Book Description
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)

Book Description
The molecules of block and graft copolymers are molecules of a higher order; they consist of homopolymer subchains which are interconnected by chemical valence bonds. This structural com plexity is manifested in the unusual behavior of block and graft copolymers both in solution and in bulk. Many types of interac tions are possible in block and graft copolymers in the solid state. Polymer subchains of one molecule can interact with other polymer subchains which may belong to the same molecule or to different molecules. Since polymer chains of chemically different composition are usually incompatible, thermodynamically unfavorable as well as thermodynamically favorable interactions exist in the solid state. In solutions of block and graft copolymers, the sit uation becomes even more complex, because interactions between the solvent molecules and the various subchains of the copolymer mole cules occur in addition to the interactions between the polymer chains. This multitude of interactions gives rise to a wide spec trum of colloidal and morphological properties which have no paral lel in less complex polymer systems such as homopolymers or random copolymers. Research on the colloidal and morphological behavior of block and graft copolymers is a relatively new field of endeavor. It started in 1954, when F. M. Merrett fractionated mixtures of grafted na tural rubber with the corresponding homopolymers and observed that colloidal sols were formed at certain points during his fractional precipitations.

Book Description
Modified Polymers, Their Preparation and Properties brings together the main lectures presented at the Fourth Bratislava Conference on Polymers held in Bratislava, Czechoslovakia, on July 1-4, 1975. Contributors explore the properties of modified polymers and their preparation, covering topics ranging from radiation crosslinking of polyvinyl chloride (PVC) with ethylene glycol dimethacrylate to chemical modification of polymers and the influence of chemical structure on the properties of polymers. This book is comprised of eight chapters and begins with a discussion on crosslinking of PVC in the presence of ethylene glycol dimethacrylate, studied by microcalorimetry, electron spin resonance, and structure investigation. The next chapter examines some characteristic features of chemical transformations of polymers on three examples: reactions of various organo-lithium bases onto the ester carbonyls of polymethylmethacrylate (PMMA); reaction of phenyl-lithium onto the carbonyl groups of PMMA; and chemical modification of polyvinylalcohol by metallation and subsequent reactions of alkylhalides or of propane sulfone. Subsequent chapters focus on how chemical structure affects polymer properties; alternating copolymer graft copolymers; acrylonitrile block and graft copolymers; and problems of polymer modification and the reactivity of functional groups of macromolecules. The final chapter is devoted to the separation and characterization of block and graft copolymers by thin-layer chromatography. This monograph will be a valuable source of information for chemists.

Book Description
Growing interest in the formulation of pressure-sensitive adhesives as described in the first edition of this book ( Pressure-Sensitive Formulation, VSP, 2000) required a new, enlarged edition including the design of pressure-sensitive adhesives as a separate volume. Developments in the understanding of pressure sensitivity were necessary to use macromolecular chemistry for pressure-sensitive design. Such developments include polymer physics and contact mechanics. Progress in coating technology, especially in in-line coating- and synthesis, opened new ways for the design of pressure-sensitive adhesives and products as well. Actually, pressure-sensitive-products with and without adhesives compete requiring a broad variety of material formulations and the corresponding manufacturing technology. The first volume of the book examines the theoretical aspects of pressure-sensitive design, based on macromolecular chemistry, macromolecular physics, rheology and contact mechanics. The second volume describes the practical aspects of pressure-sensitive design and formulation, related to product application. The advances in the various domains are described by specialists.

Book Description
This book elucidates the peculiar phenomenon of entropy/enthalpy compensation that takes place in high performance liquid chromatography (HPLC) of polymers. Numerous publications, including some books, are devoted to molecular characterization of synthetic polymers, materials presently produced in large and steadily growing quantities, applying methods of HPLC. A knowledge of the molecular characteristics of polymers is indispensable, not only for their proper applications but also for their recycling and remediation. Polymer scientists generally focus on synthesis and potential applications of polymers while not giving due attention to an important central link, their comprehensive characterization in context of development of structure-property correlations. To fill this gap is one of the aims of the present book. The process of entropy/enthalpy compensation plays a decisive role in the advanced method of polymer characterization such as liquid chromatography at critical conditions, eluent gradient interaction chromatography, and temperature gradient interaction chromatography. All chemists working on any aspect of polymer science will find this book a valuable resource for the development of structure-property correlations.
