This book was released on 2013-11-27 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid crystal polymers (LCPs) have many strange properties that may be utilized to advantage in the processing of products made from them and their blends with isotropic polymers. This volume (volume 2 in the series Polymer Liquid Crystals) deals with their strange flow behaviour and the models put forward to explain the phenomena that occur in such polymers and their blends. It has been known for some time that small ad ditions of a thermotropic LCP to isotropic polymers not only gives an improvement in the strength and stiffness of the blend but improves the processability of the blend over that of the isotropic polymer. In the case of lyotropic LCPs, it is possible to create a molecular composite in which the reinforcement of an isotropic polymer is achieved at a molecular level by the addition of the LCP in a common solvent. If the phenomena can be fully understood both the reinforcement and an increase in the proces sability of isotropic polymers could be optimized. This book is intended to illustrate the current theories associated with the flow of LCPs and their blends in the hope that such an optimization will be achieved by future research. Chapter 1 introduces the subject of LCPs and describes the ter minology used; Chapter 2 then discusses the more complex phenomena associated with these materials. In Chapter 3, the way in which these phe nomena may be modelled using hamiltonians is fully covered.

Book Synopsis Thermotropic Liquid Crystal Polymer Blends by : Francesco Paolo La Mantia
Download or read book Thermotropic Liquid Crystal Polymer Blends written by Francesco Paolo La Mantia and published by CRC Press. This book was released on 1993-12-04 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, studies by both industry and academic researchers have opened the door to improving performance and reducing costs of these new materials. The particular structure and morphology of LCPs, as well as their peculiar rheological behavior, have stimulated researchers to develop new theoretical models and new characterization and processing techniques to more fully understand and utilize LCPs. Although the scientific literature is very rich in data on the synthetic techniques and on the relations between structure and phase behavior of these new polymers, the understanding of the rheological and processing aspects is still far from satisfactory-particularly in the case of LCP blends. In fact, although an appreciable number of patents and scientific papers have appeared describing the phase behavior, the rheology, and the mechanical properties of many of these polyblends, several aspects of the relations between processing and morphology, and between morphology and properties of these materials are still obscure or even controversial. Now, this new book, written by leading researchers, provides an up-to-date guide and reference to the processing, rheology and applications of pure LCPs and LCP blends. The book concisely reviews the synthetic procedures for the production of LCPs and discusses the rheological behavior and processing methods. Plus, the book examines present and future applications areas of LCPs and LCP blends.

Book excerpt: Rheology is the study of the flow of matter, primarily in the liquid state, but also as 'soft solids' or solids under flow conditions in which they respond with plastic flow rather than deforming elastically in response to the applied force. An understanding of the flow of matter underpins a diversity of technologies and industrial processing including polymer and food processing. It applies to substances which have a complex microstructure, such as concentrated solutions, suspensions, polymers and inorganic glass formers as well as biological materials which belong to the class of soft matter. Rheological measurements are seemingly straightforward to make, but require models to interpret the mechanical measurements in terms of the microscopic behaviour of the material. This boo draws these diverse strands of current rheological research in to a single volume which embraces theory, measurement and applications in topics as diverse as theory and electrospinning, coal ash slag and food processing, hydrogels and liquid crystal polymers, reaction injection moulding and microreheology.There is a strong focus on the emerging topics in rheology and its application to complex soft matter especially in the field of food science and technology. The sixteen chapters in the volume present unpublished research work across these topics from leading authorities in the relevant field. The volume has a strong international representation with the selected authors drawn from some ten countries in Europe, South America and the rest of the world. Each chapter contains a comprehensive bibliography of related work. The book provides a fascinating snap shot across the current developments in rheology.

Book Synopsis Melt Rheology and Its Role in Plastics Processing by : K. Wissbrun
Download or read book Melt Rheology and Its Role in Plastics Processing written by K. Wissbrun and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to fulfill a dual role. On the one hand it provides a description of the rheological behavior of molten poly mers. On the other, it presents the role of rheology in melt processing operations. The account of rheology emphasises the underlying principles and presents results, but not detailed deriva tions of equations. The processing operations are described qualita tively, and wherever possible the role of rheology is discussed quantitatively. Little emphasis is given to non-rheological aspects of processes, for example, the design of machinery. The audience for which the book is intended is also dual in It includes scientists and engineers whose work in the nature. plastics industry requires some knowledge of aspects of rheology. Examples are the polymer synthetic chemist who is concerned with how a change in molecular weight will affect the melt viscosity and the extrusion engineer who needs to know the effects of a change in molecular weight distribution that might result from thermal degra dation. The audience also includes post-graduate students in polymer science and engineering who wish to acquire a more extensive background in rheology and perhaps become specialists in this area. Especially for the latter audience, references are given to more detailed accounts of specialized topics, such as constitutive relations and process simulations. Thus, the book could serve as a textbook for a graduate level course in polymer rheology, and it has been used for this purpose.

Book Synopsis Thermotropic Liquid Crystal Polymers by : Tai-Shung Chung
Download or read book Thermotropic Liquid Crystal Polymers written by Tai-Shung Chung and published by CRC Press. This book was released on 2001-03-01 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid crystal polymers are sometimes called super polymers--with good reason. Their wide range of exceptional properties and ease of processing make them design candidates for many demanding applications. This new book provides a thorough review of LCP technology with the emphasis on the chemistry, synthesis and characterization of the material in its many variants. Additional chapters cover processing and applications. From the Editor's Preface The field of thermotropic liquid crystalline polymers has grown substantially in the last two decades, with fundamental research, publications, commercial products, and patents. In the 1980's, Dr. Ralph Miano led my colleagues and me at Hoechst Celanese in commercializing the first thermotropic liquid crystalline polymers, based on Dr. Gordon Calundann's composition patents. Today, more than seven companies have produced thermotropic liquid crystalline polymer materials, with at least 50 variants available. Hence, it is timely to compile a comprehensive review on the nature of this type of material and the ongoing progress in this field.... The goals of this book are to summarize previous work, provide new insights into this class of polymers, and add to the understanding of the formation of liquid crystallinity. This book covers a wide range of topics and addresses different disciplines in the field. The chapters are arranged as a learning scheme for the professional, from basic science to applied engineering. The first few chapters summarize the syntheses of various polyester, polyester-amid, and polyimide liquid crystalline polymers. The science and origins of liquid crystal formation are revealed. Next, we introduce the characterizations of these materials by their different chemical and physical aspects. Because most commercially available thermotropic liquid crystalline polymers have been used in the form of composites, we have also incorporated a chapter on polymer blends, detailing blending mechanisms and resultant properties. Two chapters on thermosetting liquid crystalline polymers integrate them with other topics, because of their unique importance and their applications for microelectronics and packaging. The final chapter deals with the engineering and processing aspects of thermoplastic liquid crystalline polymers for a variety of applications.
