Photoinitiating systems for polymerization reactions are largely encountered in a variety of traditional and high-tech sectors, such as radiation curing, (laser) imaging, (micro)electronics, optics, and medicine.
This book extensively covers radical and nonradical photoinitiating systems and is divided into four parts:
* Basic principles in photopolymerization reactions

* Nonradical photoinitiating systems
* Reactivity of the photoinitiating system
The four parts present the basic concepts of photopolymerization reactions, review all of the available photoinitiating systems and deliver a
thorough description of the encountered mechanisms. A large amount of experimental and theoretical data has been collected herein. This
book allows the reader to gain a clear understanding by providing a general discussion of the photochemistry and chemistry involved.
The most recent and exciting developments, as well as the promising prospects for new applications, are outlined.

Polymer nanocomposites have revolutionised material performance, most notably in the plastics, automotive and aerospace industries. However, in order to be commercially viable, many of these materials must withstand high temperatures. In this book, leaders in the field outline the mechanisms behind the generation of suitable polymer systems, pulling together recent research to provide a unified and up-to-date assessment of recent technological advancements. The text is divided into two clear sections, introducing the reader to the two most important requirements for this material type: thermal stability and flame retardancy. Special attention is paid to practical examples, walking the reader through the numerous commercial applications of thermally stable and flame retardant nanocomposites. With a strong focus on placing theory within commercial context, this unique volume will appeal to practitioners as well as researchers.

When many polymers are heated they transform directly into carbons, without passing through an intermediate liquid paste. Such carbons are termed polymetric carbons. Phenolic resins yield an isotropic impervious black glassy carbon which is hard enough to scratch window glass and has interesting electronic properties. polyacrylonitrile fibres yield carbon fibre with enormous stiffness and strength. Combinations of the two produce the strongest carbon material (carbon-fibre-reinforced carbon). Carbon-fibre-reinforced plastics are revolutionary low density-high-stiffness materials. This 1976 book brings together data from the authors' work to describe the manufacture of polymetric carbons. It provides a description of physical, mechanical and chemical properties which are related as closely as possible to the revealed structure. Emphasis is placed on the more interesting aspects, such as development of high-strength, high-stiffness material, the semi-conducting behaviour of intermediate materials and the absorption of gases in the more open structure of absorbent chracoals.

This book details original, theoretical, and important experimental results that use non-routine methodologies often unfamiliar to most readers. It also includes papers on novel applications of more familiar experimental techniques and analyses of composite problems. The book provides comprehensive coverage on the latest developments of research in the ever-expanding area of composite materials and their applications to broad scientific fields spanning physics, chemistry, biology, materials, and more.

This book presents the analysis of up-to-date techniques used for the determination of acid-base properties in view of their applicability to examination of solid organic and inorganic surfaces. The studies have been carried out by the authors since 1993, showing experimental data on surface properties of more than 150 polymers, such as carbocatenary and heterochain polymers, copolymers and their blends, as well as different epoxy and rubber compositions used in adhesive joints. The adhesive ability of metal-polymer systems based on epoxy compositions, polyolefins, and rubbers was studied as a function of absolute difference in acid-base properties of adhesive and adherends, and the possibility to predict adhesive interaction on this basis was experimentally verified. The book shows the important role that acid-base interactions play in establishing interfacial adhesive-adherent contact and outlines practical recommendations regarding parameters of quantitative estimation of acid-base surface properties that implies the relationship with adhesive ability in polymer-metal systems. Creating polymeric materials with greater strength characteristics when in contact with metals is the most important problem when adhesive joints are designed. The authors obtained experimental data for thermodynamic and acid-base properties of about 200 organic and inorganic surfaces that find a wide practical application. These results may be used as a reference source to predict the adhesive ability of different coating systems. The possibility to predict adhesive interaction of adhesive with adherend, taking into account the absolute difference in their acidity and basicity, was verified experimentally.

Thermosetting plastics are a distinct category of plastics whose high performance, durability and reliability at high temperatures makes them suitable for specialty applications ranging from automotive and aerospace through to electronic packaging and consumer products (your melamine kitchen worktop is a thermoset resin ). Recent developments in thermoset plastics technology and processes has broadened their use exponentially over recent years, and these developments continue: in November 2011, French scientists created a new lightweight thermoset that is as strong and stable as previous materials yet can be easily reworked and reshaped when heated which makes it unique amongst thermosets and allows for repair and recycling.

The Handbook of Thermoset Plastics, now in its 3rd edition, provides a comprehensive survey of the chemical processes, manufacturing techniques and design properties of each polymer, along with their applications. Written by a team of highly experienced practitioners, the practical implications of using thermoset plastics are presented - both their strengths and weaknesses. The data and descriptions presented here enable engineers, scientists and technicians to form judgments and take action on the basis of informed analysis. The aim of the book is to help the reader to make the right decision and take the correct action - avoiding the pitfalls the authors experience has uncovered.

This book was first published in 2007. Polymers exhibit a range of physical characteristics, from rubber-like elasticity to the glassy state. These particular properties are controlled at the molecular level by the mobility of the structural constituents. Remarkable changes in mobility can be witnessed with temperature, over narrow, well defined regions, termed relaxation processes. This is an important, unique phenomenon controlling polymer transition behaviour and is described here at an introductory level. The important types of relaxation processes from amorphous to crystalline polymers and polymeric miscible blends are covered, in conjunction with the broad spectrum of experimental methods used to study them in 2007. In-depth discussion of molecular level interpretation, including atomistic level computer simulations and applications to molecular mechanism elucidation, are discussed. The result is a self-contained approach to polymeric interpretation suitable for researchers in materials science, physics and chemistry interested in the relaxation processes of polymeric systems.
