Book Description
Twin polymerization is a novel approach where two distinct polymers are produced from a single source monomer, thus being an excellent tool for the synthesis of hybrid materials. The author introduces the principles of various twin polymerization processes, their classification and practical use. The book is supplied with numerous individual examples, demonstrating the potential of this strategy in materials synthesis.

Book Description
Awarded the Literature Prize of the VCI This comprehensive textbook describes the synthesis, characterization and technical and engineering applications of polymers. Polymers are unique molecules and have properties different from any other class of materials. We encounter them in everyday life, not only in the form of the well-known, large-volume plastics such as PE or PP or the many other special polymers, some of which are very specifically modified but also in nature as polymeric biomolecules, such as DNA. Our life, as we know it, would not only be completely different without macromolecules but it would also be biologically impossible. This textbook provides a broad knowledge of the basic concepts of macromolecular chemistry and the unique properties of this class of materials. Environmentally relevant topics, such as biopolymers and microplastic, which should not be missing in a contemporary textbook are also covered. Building on basic knowledge of organic chemistry and thermodynamics, the book presents an easy-to-understand yet in-depth picture of this very dynamic and increasingly important interdisciplinary science that involves elements of chemistry, physics, engineering, and the life sciences. Readers of this work can confirm their understanding of the text at the end of each chapter by working through a selection of exercises. In writing the book, great importance was attached to good readability despite the necessary depth of detail. It is a book that is just as suitable for students of chemistry and related courses as it is for the applied scientist in an industrial environment. The first edition of this work is so far the only textbook on polymer chemistry to be awarded the Literature Prize of the Fund of the German Chemical Industry Association in 2015.

Book Description
Thoroughly revised edition of the classic text on polymer processing The Second Edition brings the classic text on polymer processing thoroughly up to date with the latest fundamental developments in polymer processing, while retaining the critically acclaimed approach of the First Edition. Readers are provided with the complete panorama of polymer processing, starting with fundamental concepts through the latest current industry practices and future directions. All the chapters have been revised and updated, and four new chapters have been added to introduce the latest developments. Readers familiar with the First Edition will discover a host of new material, including: * Blend and alloy microstructuring * Twin screw-based melting and chaotic mixing mechanisms * Reactive processing * Devolatilization--theory, mechanisms, and industrial practice * Compounding--theory and industrial practice * The increasingly important role of computational fluid mechanics * A systematic approach to machine configuration design The Second Edition expands on the unique approach that distinguishes it from comparative texts. Rather than focus on specific processing methods, the authors assert that polymers have a similar experience in any processing machine and that these experiences can be described by a set of elementary processing steps that prepare the polymer for any of the shaping methods. On the other hand, the authors do emphasize the unique features of particular polymer processing methods and machines, including the particular elementary step and shaping mechanisms and geometrical solutions. Replete with problem sets and a solutions manual for instructors, this textbook is recommended for undergraduate and graduate students in chemical engineering and polymer and materials engineering and science. It will also prove invaluable for industry professionals as a fundamental polymer processing analysis and synthesis reference.

Book Description
This book presents key research findings on the combination of different technologies that promise to be particularly sustainable and broadly impactful in their application. The findings were compiled during the course of the first funding period for the MERGE Cluster of Excellence. New methods, potential solutions, and exemplary pilot applications take center stage as the text explores the next generation of functional integration via lightweight structures. The underlying manufacturing processes are based on textile, polymer, and metal processing techniques, all of which are suitable for large batch production, flexibility, and reproducibility.

Book Description
Extrusion is by far the most important and the oldest processing and shaping method for thermoplastic polymers. This process concerns almost all synthetic polymers, as well as elastomers or food materials. Single-screw extrusion is mainly used nowadays to manufacture finished goods or semi-finished products. More than 90 million tons of thermoplastics are therefore processed every year. Twin-screw extrusion may be divided into two systems: contra-rotating systems used within the context of PVC extrusion, for the manufacture of pipes or profiles; and co-rotating systems experiencing nowadays a very significant development, because of their significant adaptability and flexibility, which enables the manufacture of specific materials (polymer alloys, thermoplastic elastomers, filled polymers, nanocomposites). Extrusion is carried out by passing molten polymer through a tool called die that will give the product its final shape (films and sheets, rolled products, and electric cables). Thanks to the design of dies, we obtain at the output a product with controlled dimensions, uniform speeds and homogeneous temperatures. The book will discuss the same production types, but only in the case of coextrusion flows, i.e. multilayer stratified products. First of all, we will present in this book the physics of the mechanisms at stake, then propose more or less complex models in order to describe these mechanisms and then go forward in the interpretation of results and the control of condition flows.

Book Description
From Reports in Volume 5: "Recently polymer blends have emerged as one of the most important areas of research activity in the field of polymer science and technology. Because of their satisfactory performance in meeting specific needs of the polymer industry, they have drawn considerable attention in replacing not only many conventional materials, but also some of the polymers that are in vogue. By suitably varying the blend compositions and manipulating the processing conditions, tailor-made products with a unique set of end use properties can be achieved at a much lower cost and within a shorter time than would have been necessary for the development of a new polymer. The usefulness of such blends increases with the increasing range of applications of this type of materials." (Chapter 4) "New and growing demands on polymeric materials cannot be satisfied in future by an assortment extension of basic polymers. Although the introduction of new major-use basic polymer is possible, it seems unlikely in view of current projected economic and technical considerations. On the other hand, new products based on the modification of existing polymers have and will continue to be fruitful areas for both scientific and commercial developments. The driving forces for these developments are: 1. Improved performance, 2. Reduced cost, 3. Present, pending and future legislation dealing with health and environmental issues." (Chapter 11)
