Download or read book Polypropylene written by J. Karger-Kocsis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 988 pages. Available in PDF, EPUB and Kindle. Book excerpt: My heart sank when I was approached by Dr Hastings and by Professor Briggs (Senior Editor of Materials Science and Technology and Series Editor of Polymer Science and Technology Series at Chapman & Hall, respectively) to edit a book with the provisional title Handbook of Poly propylene. My reluctance was due to the fact that my former book [1] along with that of Moore [2], issued in the meantime, seemed to cover the information demand on polypropylene and related systems. Encour aged, however, by some colleagues (the new generation of scientists and engineers needs a good reference book with easy information retrieval, and the development with metallocene catalysts deserves a new update!), I started on this venture. Having some experience with polypropylene systems and being aware of the current literature, it was easy to settle the titles for the book chapters and also to select and approach the most suitable potential contributors. Fortunately, many of my first-choice authors accepted the invitation to contribute. Like all editors of multi-author volumes, I recognize that obtaining contributors follows an S-type curve of asymptotic saturation when the number of willing contributors is plotted as a function of time. The saturation point is, however, never reached and as a consequence, Dear Reader, you will also find some topics of some relevance which are not explicitly treated in this book (but, believe me, I have considered them).

Download or read book Rheology for Polymer Melt Processing written by J.-M. Piau and published by Elsevier. This book was released on 1996-10-10 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the main results obtained by different laboratories involved in the research group Rheology for polymer melt processing which is associated with French universities, schools of engineering, and the CNRS (Centre National de la Recherche Scientifique - France). The group comprises some 15 research laboratories of varied disciplines (chemistry, physics, material sciences, mechanics, mathematics), but with a common challenge viz. to enhance the understanding of the relationships between macromolecular species, their rheology and their processing. Some crucial issues of polymer science have been addressed: correlation of viscoelastic macroscopic bulk property measurements and models, slip at the wall, extrusion defects, correlation between numerical flow simulations and experiments. Features of the book: • The book is unique in that it allows one to grasp the key issues in polymer rheology and processing at once through a series of detailed state-of-the-art contributions, which were previously scattered throughout the literature. • Each paper was reviewed by experts and the book editors and some coordination was established in order to achieve a readable and easy access style. • Papers have been grouped in sections covering successively: Molecular dynamics, Constitutive equations and numerical modelling, Simple and complex flows. • Each paper can be read independently. Since the book is intended as an introduction to the main topics in polymer processing, it will be of interest to graduate students as well as to scientists in academic and industrial laboratories.

Download or read book Polymer Melt Processing written by Morton M. Denn and published by Cambridge University Press. This book was released on 2008-08-04 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the shaping in the manufacture of polymeric objects is carried out in the melt state, as it is a substantial part of the physical property development. Melt processing involves an interplay between fluid mechanics and heat transfer in rheologically complex liquids, and taken as a whole it is a nice example of the importance of coupled transport processes. This book is on the underlying foundations of polymer melt processing, which can be derived from relatively straightforward ideas in fluid mechanics and heat transfer; the level is that of an advanced undergraduate or beginning graduate course, and the material can serve as the text for a course in polymer processing or for a second course in transport processes.
Download or read book Fracture Behaviour of Polymers written by A.J. Kinloch and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over recent years there has been a tremendous upsurge in interest in the fracture behaviour of polymers. One reason for this is the increas ing use of polymers in structural engineering applications, since in such circumstances it is essential to have as complete an understanding as possible of the polymer's fracture behaviour. This book is designed to meet the requirements of those who need to be informed of the latest developments in the field of polymer fracture. It is written particularly for research workers but it should also prove invaluable for advanced students taking final-year undergraduate or postgraduate courses. The main emphasis is upon the use of fracture mechanics in the study of polymer fracture but this approach is then developed to cover the micromechanisms of the fracture process. Particular prominence is given to the relationship between structure, mechanical properties and the mechanics and mechanisms of fracture. The first chapter is a brief introduction which has several aims. One is to introduce polymers to the reader who does not have a strong background in the subject and another is to provide background material that will be used at later stages. The book is then split into two main parts: the first deals with the mechanics and mechanisms whilst the second is concerned with materials. In Part I phenomena such as molecular fracture, fracture mechanics, shear yielding and crazing are covered from a general viewpoint.

Download or read book Principles of Polymer Processing written by Zehev Tadmor and published by John Wiley & Sons. This book was released on 2013-12-02 with total page 1004 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Standard Pressure Volume Temperature Data for Polymers written by David Walsh and published by CRC Press. This book was released on 1995-08-24 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Introduction PVT data consists of records of the specific volume of a material (or its inverse, the density) as a function of pressure and temperature. There are many reasons why the specific volume of a material will undergo changes: changes in the temperature and pressure (thermal expansion and compression), phase changes (solid-solid phase transitions, melting, crystallization, glass transitions, mesophase transitions), degradation reactions, and many more. Conversely, PVT measurements can be used to study these phenomena and also to yield derivative data of direct importance to engineering applications of materials (compressibility, bulk modulus, thermal expansivity, etc.). PVT methods are part of a wide array of thermoanalytical techniques available to scientists and engineers, but PVT is the only commonly practiced technique that includes pressure as a variable. Polymers are sensitive to pressure: the volume itself, the pressure dependence of transition temperatures, and the kinetics of phase transitions are all significant, not only from a scientific point of view, but also for practical applications in polymer engineering, such as processing. Now published. This unique polymer reference book will be useful to all those involved in polymer research and advanced engineering. The more than 350 tables and graphs provide a wealth of important data in easy-to-use form. The introductory chapter provides details on methodology, equipment use, and information on the many ways in which PVT data can be used in research and engineering.
