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)

Designing polymers and developing polymerization processes that are safe, prevent pollution, and are more efficient in the use of materials and engergy is an important topic in modern chemistry. Today, green polymer research can be seen increasingly in academia nd industry. It tackles all aspects of polymers and polymerization - everything from chemical feedstocks, synthetic pathways, and reaction media to the nature of the final polymer as related to its inherent nontoxicity or degradability. This book summarizes and evaluates the latest developments in green polymerization methods. Specifically, new catalytic methods and processes which incorporate renewable resources will be discussed by leading experts in the field of polymer chemistry. This book is a must-have for Polymer Chemists, Chemists Working with/on Organometallics, Biochemists, Physical Chemists, Chemical Engineers, Biotechnologists, Materials Scientists, and Catalytic Chemists.

Smart Polymer Nanocomposites: Biomedical and Environmental Applications presents the latest information on smart polymers and their promising application in various fields, including their role in delivery systems for drugs, tissue engineering scaffolds, cell culture sports, bioseparation, and sensors or actuator systems. - Features detailed information on the preparation, characterization and applications of smart functional polymer composites - Covers a broad range of applications in both the biomedical and environmental engineering fields - Chapters are written by authors with diverse background expertise from the faculties of chemistry, engineering and the manufacturing industry

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.
