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)

Green toxicology is an integral part of green chemistry. One of the key goals of green chemistry is to design less toxic chemicals. Therefore, an understanding of toxicology and hazard assessment is important for any chemist working in green chemistry, but toxicology is rarely part of most chemists' education. As a consequence, chemists lack the toxicological lens necessary to view chemicals in order to design safer substitutions. This book seeks to fill that gap and demonstrate how a basic understanding of toxicology, as well as the tools of in silico and in vitro toxicology, can be an integral part of green chemistry. R&D chemists, product stewards, and toxicologists who work in the field of sustainability, can all benefit from integrating green toxicology principles into their work. Topics include in silico tools for hazard assessment, toxicity testing, and lifecycle considerations, this book aims to act as a bridge between green toxicologists and green chemists.
Covers the design or redesign of chemicals with the specific intent of making them safe for people and the environment. Explains how commercially useful substances of low toxicity can be designed and developed through careful forethought and strategic molecular modification. Describes how existing industrial chemicals that are toxic can be redesigned to be less toxic but retain their usefulness. Discusses how to merge the disciplines of toxicology and chemistry to design new, less toxic commercial chemicals or redesign existing toxic commercial chemicals to result in less toxic substitutes. Provides researchers, developers, and manufacturers of industrial chemicals with a reference source for designing safer chemicals.
Plastics & Sustainability clearly lays out the thorny and contentious issues that we encounter at the nexus of plastics and sustainability. The book serves as a practical guide for making sustainability decisions about how plastics are made and used, including current developments in the newest bio-based plastics. Designers, marketers, academics, and engineers will all find something of value in this balanced and thoughtful second edition. Increased public scrutiny of plastics materials and the plastics industry has led, paradoxically, to both a deeper understanding and growing confusion about polymers, their origins, their uses, their risks, and ultimately their disposal. The author makes objective comparisons among major polymer grades and bioplastics including their life cycle assessments and practical performance in commercial applications.
Polymer composites are materials in which the matrix polymer is reinforced with organic/inorganic fillers of a definite size and shape, leading to enhanced performance of the resultant composite. These materials find a wide number of applications in such diverse fields as geotextiles, building, electronics, medical, packaging, and automobiles. This first systematic reference on the topic emphasizes the characteristics and dimension of this reinforcement. The authors are leading researchers in the field from academia, government, industry, as well as private research institutions across the globe, and adopt a practical approach here, covering such aspects as the preparation, characterization, properties and theory of polymer composites. The book begins by discussing the state of the art, new challenges, and opportunities of various polymer composite systems. Interfacial characterization of the composites is discussed in detail, as is the macro- and micromechanics of the composites. Structure-property relationships in various composite systems are explained with the help of theoretical models, while processing techniques for various macro- to nanocomposite systems and the influence of processing parameters on the properties of the composite are reviewed in detail. The characterization of microstructure, elastic, viscoelastic, static and dynamic mechanical, thermal, tribological, rheological, optical, electrical and barrier properties are highlighted, as well as their myriad applications. Divided into three volumes: Vol. 1. Macro- and Microcomposites; Vol. 2. Nanocomposites; and Vol. 3. Biocomposites.
The open access publication of this book has been published with the support of the Swiss National Science Foundation. The massive accumulation of plastics in marine environments is one of the most pressing environmental concerns of our time. This book examines the relevant international legal framework applying to land-based sources of plastic pollution. Against the backdrop of the dynamics of recent policy formulation in this field, it outlines the main developments and provides a snapshot inventory of state obligations related to plastic pollution mitigation. The Mitigation of Marine Plastic Pollution in International Law identifies the main barriers and opportunities, and points out the possible building blocks of an enhanced regime.

The carefully culled content includes groundbreaking work from the earlier published work as well as exclusive online material added since its publication in print. A diverse and global team of renowned scientists provide cutting edge information concerning polymers and polymeric biomaterials. Acknowledging the evolving nature of the field, the encyclopedia also features newly added content in areas such as tissue engineering, tissue repair and reconstruction, and biomimetic materials.
Continuing the tradition of its previous editions, the third edition of Introduction to Polymer Chemistry provides a well-rounded presentation of the principles and applications of natural, synthetic, inorganic, and organic polymers. With an emphasis on the environment and green chemistry and materials, this third edition offers detailed coverage of natural and synthetic giant molecules, inorganic and organic polymers, biomacromolecules, elastomers, adhesives, coatings, fibers, plastics, blends, caulks, composites, and ceramics. Using simple fundamentals, the book demonstrates how the basic principles of one polymer group can be applied to all of the other groups. It covers reactivities, synthesis and polymerization reactions, techniques for characterization and analysis, energy absorption and thermal conductivity, physical and optical properties, and practical applications. This edition addresses environmental concerns and green polymeric materials, including biodegradable polymers and microorganisms for synthesizing materials. Case studies woven within the text illustrate various developments and the societal and scientific contexts in which these changes occurred. Now including new material on environmental science, Introduction to Polymer Chemistry, Third Edition remains the premier book for understanding the behavior of polymers. Building on undergraduate work in foundational courses, the text fulfills the American Chemical Society Committee on Professional Training (ACS CPT) in-depth course requirement.
