Available in PDF, EPUB and Kindle. Book excerpt: This work targeted to unveil the processing-structure-property relationships of four polymeric systems with diverse transport properties. The first and the second chapters concentrated on a through-pore membrane derived from polypropylene (PP) and polyamide 6 (Nylon 6) blends. The other three chapters discussed the adjustable gas barrier properties in regards to the morphologies of polymer blends and multilayer films. Among all the chapters, gas and liquid transport properties were proved as an effective identifier for the morphology. The change in transport phenomena was strongly correlated with the shift in the structure. In Chapter One and Chapter Two, porous membranes were produced from biaxial orientation of polymer blends comprising PP, Nylon 6, and polypropylene grafted maleic anhydride (PPgMA). During biaxial orientation, the continuous PP domains cavitated while the dispersed Nylon 6 domains remained rigid and spherical. The effect of blend composition on cavitation was analyzed and a ternary diagram generated to identify the composition range for through-pore formation. The membranes were found to have adjustable porosity up to 62% with nanoscale size pores. The membranes show very high filtration efficiency on separating 50 nm Latex microbeads from water suspensions. In Chapter Three, the compatibilization effect of linear low density polyethylene grafted maleic anhydride (LLDPEgMA) and high density polyethylene grafted maleic anhydride (HDPEgMA) on high density polyethylene (HDPE) /Nylon 6 blend system was investigated. HDPEgMA was identified as a better compatibilizer than LLDPEgMA for the HDPE/Nylon 6 blend system. In Chapter Four, multilayer films comprising polystyrene (PS)/polymethyl methacrylate (PMMA) and PS/polycaprolactone (PCL) alternating nanolayers with varied layer thickness were fabricated by multilayer coextrusion. The continuous layers started to break up into nanosheets and nanodroplets during the coextrusion process when the nominal layer thickness decreased to between 30 nm and 40 nm. Further decrease of the nominal layer thickness of PMMA and PCL resulted in less nanosheets and more nanodroplets. In Chapter Five, high oxygen barrier film/foams containing alternating ethylene-vinyl alcohol copolymer (EVOH) film layers and low-density polyethylene (LDPE) foam layers were innovated. The film/foams having low density and good oxygen barrier properties could be mechanically shaped into food packaging materials at room temperature.

This book was released on 2009-09-18 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structure formation in crystallizing polymers, as occurring during processing, has not been treated so far in a coherent form. This fact explains, why this monograph is written as the ?rst book devoted to this subject. A quarter of a century ago the underdevelopment of this subject was obvious. Trial and error dominated. In fact, other apposite subjects as polymer melt rheology or heat transfer, had reached high levels. A great number of books has been devoted to them. Mold ?lling of amorphous polymers and the solidi?cation of these polymers by vitri?cation can nowadays be simulated numerically with a high degree of accuracy. In the solidi?ed sample even residual stresses and corresponding birefringence effects can accurately be 1 calculated . However, semicrystalline polymers, which form the majority of industrial po- mers, have been excluded from these considerations for good reasons. In fact, great uncertainties existed about the formation of quality determining crystalline str- tures. In particular, polyole?ns suffered from this shortcoming. In 1983 this fact instigated the polymer research group at the Johannes Kepler University in Linz to start with pertinent activities. The urgency of this kind of studies becomes evident, if advantages and hitches of these polymers are considered. 1. Versatility of processing: Injection molding into a great variety of shapes and sizes, from thin walled beakers to garden chairs, not to forget pipe and pro?le extrusion, cable coating, ?ber spinning, ?lm blowing. 2. Product qualities: Ductility, low density, good electric insulation, corrosion resistance, surface quality.

Available in PDF, EPUB and Kindle. Book excerpt: From the Authors Introduction Diffusion is one of the few manageable nonequilibrium pro- cesses during which matter is transported through a system. Traditionally, diffusion is studied in physical chemistry; however, the fundamental understanding of diffusion processes is not possible without involving statistical physics. Diffusion in disordered systems, such as in polymers, has sometimes unexpected features, the nature of which has not yet been determined. Since modern technology involves more and more complex materials which rely on a subtle balance of microscopic effects, the understanding of diffusion processes in these materials is of paramount importance from the practical point of view. A renewed interest in the basic principles of diffusion is a direct result of new experimental data. This was a contributing factor in the preparation of this text. In the first chapter, the phenomenological thermodynamic basics of diffusion is reviewed, and the diffusion equation is derived from the principles of irreversible thermodynamics. The basic mathematical apparatus for solving diffusion equations is reviewed in the second chapter. The third chapter deals mainly with the vast amount of experimental data dealing with diffusion in polymers. . . . A reader interested in particular polymeric systems can use the . . . material as a useful introduction. The last chapter contains basic information concerning random walks and their application to the diffusion in disordered systems. The theory of random walks is widely used in polymer physics where it is usually combined with statistical mechanics to formulate various models of polymeric systems. Finally, useful mathematical formulas and references to the original sources of some mathematical methods are [provided] in the appendices. Some physical constants associated with several polymer solvent systems are also presented.

Download or read book Polymer Blends Volume 1 written by Donald R Paul and published by Elsevier. This book was released on 2012-12-02 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer Blends, Volume 1 highlights the importance of polymer blends as a major new branch of macromolecular science. Topics range from polymer-polymer compatibility and the statistical thermodynamics of polymer blends to the phase separation behavior of polymer-polymer mixtures, transport phenomena in polymer blends, and mechanical properties of multiphase polymer blends. The optical behavior, solid state transition behavior, and rheology of polymer blends are also discussed. This book is organized into 10 chapters and begins with an overview of polymer blends, with emphasis on terminology and the effect of molecular weight on the thermodynamics of polymer blends as well as phase equilibria and transitions. The discussion then turns to the miscibility of homopolymers and copolymers, in bulk and in solution, from the experimental and theoretical viewpoints. The chapters that follow explore the statistical thermodynamics of polymer blends, paying particular attention to the Flory and lattice fluid theories, along with the phase relationship in polymer mixtures. The interfacial energy, structure, and adhesion between polymers in relation to the properties of polymer blends are considered. The final chapter examines the phenomena of low molecular weight penetrant transport. Currently accepted models for unsteady-state and steady-state permeation of polymeric materials are presented. A discussion of unsteady-state absorption and desorption behavior observed in a variety of polymer blends complements the treatment of permeation behavior. This book is intended to provide academic and industrial research scientists and technologists with a broad background in current principles and practice concerning mixed polymer systems.
