Moulded particle (bead) foam products are nowadays ubiquitous, in packaging and construction, from drinking cups to motorway foundations. The industry which started with Expanded Polystyrene (EPS) has grown spectacularly and now also includes Expanded Polypropylene and Expanded Polyethylene, and its technology and machinery has become so specialised that it is seen as an almost isolated branch of the plastics industry. The first part of this update summarises the present status of particle foam technology and how specific challenges have already driven its development. This includes the potent

Styrenic polymers are among the economically most important plastics. They combine benign processing with a large variety of product properties - from stiff and transparent to tough and durable. The fact that styrene can be polymerized by different reaction mechanisms (radical, ionic and metal catalyzed) makes this line of products unique in regards to the variety of its properties and applications. The primary objective of this book is to provide a detailed understanding of structure and property relationships of styrenic polymers, and their specific use in various applications. By understand

Styrenic copolymers are engineering thermoplastics. The most important are styrene-acrylonitrile copolymer (SAN) and acrylonitrile-butadiene-styrene terpolymer (ABS). Other monomers can also be used with styrene including methyl methacrylate and maleic anhydride. Blends of styrenic copolymers with other thermoplastics are also becoming established in the market place, the most common are blends of ABS with polycarbonate or polyamide. The main market sectors for these materials are automotive and transport, electrical and electronics, and information technology applications. In Europe alone the

This reprint is a compilation of nine papers published in Processes, in a Special Issue on “Modeling and Simulation of Polymerization Processes”. It aimed to address both new findings on basic topics and the modeling of the emerging aspects of product design and polymerization processes. It provides a nice view of the state of the art with regard to the modeling and simulation of polymerization processes. The use of well-established methods (e.g., the method of moments) and relatively more recent modeling approaches (e.g., Monte Carlo stochastic modeling) to describe polymerization processes of long-standing interest in industry (e.g., rubber emulsion polymerization) to polymerization systems of more modern interest (e.g., RDRP and plastic pyrolysis processes) are comprehensively covered in the papers contained in this reprint.

Elastomer materials are characterized by their high elongation and (entropy) elasticity, which makes them indispensable for widespread applications in various engineering and medical areas as well as consumer goods. This book focuses on the state-of-the-art of elastomers covering all aspects from their properties to applications. The development and testing of advanced elastomers is of particular interest. Attention is given to various aspects of elastomers, such as ever-increasing environmental concepts dealing with recyclability and reusability, incorporation of functional groups or additives to obtain novel functionality or bioelastomers, analytical description of mechanisms and structure relations of the fracture behavior of elastomers, and their external stimuli-responsive character. The scope of the book encompasses contributions at the frontier of science in polymer network synthesis, experimental and theoretical physics of polymer networks, and new structures and functionalities incorporated into elastomers leading to enhanced properties of crosslinked elastomeric materials, among others.

Additive manufacturing (AM) processes are gaining more and more attention from many industrial fields, mainly because they are revolutionizing the components’ designs and production lines. The complete industrialization of these processes has to be supported by the full understanding of correlation between AM building conditions and the final materials’ properties. Another critical aspect is that nowadays only a reduced number of materials processable by AM are available on the market. It is, therefore, fundamental to widen the materials’ portfolio, and to study and develop new materials that can take advantage of these unique building processes.

“Functional Polymer Solutions and Gels—Physics and Novel Applications” contains a broad range of articles in this vast field of polymer and soft matter science. It shows insight into the field by highlighting how sticky (non-covalent) chemical bonds can assemble a seemingly water-like liquid into a gel, how ionic liquids influence the gelation behavior of poly(N-Isopropylacrylamide) as well as how the molecular composition of functional copolymers is reflected in the temperature-responsiveness. These physics were augmented by theoretical works on drag-reduction. Also, drug-release – an improved control of how fast or dependent on an external factor – and antibacterial properties were the topic of several works. Biomedical applications on how cell growth can be influenced and how vessels in biological systems, e.g., blood vessels, can be improved by functional polymers were complemented with papers on tomography by using gels. On totally different lines, also the topic of how asphalt can be improved and how functional polymers can be used for the enrichment and removal of substances. These different papers are a good representation of the whole area of functional polymers.
