BOOK EXCERPT:

From the Author's Preface There is a growing demand for ultrapure organic compounds such as fine chemicals, pharmaceuticals, and basic materials for use in the polymer industry. . . . In quite a number of cases, it is difficult or impossible to manufacture ultrapure organics efficiently using conventional separation techniques such as distillation. Moreover, conventional techniques usually require large amounts of energy. To improve the purification efficiency of organics, special techniques based on crystallization from the melt have been developed. Melt crystallization meets industry's need for a highly selective separation process for organic compounds which operates at low enough temperatures to prevent thermal degradation. Melt crystallization processes have the added advantage that they are energy-efficient and ecologically sound. Melt crystallization techniques appear to be particularly promising for upgrading organic materials and are one of the few routes that appear to be feasible for purifying starter materials for high-tech polymers. The aim of this book is to provide basic information on melt crystallization technology. . . . This monograph consists of three parts: 1. basic principles, 2. process options, and 3. technical equipment and applicability. This new book is the first unified guide and reference to an important chemical process technology. It is comprehensive and organized for easy reference. More than 150 diagrammatic representations, flow charts and photographs illustrate equipment and processes. More than 40 tables provide useful reference data. The Author Dr. Arkenbout studied chemistry at the University of Utrecht, and joined TNO, the Netherlands Organization for Applied Scientific Research. He has specialized in research on new separation processes and has had thirty of his articles on this subject published. He recently retired from the position of manager of physical separation research, but has remained active in this field through affiliations with the Laboratory of Solid State Chemistry at the University of Nijmegen, the Laboratory for Process Equipment, Delft University of Technology, and TNO.

BOOK EXCERPT:

Fiber Crystal Growth from the Melt reviews the growth, modelling, characterization and application of single crystal fibers. Due to their very large length-to-diameter ratio together with perfect crystallographic structure and chemical homogeneity, such fibers have mechanical and physical properties that approach the theoretical values. Fukuda explains how their ultra-high strength enables their application as reinforcing agents in structural components. And he elucidates how and why fiber crystals are particularly well suited for wave guiding, tunable narrow-band filters and nonlinear optics and for the generation of green, blue and violet wavelenghts, and also as micro lasers and laser modulators.

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 EXCERPT:

This book is devoted to a nontraditional class of materials which are manufactured by the melt-blowing process - i.e. by extrusion of polymer melt followed by fiber stretching with a gas stream. For the first time extensive data on classical and modern modifications of this technology are generalized and a review is given of extrusion head dies and subsidiary equipment. The text examines the structure and main properties of melt-blown materials as conditioned by peculiarities of overheated polymer melt spraying in an oxidizing medium. Information is given about filtering mechanisms and the main types of polymer fibrous filtering materials: electret, magnetic, adsorptional, bactericidic, and about carriers of microorganisms in biofilters. Social and ecological aspects of the application of melt-blown materials are analyzed.

BOOK EXCERPT:

The continually growing plastics market consists of more than 250 million tons of product annually, making the recurring problem of polymer melt fracture an acute issue in the extrusion of these materials. Presenting a pictorial library of the different forms of melt fracture and real industrial extrusion melt fracture phenomena, Polymer Melt Fracture provides pragmatic identification and industrial extrusion defect remediation strategies based on detailed experimental and theoretical findings from the last 50 years. Distinct microscopic photos Each chapter in this comprehensive volume covers a different aspect of the science and technology relating to polymer melt fracture. The book begins with a collection of optical and scanning electron microscopy pictures. These photos show distorted capillary die extrudates for a number of commercially available polymers. The authors present a brief introduction to the basic science and technology of polymers. They explain what polymers are, how they are made, and how they can be characterized. They also discuss polymer rheology, review the principles of continuum mechanics, and define linear viscoelastic material functions. Techniques for observing and measuring fracture Next, the book explains how polymer melt fracture is actually experienced in the polymer processing industry. It explains the various ways polymer melt fracture may appear during polymer melt processing in different extrusion processes. The authors provide comprehensive reviews of the polymer melt fracture literature, with chapters on experimental findings and the techniques used to observe and measure polymer melt fracture, and the influence of polymer architecture and polymer processing conditions on the onset and types of polymer melt fracture. Posing a hypothesis about the phenomenon, the book presents the current understanding of polymer melt fracture. Mathematical equations Recognizing the importance of models for simulations that may indicate potential solutions, the book discusses aspects of non-linear constitutive equations and microscopic theory and develops a macroscopic model, explaining the capabilities and limitations of this approach. The book presents an overview of pragmatic tools and methods that have been used to prevent the appearance of polymer melt fracture and explains how to use them to suppress defects.

Poetry. "Writing from near the Arctic Circle. the marvelous Derick Burleson has wrought an erotic masterpiece. MELT is a metaphor for that which lives on in us against impending loss—sexual and precise, full of the images of the ever thawing earth. He enacts through lyric language a new way of seeing for our survival, immersed in the joy and joining of our human bodies, because 'after all the phosphorescent / beings beneath your separate / skins mountains and glaciers / too beautiful to live beneath.' You could die of beauty here."—Sean Thomas Dougherty "The sense-drenched offerings in MELT once again cement Derick Burleson's role as unflinching witness, a master spinner of huge tales in tiny spaces. The insistent lyrical current that pulses through these deftly-forged stanzas create a music that will immediately enthrall and captivate the reader. Burleson is a startlingly good poet who burns down borders with every word."—Patricia Smith
