DOWNLOAD EBOOKNatural 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. Researchers in the field of polymer physics and chemistry, as well as those who are working with applications of polymers in medicine and biology should find this book useful.

DOWNLOAD EBOOKThe 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 EBOOKThe 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 EBOOKThis 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.

DOWNLOAD EBOOKThis book considers general aspects of the theory of polymers applied in optics. The main factors affecting the light loss in polymeric wave beam guides (PG) are discussed, and the mechanism of light loss in PG is analysed. Polymers applied in fiber optics are classified with reference to methods of fabrication and purification of the materials. Technological aspects of material fabrication are considered together with kinetic aspects of polymerisation. Updated information on polymerisation kinetics of MMA and styrene, and copolymerisation of these monomers with each other is reported. Other topics discussed in the book are heterogeneity of optic copolymers, association between structure and reactivity of monomers, other properties of optic copolymers, and areas of their commercial application. This volume will be of value and interest to anyone working in the field of optic polymers, both in academia and industry.
