Multicomponent Transport in Polymer Systems for Controlled Release


Book Description

This book addresses the general aspects of current knowledge of multicomponent transport in hydrophylic and moderately hydrophylic polymers. The first part of the book presents the physical and mathematical models which have been developed in order to predict the behavior of systems consisting of polymer, water and low-molecular solutes. The second half addresses different transport devices for controlled delivery and how the principles reported in the first part could be applied to the regulations of kinetics and the rate of transport of water and solutes. Major applications of polymer systems for controlled release in medicine, agriculture, and in industry are also described.

Physical Properties of Polymers


Book Description

New polymeric substances and materials with new, often unusual properties arise frequently. This volume presents a problem in determining the physical properties of polymers and thus makes it difficult to tackle the question of the synthesis of polymers with desired properties. The author has approached this problem in a semi-empirical manner, which like van Krevelen's empirical method is based on the principle of increment and deriving calculations from it, but in Askadskii's approach each equation for the calculation of properties is physically based, and its parameters are connected with characteristics of atoms (Van-der-Waals volume, dispersonic interaction) which compose the reoccurring unit of polymer, as well as with characteristics of energy of intermolecular interaction. Particular attention is paid to the relaxation of properties of polymers, which determine the mechanical serviceability of materials.




Electrophysical Phenomena in the Tribology of Polymers


Book Description

Numerous practical problems connected to triboelectric phenomena remain unsolved in both the fabrication and behavior of polymer threads and fabrics in a variety of industrial articles. Using the results of unique experiments carried out in the countries of the former Soviet Union, this volume fills a gap in the science of tribology, presenting fundamental information on the nature of physical and chemical processes governing and accompanying tribodeformation and tribodisintegration of polymers. Details on electrophysical phenomena such as contact electrification and emergence of the electret state in polymer materials are also provided.




Fast Polymerization Processes


Book Description

Fast Polymerization Processes presents fundamental results of investigation in the field of fast polymerization processes. A practical approach to the studying and modeling of polymerization processes is highlighted, taking into consideration the influence of such issues as the reactants' concentration, flow velocities, densities, heat conductivities, and hydrodynamics parameters. Particular attention is devoted to an in-depth description of previously unknown rules which are characteristic of fast polymerization processes.

Handbook of Plastic Films


Book Description

Plastic films are high-performance materials which play an essential part in modern life. The plastics films industry uses state-of-the-art manufacturing processes and is continuously seeking out new technologies to improve its performance. The understanding of the nature of plastic films, their production techniques, applications and their characterisation is essential for producing new types of plastic films. This handbook has been written to discuss the production and main uses of plastic films. Plastic films are high-performance materials which play an essential part in modern life. Plastic films are mostly used in packaging applications but as will be seen from this book they are also used in the agricultural, medical and engineering fields.

Physico-Chemical Principles for Processing of Oligomeric Blends


Book Description

Covers the current state of theoretical and experimental studies of oligomeric mixed systems from the physico-chemical standpoint and provides a technologist with the means for the quantitative approach to preparing liquid oligomeric compositions and choosing proper operating conditions for their processing into materials and articles. Recommendations are given on the practical use of found physico-patterns as well as the physico-chemical analysis of the effect of the composition ingredients on the final properties.
