Book Description
Chemical modification of polymers by reactive modifiers is no longer an academic curiosity but a commercial reality that has delivered a diverse range of speciality materials for niche markets: reactively grafted styrenic alloys, maleated polyolefins, super-tough nylons, silane modified and moisture-cured polyolefins, and thermoplastic elastomers, are but few exam ples of commercial successes. Although the approach of reactive modification of polymers has been largely achieved either in solution or in the solid state (through in situ reactions in polymer melts), it is the latter route that has attracted most attention in the last two decades owing to its flexibility and cost-effective ness. This route, referred to as reactive processing, focuses on the use of suitable reactive modifier(s) and the adoption of conventional polymer processing machinery, an extruder or a mixer, as a chemical reactor, to perform in situ targeted reactions for chemical modification of preformed polymers. This relatively simple, though scientifically highly challenging, approach to reactive modification offers unique opportunities in exploiting various reactive modifiers for the purpose of altering and transforming in a controlled manner the properties of preformed commercial polymers into new/speciality materials with tailor-made properties and custom-designed performance for target applications. Such an economically attractive route constitutes a radical diversion away from the traditional practices of manufacturing new polymers from monomers which involves massive in vestments in sophisticated technologies and chemical plants.

Book Description
Loaded with practical knowledge, Reactive Polymers Fundamentals and Applications: A Concise Guide to Industrial Polymers comprehensively presents the state-of-art of methods and materials for the formulation of polymeric resins. It is an indispensable tool for chemists, engineers, and manufacturers who use, formulate, and cure raw materials into final products. The text focuses on the chemical modification of properties during the final stage of part fabrication from plastics. Newer applications range from the small scale, such as dental fillings, to industrial processes for batch fabrication. The book covers resin groups in major use in industry and under active research and development.

Book Description
Reactive Polymers: Fundamentals and Applications: A Concise Guide to Industrial Polymers, Third Edition introduces engineers and scientists to a range of reactive polymers and then details their applications and performance benefits. Basic principles and industrial processes are described for each class of reactive resin (thermoset), as well as additives, the curing process, applications and uses. The initial chapters are devoted to individual resin types (e.g., epoxides, cyanacrylates), followed by more general chapters on topics such as reactive extrusion and dental applications. Injection molding of reactive polymers, radiation curing, thermosetting elastomers, and reactive extrusion equipment are covered as well. The use of reactive polymers enables manufacturers to make chemical changes at a late stage in the production process, which, in turn, cause changes in performance and properties. Material selection and control of the reaction are essential to achieve optimal performance. Material new to this edition includes the most recent developments, applications and commercial products for each chemical class of thermosets, as well as sections on fabrication methods, reactive biopolymers, recycling of reactive polymers and case studies. Covers the basics and most recent developments, including reactive biopolymers, recycling of reactive polymers, nanocomposites and fluorosilicones Offers an indispensable guide for engineers and advanced students alike Provides extensive literature and patent review Reflects a thorough review of all literature published in this area since 2014 Features revised and updated chapters to reflect the latest research in reactive polymers

Book Description
The book provides a unique collection of 15 contributions by 15 internationally recognized scientists performing intensive research activity on the preparation and characterization of complex and multiphase materials based on macromolecules as well as on the evaluation and simulation of structure/properties relations. The topic is assuming a general increasing importance as providing a highly sustainable and modern approach to the present and future development of the important area of materials science and technology. The scientific route along the successive contributions goes from the controlled preparation of functional MM both by innovative polymerization reactions and preformed polymers modification (intramacromolecular complexity), to their combination with other MMs and materials to give blends and composites where new properties are conveniently achieved by morphologic complexity. The synergic behaviour of the different components in these last is obtained by reactive processing producing the necessary interfacial adhesion. Even if most examples deal with man-made MMs, biopolymers are also included. The various chapters provide in most cases an exhaustive fundamental description assisted by an up- to-date and broad list of relevant references The book is therefore an excellent informative and formative instrument for those involved in complex materials preparation and application in research and industry.
