Biopolymers represent a carbon emission solution: they are green and eco-friendly with a variety of uses in biomedical engineering, the automotive industry, the packaging and paper industries, and for the development of new building materials. This book describes the various raw materials of biopolymers and their chemical and physical properties, the polymerization process, and the chemical structure and properties of biopolymers. Furthermore, this book identifies the drawbacks of biopolymers and how to overcome them through modification methods to enhance the compatibility, flexibility, physicochemical properties, thermal stability, impact response, and rigidity.
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)
This book is based on invited presentations at the Ninth International Catecholamine Symposiwn. Over several decades, each International Catecholamine Symposiwn (ICS) has provided a uniquely important forwn for updating basic as well as clinical research on the catecholamines, dopamine, norepinephrine, and epinephrine. The first ICS took nd n1 place in Bethesda, Maryland, in the USA in 1958; the 2 in Milan, Italy in 1965; the 3 th in Strasbourg, France in 1973; the 4th in Asilomar, California, USA in 1978; the 5 in th th Goteborg, Sweden in 1983; the 6 in Jerusalem, Israel, in 1987; the 7 in Amsterdam, th Netherlands in 1992; and the 8 in Asilomar, California, USA in 1996. th The 9 International Catecholamine Symposiwn (9ICS) was held in Kyoto, Japan, th March 31-April 5, 2001. This ICS was held concurrently with the 5 International th Conference on Progress in Alzheimer's and Parkinson's Disease (5 ADPD). These international meetings were coordinated to be a joint international congress. Catecholamines and related neurotransmitters and neuromediators play important roles in the pathogenesis of symptoms and neurodegenerative processes of Alzheimer's disease and Parkinson's disease. Therefore, the Joint Congress provided an opportunity for investigators and clinicians working in these fields to exchange their. most recent investigational results and clinical experiences. This Joint International Congress turned out to be an enormous success, attended by 1258 participants from 38 countries, in an enthusiastic and pleasant atmosphere."

Thermal Analysis (TA) has become an indispensable family of
analytical techniques in the polymer research. The increased
importance of these techniques can be seen as the result of three
more or less parallel developments: These areas are still in their developmental stages, especially
the third area. The increasing knowledge of the dependence of
physical properties on chemical structure just accentuated more and
more the need for accurate thermoanalytical measurements, and this
knowledge is very important for the first stages of the development
of new polymeric systems. Besides, the contribution of TA remains
necessary for the technical and commercial development of such a
new polymer system. The use of the various TA techniques in these
processes is described in this book in nine chapters, while chapter
ten illustrates the information obtained about different polymers
during special case studies. This book illustrates in this way, applications of a wide
variety of TA techniques whilst it is written from a materials
characterisation rather than from a TA point of view with attention
being paid to the chemical structure/physical properties
correlations.

This new book explores the consideration of relationships that connect the structural and basic mechanical properties of polymeric mediums within the frameworks of fractal analysis with cluster model representations attraction. Incidentally, the choice of any structural model of medium or their combinations is defined by expediency and further usage convenience only. This book presents leading-edge research in this rapidly changing and evolving field. The book presents descriptions of the main reactions of high-molecular substances within the frameworks of fractal analysis and irreversible aggregation models. Synergetics and percolation theory were also used. In spite of the enormous number of papers dealing with the influence of the medium on the rate of chemical reactions (including synthesis of polymers), no strict quantitative theory capable of "universal" application has been put forward up until now. It is now possible to describe the relationship between the reaction rate constants and the equilibrium constants with the nature of the medium in which the reactions take place by means of a single equation. This important book for the first time gives structural and physical grounds of polymers synthesis and curing, and the fractal analysis is used for this purpose.

This thesis identifies the turning point in chain length, after which alkanes self-solvate into a folded structure instead of an extended stretched conformation. After this turning point, London dispersion forces rearrange isolated n-alkanes into a particular hairpin-structure, while for shorter chain lengths, a simple stretched conformation is energetically preferred. This thesis can locate the experimental turning point for the first time in an interaction-free manner from measurements of unbranched alkanes at low temperatures in supersonic jet expansions. It contains a detailed analysis of the vibrational Raman spectra of the chain molecules, which is supported by comprehensive quantum chemical simulations. In this way, the detailed balance between inter-chain attraction and conformational flexibility can be quantified. The investigations are complemented by measurements of perfluoroalkanes and similarities and differences between the compounds are discussed. Furthermore, Nils Luttschwager determines the stiffnesses (elastic moduli) of two of the most common industrial polymers: polyethylene and polytetrafluorethylene. He uses in this thesis a sophisticated extrapolation to calculate this value from quantities of their building blocks, showing that the single polymer molecules can be as stiff as a rod of steel.
