Because of the sheer size and scope of the plastics industry, the title Developments in Plastics Technology now covers an incredibly wide range of subjects or topics. No single volume can survey the whole field in any depth and what follows is, therefore, a series of chapters on selected topics. The topics were selected by us, the editors, because of their immediate relevance to the plastics industry. When one considers the advancements of the plastics processing machinery (in terms of its speed of operation and conciseness of control), it was felt that several chapters should be included which related to the types of control systems used and the correct usage of hydraulics. The importance of using cellular, rubber-modified and engineering-type plastics has had a major impact on the plastics industry and therefore a chapter on each of these subjects has been included. The two remaining chapters are on the characterisation and behaviour of polymer structures, both subjects again being of current academic or industrial interest. Each of the contributions was written by a specialist in that field and to them all, we, the editors, extend our heartfelt thanks, as writing a contribution for a book such as this, while doing a full-time job, is no easy task.

From the late-1960's, perfluorosulfonic acid (PFSAs) ionomers have dominated the PEM fuel cell industry as the membrane material of choice. The "gold standard' amongst the many variations that exist today has been, and to a great extent still is, DuPont's Nafion (R) family of materials. However, there is significant concern in the industry that these materials will not meet the cost, performance, and durability requirementsnecessary to drive commercialization in key market segments - es- cially automotive. Indeed, Honda has already put fuel cell vehicles in the hands of real end users that have home-grown fuel cell stack technology incorporating hydrocarbon-based ionomers. "Polymer Membranes in Fuel Cells" takes an in-depth look at the new chem- tries and membrane technologies that have been developed over the years to address the concerns associated with the materials currently in use. Unlike the PFSAs, which were originally developed for the chlor-alkali industry, the more recent hydrocarbon and composite materials have been developed to meet the specific requirements of PEM Fuel Cells. Having said this, most of the work has been based on derivatives of known polymers, such as poly(ether-ether ketones), to ensure that the critical requirement of low cost is met. More aggressive operational requi- ments have also spurred the development on new materials; for example, the need for operation at higher temperature under low relative humidity has spawned the creation of a plethora of new polymers with potential application in PEM Fuel Cells.

This book is derived from a recent project sponsored by the Polymer Engineering Directorate of the SERC and carried out at the University of Lancaster under the joint auspices of the Departments of Chemistry and Engineering. The project set out to provide a novel type of teaching material for introducing polymers and their uses to students, especially of engineering. Case studies of real examples of polymers at work are used, so the student or teacher can start with a successful and well-designed product and work backwards to its origins in the market, in design and material selection and in the manufacturing process. The philosophy is that such an approach captures interest right at the start by means of a real example and then retains it because of the relevance of the technical explanation. This after all is what most of us do habitually; we turn to examples to make our point. The hope is that subject matter with a somewhat notorious reputation among engineers, such as aspects of polymer chemistry and the non-linear behaviour of polymers under mechanical loading will be fairly painlessly absorbed through the context of the examples. Each study becomes a separate chapter in the book. The original studies, and hence the present chapters, vary in length because different topics demanded different approaches. No attempt has been made to alter this, or to adopt a standardized format because to have done so would have interfered with the vitality of the original work.

This volume includes reviews on tackling polymer characterisation problems and on developing specific characterisation techniques. The first two chapters and the last chapter describe progress in providing character isation information for polymers containing long-chain branching, for polymer blends, and for polymers having preferred orientation. The remaining chapters review progress in individual techniques, showing with examples the characterisation results which may be obtained. It is recognised that the degree of chain branching which can evolve in some polymerisation processes can have a marked effect on the flow properties of a polymer, and therefore on polymer processing behaviour. In the first chapter the characterisation of long-chain branching from measurements of the molecular size and molar mass of a polymer in dilute solution is outlined. It is indicated that a complete characterisation of branching requires the combined use of several techniques, emphasising in particular recent developments involving gel permeation chromatography. Thermal analysis and infrared spectroscopy are widely used techniques in polymer characterisation. Both techniques can provide, very quickly, significant results with readily available instrumentation. This is illustrated by the review of the characterisation of polymer blends by thermal analysis in Chapter 2. An assessment of blend morphology, which influences the behaviour of a material consisting of two or more polymers, is presented in terms of transition temperatures. Conventional infrared spectroscopy involves dispersive spectrometers which do not always provide accurate information on composition and structure for complex polymeric materials."

The last six years have seen a great shift in plastics recycling from the mechanical recycling of the early nineties towards a more integrated approach in which feedstock recycling and the recovery of incineration energy is encouraged. Based on extensive research of the international recycling industry, this book describes technological advances in polymer recycling from the sorting stage through to recycling processes and end-use applications; provides an overview of state-of-the-art recycling techniques with current and potential applications and draws together and consolidates literature in this rapidly growing field. Due to widespread growing concern over the contribution of plastics to environmental pollution, a book which does all of the above is long overdue. In the US and Europe the recycling of polymers is a major political issue and has become an expanding commercial activity. Dr. Scheirs places significant emphasis on the recycling of automobile tyres, polyurethane foams, carpets, engineering plastics and fibre-reinforced composites, all of which had been previously thought to be hard to recycle.

Much data has been collected from experiments on the kinetios of radical reactions in different solids, but to date, this has not been presented in book format in a thorough and comprehensive way. This book makes the experimental data accessible for all chemists involved in these reactions. Various models of the tunnel atom transfer are analyzed in order to explain the kinetic isotope effect in solid phase reactions and photoinitiated radical reactions are inspected for the kinetic non-equivalence of particles and factors affecting their reactivity. Topics covered include:
* kinetic description of reactions with dispersion particles in reactivity
* the influence of space-orientation factors on reactivity in cage reactions
* the influence of molecular dynamics on the kinetics of elementary reactions
* the effect of structural-physical modification on kinetics of cage radical reactions
