Book Description
Twenty-one papers collected here report on the latest work in polymer ageing, looking at aspects including the ageing of polyester resin under moisture action, kinetic peculiarities of synthesis of Adamantan- containing polyamidoacids and polyimides, the influence of intensive mechanical treatment on decomposition of barium peroxide, and ecological aspects of manufacture and application of highly pure liquid substances. Biodegradable blends of starch and cellulose derivatives, the quantum chemical calculation of components of biosynthesis of adrenaline, low combustible poly(vinyl chloride) compositions with mixtures of plasticiSers, and inhibited oxidation of polypropylene melt are some other topics discussed.

Book Description
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.

Book Description
Accelerated Aging: Photochemical and Thermal Aspects represents the culmination of more than 40 years of research by noted scientist Robert L. Feller. The book focuses on the long-term performance of materials such as wool, dyes, and organic compounds; their resistance to change when exposed to environmental factors such as oxygen, ozone, moisture, heat, and light; and their physical durability with handling and use over time. Processes of deterioration are discussed based on speeded-up laboratory studies designed to clarify the chemical reactions involved and their physical consequences.

Book Description
Chemometrics is the chemical discipline that uses mathematical, statistical and other methods employing formal logic: to design or select optimal measurement procedures and experiments, and -- to provide maximum relevant chemical information by analysing chemical data. Being conceived as a branch of analytical chemistry, chemometrics now is a general approach. It extracts relevant information out of measured data, regardless of their origin: chemical, physical, biological, etc. Chemometrics has been applied in different areas, and most successfully in multivariate calibration, pattern recognition, classification and discriminant analysis, multivariate modelling, and monitoring of processes. The main chemometric principle is a concept of hidden data structures that can be found using methods of multivariate data analysis. These are the well-known statistic tools such as partial least squares (PLS), soft independent modelling of class analogy (SIMCA), principal-component regression (PCR), wavelet analysis, and many others. Current activities of chemometricians fall into two main categories: (1) development of new methods for manipulating multivariate data and (2) new applications of the known chemometric techniques in different areas such as environment control, food industry, agriculture, medicine, and engineering.

Book Description
This collection examines the influence of liquid and solid states during radical, ionic, and molecular reactions, specifically how cage effect, diffusion hindrance, donor-acceptor interaction, electrostatic interaction, dispersion forces and other factors affect the rates, mechanism, and direction of chemical reactions. Topics of the 11 papers include spherical hydrogel particles for endovascular embolisation, the synthesis and thermal degradation of phenolic resins, mono-molecular chain termination in dimethacrylate postpolymerisation, and calculating the effect of chain deformation on macromolecule scission. Most of the researchers work in Russia.
