and processes for the synthesis, modification and characterization of macromolecules. These more fundamental chapters will be supplemented by selected and detailed experiments. In addition to the preparative aspects the book also gives the reader an impression on the relation of chemical constitution and morphology of Polymers to their properties, as well as on their application areas. Thus, an additional textbook will not be needed in order to understand the experiments.

The 5th edition contains numerous changes: In recent years, so-called functional polymers which have special electrical, electronic, optical and biological properties, have gained more and more in interest. This textbook was therefore supplemented by recipes which describe the synthesis of these materials in a new chapter "Functional polymers." Together with new experiments in chapter 3,4 and 5 the book now contains more than 120 recipes that describe a wide range of macromolecules.

From the reviews of recent editions:

"This is an excellent book for all polymer chemists engaged in synthesis research studies and education. It is educationally sound and has excellent laboratory synthetic examples. The fundamentals are well done for the teaching of students and references are resonably up-to-date. As in previous issues, there are sections dealing with an introduction; structure and nomenclature; methods and techniques for synthesis, characterization, processing and modification of polymers.

....The authors have noted the following changes from previous editions- a new section on correlations of structure, morphology and properties; revision and enlargement of other property and characterization procedures; additional new experiments such as controlled radical polymerization; enzymatic polymerizations; microelmulsions; and electrical conducting polymers.

This is a high quality textbook at a reasonable price and should be considered as a suitable reference for all engaged in synthetic areas of polymer research." (Eli M. Pearce, Polytechnic University, Brooklyn, NY, USA)

Unter den fur die technische Verarbeitung von thermoplastischen Kunststoffen erforderlichen Bedingungen koennen verschiedene chemische Reaktionen ablaufen, von denen die meisten in der Praxis unerwunscht sind, da sie die Qualitat der Fertigprodukte vielfach ungunstig beeinflussen. Trotz der grollen Bedeutung von solchen V organgen fur die Kunststoffverarbeitung fehlt es bisher noch sehr an systematischen Untersuchungen hieruber. In dem vorliegenden Bericht wird daher der Versuch unternommen, die che- mischen Vorgange wahrend der Thermoplastverarbeitung unter einem einheit- lichen Gesichtspunkt darzustellen. Als Grundlage hierfur dienen auller der auf den meisten Teilgebieten nicht sehr umfangreichen Literatur eigene Unter- suchungen, die seit 1960 mit Mitteln des Landes Nordrhein-Westfalen, seit 1963 mit Unterstutzung der ArbeitsgemeinschaftindustrielJer Forschungsvereinigungen (AlF) gefoerdert wurden. An den eigenen Untersuchungen waren zahlreiche Mitarbeiter beteiligt, deren Anteil aus den Zitaten hervorgeht; der Verfasser moechte ihnen allen auch an dieser Stelle fur ihre Hilfe vielmals danken. . Fur die freundliche Genehmigung zur Verwendung der V orlagen fur folgende Abbildungen aus fruheren Veroeffentlichungen des Verfassers sei dem Carl Hanser Verlag, Munchen (Abb. 24 und 25 aus [90]; Abb.2, 3, 4, 7, 13, 14 aus [49]; Abb. 19 aus [80]), dem Huthig und Wepf Verlag, Basel (Abb. 8 aus [19] sowie Abb. 9 und 10 aus [54]) und dem Dr. Dietrich Steinkopf Verlag, Darmstadt (Abb. 31 aus [103]) vielmals gedankt.

Processors and users of plastics often need to determine the chemical nature of a plastics specimen. This highly practical and useful manual, now in a fifth revised and supplemented edition, will enable you to determine the class of plastic of a particular specimen. No extensive knowledge of chemistry is required and yet it is more complex than a simple tabular compilation. This manual is a handy and highly effective tool for many practical situations. An additional supplement is a chapter that shows strategies for identifying historical plastic objects; this is of particular interest for assemblers and collectors, and conservators.

Originally published in German in an edition edited by Dietrich Braun, Karl Barth's Ethics is at last available in English. This volume, containing lectures given as courses at the University at Munster in 1928 and 1929, represents Barth's first systematic attempt at a theological account of Christian ethics. Although composed over fifty years ago, just prior to Barth's thirty-year devotion to Church Dogmatics, many of its themes, problems, and conclusions are astonishingly relevant today (his critique of competitiveness and of technology, for example). While this work is concerned with the foundations of ethics, it also reveals Barth's highly practical interest in ethics and his special concern to avoid legalism and yet to maintain a structured divine command. Barth's ethics are arranged on a Trinitarian basis, dealing in succession with the command of God the Creator (life), the command of God the Reconciler (law), and the command of God the Redeemer (promise). "It is then a work of the greatest interest showing the development of Barth through the liberal period of thought toward a more positive and theologically grounded ethic, which he later developed under the rubric of the command of God." --Thomas F.

Abgestossen vom festen Land, trieb mein Schiff schnell dahin, hinein in die bewegte See des Lebens. Uber Untiefen und Klippen, durch Nebel und schmutziges Wetter wird es segeln zum Guten oder Bosen. Ich war auf alles vorbereitet. Ohne Namen, keinen Pfennig Geld, kein heimatliches Gangelband - es war wirklich mehr, als ich je ertraumt.
