This book was released on 2023-01-27 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural polymers have always been used in medicine. However, the development of synthetic polymers for use in medicine has occurred only in the last few decades. The successful applications of these synthetic polymers in medicine depend mainly on their physico-chemical and special characteristics such as biological compatibility with tissues, stability, durability and elasticity. This book deals mainly with the kinetic and structural aspects which are essential for the realization of these characteristics. The authors have examined in detail the processes of diffusion, chemical and biological diintegration, changes in various structural levels induced by chemical and biological media, and the problems of simultaneous influence of these media and mechanical strains on polymers used in medicine.

Download or read book Biodamage and Biodegradation of Polymeric Materials written by Elena L Pekhtasheva and published by Smithers Rapra. This book was released on 2012-08-31 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The issue of biodamages comprises a wide range of scientific and practical tasks associated with protection of raw materials and products against damage by bacteria, fungi, insects and rodents during long-term storage, production, transportation and operation. The biodegradation is used for degradation and utilization of worn-out materials and articles. This research is urgent for ecology and the struggle against environmental contamination. The biodamage problem is both scientifically complex and practically diverse. Scientifically, it is based on the knowledge of material science, biology and chemistry.The first objective of this book is to provide detailed information on the three interrelated parts: bacteria and fungi (the source of biodamages); insects and rodents (materials and products depredators); and materials and products damaged by living organisms. The most modern data on morphology and physiology of biodegrading microorganisms are presented. The second objective of this book is to provide the reader with a systematisation of biological degradation on both natural and synthetic materials and products (plastics, textile, fibres, leather and fur, wood and so on). Problems of utilisation of polymeric wastes using microorganisms are discussed and main protection methods and technology for raw materials and semi-products against biodamages are shown. Practical recommendation for struggle against biodamage of materials by insects (moth, leather beetles, wood-fretters, cockroaches and termites) and rodents (mice and rats) are given.Since 1960 the biodamage problem received the official status as a large international and practical direction at the junction of sciences and practice of mankind and pooling efforts of various specialists. The final objective of this book is to illustrate that the problem of biodamages is very real today because it is relevant to many aspects of our everyday lives.This volume is intended to be a practical guide on biodamage and biodegradation of polymeric materials and a quick reference to students and researchers from academia and the industry.

Download or read book The Concept of Micellar Sponge Nanophases in Chemical Physics of Polymers written by Yuri Arsenovich Mikheev and published by CRC Press. This book was released on 2004-04-01 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The monograph is intended for elucidation of the novel trend in chemical physics regarding the polymer non-crystalline phase. It stresses the physical phenomena affecting the kinetics and mechanism of chemical reactions proceeding in the non-crystalline polymer matrix (NCPM). NCPM is depicted in terms of a supramolecular (carcass-micellar) model. The model is thought to reflect heterophase packing of polymeric chains, which co-operate as a molecular-chain sponge. The NCPM model presented is proved for adequate description of principal structure-physical phenomena to elaborate the scheme of structural-kinetic modeling of chemical reactions in bulky polymers. Structure-physical phenomena elucidated in the monograph are: - peculiarities of polymer plasticization and polymer blending with liquids; - structural and thermodynamic aspects of sorption of low molecular species; - properties of ESR (spin) probes and optical (molecular) probes; - features of water absorbed by polymers; - mechanical and thermal effects generated by the molecular-chain sponge; - supramolecular aspects of NCPM chemical physics. This monograph includes the structural-kinetic modeling of complex polymer chemical reactions. It deals with the problem of mechanism and kinetics of free radical chain reactions using thermal and photochemical model reactions of dibenzoyl peroxide with glassy-like polymers (cellulose triacetate, polycarbonate, polystyrene, polyamide PA-548), viscoelastic polymers (atactic polypropylene, polyamide PA-548, polyethylene, polyisobutylene, melted poly(ethylene oxide), and isotactic polypropylene. In all cases, the supramolecular heterophase mechanism of the processes, which was unknown for homogeneous systems, was proved. Furthermore, heterophase mechanisms of photochemical reaction between naphthalene and cellulose triacetate and photolysis of poly(methyl methacrylate) proceeding as a photochain reaction are indicated.

Download or read book Thermal Oxidation of Polymer Blends written by Lyudmila Shibryaeva and published by CRC Press. This book was released on 2006-06-08 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: To identify the specific features of the kinetics of oxidation of polymer mixtures, determine the key structural elements, and create a model that can describe the mechanism of thermal oxidation of polymer mixtures, it is necessary to determine the relation between the initial structure of a polymer mixture, structural rearrangements associated with oxidation and the kinetics of the process. The aim of this book is to elucidate the complicated problem concerning the connection between the structure and mechanism of oxidation of heterogeneous and heterophase polymer systems. The material presented in this book concerns the specific features of the kinetics of oxidation and those of the structure of polymer systems. The book deals with an analysis of the key factors that can affect principally the mechanism of thermal oxidation of polymer mixtures, determines the role of the phase morphology, structure of components, and the interface layer (or boundary) in the kinetics of oxidation of heterophase system by an example of mixtures of polyolefines. Along with the kinetics of oxidation of heterophase systems, problems of investigation of their structural parameters in the oxidized state are considered. With this aim, the material presented in the book concerns not only the mechanism of oxidation of polymer mixtures but also homopolymers of diverse morphology and model systems.
