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 Rheo Physics of Multiphase Polymer Systems written by Kai Sondergaard and published by CRC Press. This book was released on 1995-06-02 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: FROM THE PREFACE Almost all polymeric systems are subjected to a flow field at least once along the route between preparation and application. . . . There is also an increased interest in predictive models on phase behavior and suitable techniques for characterizing the structure of these systems when subjected to flow. Multiphase polymeric systems are particularly susceptible to flow, which may cause orientation of species, morphological changes, and phase transitions. All these events may, in turn, affect the end product properties, such as permeability, electrical conductivity, [and] mechanical properties. In processing, escalating needs have evolved for optimization and development of novel and more uniform product properties and increased productivity. In order to arrive at an understanding of processing polymeric systems under elastic flow conditions, it is convenient to analyze the basic physical mechanisms under conditions that enable development of predictive models in conjunction with controlled experimentation. . . . In recent years, the science of rheo-physics has evolved and now involves both advanced theories and experimental techniques. Rheo-physics means the rheological, morphological, and thermodynamic behavior of structured polymer systems during flow. . . . In this monograph, the rheo-optical techniques are . . . emphasized. The book gives an introduction to rheo-physics, including fundamentals of theories, and a representative selection of applications of rheo-optical techniques for analyzing multiphase systems. The chapters contain both practical advice for the new experimenter . . . as well as review material for the experienced scientist.

Download or read book Properties of Crystalline Polyethylene like Materials Under Industrially Relevant Processing Conditions written by Carlos Germosen Polanco and published by . This book was released on 2021 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyethylene-like materials with in-chain acetal units ( -O-CH2-O- ) precisely spaced by long methylene runs (between 12 and 26 CH2) crystallize from the melt in four different crystallographic forms (polymorphs) depending on the depth of undercooling. Using a Fast Scanning Calorimeter (FSC) we determined the critical cooling rates needed to develop the lowest temperature polymorphs from the melt, the mesomorphic-like disordered and hexagonal structures. The crystallization kinetics of high-temperature polymorphs, Forms I and II were obtained by classical DSC, and the crystallization kinetics of the low-temperature polymorphs, disordered, and hexagonal have been studied in this work by FSC. Isothermal crystallization studies in a wide range of temperatures revealed minima in the temperature gradient of the overall crystallization rates at all transition temperatures between polymorphs. The minima in the crystallization rates and heat of fusion are attributed to differences in nucleation barrier between polymorphs, and effects of self-poisoning. There is a step increase of melting temperature with increasing structural stability and a continuous increase in melting during annealing at a fixed crystallization temperature. The disordered structure and hexagonal crystals are metastable and upon annealing transform to the next stable phase as shown by a change in WAXD patterns. These kinetics studies serve to identify processing rates and properties of sustainable polyethylene-like materials crystallized at industrially relevant conditions.

Download or read book Crystallization and Melting of Polyethylene Under Pressure written by Theodore Davidson and published by . This book was released on 1968 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crystallization conditions which lead to extended-chain polyethylene under elevated pressure were elucidated further. The dependence of polyethylene density on crystallization pressure on slow cooling was extended up to 6980 bars. No further improvement of crystal perfection or extension of polymer chains were observed. At 5000 bars the temperature of crystallization was varied between 170 to 270C. Temperatures between 195 and 225C were found suitable for crystallization of extended chain polyethylene. A time sequence at 200C and 5000 bar revealed some insight in the formation of extended chain polyethylene. It is thought to involve a two step process of nucleation of folded chain lamellae, followed by solid state chain extension. High pressure differential thermal analysis apparatus has been developed for measurement up to 3700 bar. Folded as well as extended chain crystals of polyethylene were analyzed. Only the extended chain crystals show an initial increase in melting point in accord with the Clausius Clapeyron equation. (Author).
