Green chemistry is the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. Green polymer chemistry is an extension of green chemistry to polymer science and engineering. Developments in this area have been stimulated by health and environmental concerns, interest in sustainability, desire to decrease the dependence on petroleum, and opportunities to design and produce "green" products and processes. Major advances include new uses of biobased feedstock, green reactions, green processing methodologies, and green polymeric products. A current feature of green polymer chemistry is that it is both global and multidisciplinary. Thus, publications in this field are spread out over different journals in different countries. Moreover, a successful research effort may involve collaborations of people in various disciplines, such as organic chemistry, polymer chemistry, material science, chemical engineering, biochemistry, molecular biology, microbiology, enzymology, toxicology, environmental science, and analytical chemistry. This book combines the major interdisciplinary research in this field and is targeted for scientists, engineers, and students, who are involved or interested in green polymer chemistry. These may include chemists, biochemists, material scientists, chemical engineers, microbiologists, molecular biologists, enzymologists, toxicologists, environmental scientists, and analytical chemists. It can be a textbook for a course on green chemistry and also a reference book for people who need information on specific topics involving biocatalysis and biobased materials.

Im Toxic Substances Control Act (ToSCA) von 1984 wurde festgelegt, unter welchen Bedingungen Polymere von den toxikologischen Anforderungen befreit sind, die üblicherweise an neue Verbindungen gestellt werden. Diese Richtlinien wurden 1995 neu gefaßt. "Designing Safer Polymers" will dem Hersteller oder Importeur solcher Chemikalien im wesentlichen folgende Fragen beantworten: Ist der von ihm betrachtete Stoff ein Polymer im Sinne der Ausnahmeregelung? Erfüllt der Stoff die Bedingungen für eine Befreiung gemäß ToSCA? Welche Faktoren stehen der Befreiung gegebenenfalls im Wege? Ein informatives Handbuch für die Praxis! (01/01)

This book comprehensively covers researches on enzymatic polymerization and related enzymatic approaches to produce well-defined polymers, which is valuable and promising for conducting green polymer chemistry. It consists of twelve chapters, including the following topics: The three classes of enzymes, oxidoreductases, transferases and hydrolases, have been employed as catalysts for enzymatic polymerization and modification; Well-defined polysaccharides are produced by enzymatic polymerization catalyzed by hydrolases and transferases; Hydrolase-catalyzed polycondensation and ring-opening polymerization are disclosed to produce a variety of polyesters; Polyesters are synthesized by in-vivo acyltransferase catalysis produced by microorganisms; Enzymatic polymerization catalyzed by appropriate enzymes also produces polypeptides and other polymers; Poly(aromatic)s are obtained by enzymatic polymerization catalyzed by oxidoreductases and their model complexes; Such enzymes also induce oxidative polymerization of vinyl monomers; Enzymatic modification of polymers is achieved to produce functionalized polymeric materials; The enzymatic polymerization is a green process with non-toxic catalysts, high catalyst efficiency, green solvents and renewable starting materials, and minimal by-products; Moreover, renewable resources like biomass are potentially employed as a starting substrate, producing useful polymeric materials. This book is not only educative to young polymer chemists like graduate students but also suggestive to industrial researchers, showing the importance of the future direction of polymer synthesis for maintaining a sustainable society.

Green polymer chemistry is now a global pursuit and comprises diverse disciplines, such as organic synthesis, polymer chemistry, material science, microbiology, molecular biology, catalysis, enzymology, environmental science, analytical chemistry, and chemical engineering. This field is equally active in the United States as well as Europe and Asia. Researchers, students, and people new to this field value a forum to meet and share ideas; this can take the form of a symposium dedicated to this field, or a special book that features the latest work done by leading practitioners. "Green Polymer Chemistry: Biobased Materials and Biocatalysis" is a symposium series put on by the American Chemical Society that has been very successful and serves to bring together a community of scientists with different backgrounds but with common research interests. In the August 2017 symposium in Washington, D.C., there were a total of 84 presentations and 16 posters (one of the largest symposia in the meeting). The symposium was structured into 10 sessions: -Bio-Based Materials: Industrial Perspectives -Developments in Biocatalysts -Green Biocatalytic Transformations -Chemical Catalytic Routes to Bio-Based Materials -New Reaction Strategies and Materials -Polysaccharide-Based Materials -Plant Oils and Ferulate-Based Materials -Bio-Based Thermosetting Resins -Therapeutics and Opto-Electronics -Further Applications of Bio-Based Materials Many of the leading researchers in this field accepted the invitation to speak, and they reported exciting findings in various areas, including new bio-based source materials, green conversion methods, new or improved processing methodologies, and green polymer-related products. For convenience, this book is organized into seven sections: novel bioengineered approaches; new enzymatic methodologies; new materials based on polysaccharides; bio-related polyesters, polyamides, and polyurethanes; bio-based phenolics and composites; bio-based monomers and resulting products; and bio-based solvents and additives.

Polymer science faces the challenge of meeting growing market demand for polymers whilst achieving sustainability through environmentally friendly processes. Microwave heating has emerged as a greener technique that accelerates a variety of chemical reactions, including polymerization. Microwave-assisted reactions can be cleaner and more rapid and economic analyses suggest that the cost of curing polymers may be reduced by switching over to the use of microwaves. This book provides comprehensive coverage of microwave-assisted polymerization. The first chapter introduces readers to the theory behind the accelerating effects of microwaves on chemical reactions and covers the types of commercial microwave reactors being used for synthesis and processing of polymers that are available on the market. Subsequent chapters are organised by type of reaction, including radical homo and co-polymerizations, step growth polymerization and peptide synthesis. Importantly, analysis of processes and product properties in comparison with conventional methods is also detailed. This book will be a valuable resource for green chemists and polymer scientists and engineers who want to develop sustainable processes.
