Polymer chemistry and technology form one of the major areas of molecular and materials science. This field impinges on nearly every aspect of modern life, from electronics technology, to medicine, to the wide range of fibers, films, elastomers, and structural materials on which everyone depends. Although most of these polymers are organic materials, attention is being focused increasingly toward polymers that contain inorganic elements as well as organiccomponents. The goal of Inorganic Polymers is to provide a broad overview of inorganic polymers in a way that will be useful to both the uninitiated and those already working in this field. There are numerousreasons for being interested in inorganic polymers. One is the simple need to know how structure affects the properties of a polymer, particularly outside the well-plowed area of organic materials. Another is the bridge that inorganic polymers provide between polymer science and ceramics. More and more chemistry is being used in the preparation of ceramics of carefully controlled structure, and inorganic polymers are increasingly important precursor materials in such approaches.This new edition begins with a brief introductory chapter. That is followed with a discussion of the characteristics and characterization of polymers, with examples taken from the field. Otherchapters in the book detail the synthesis, reaction chemistry, molecular structure, and uses of polyphosphazenes, polysiloxanes, and polysilanes. The coverage in the second edition has been updated and expanded significantly to cover advances and interesting trends since the first edition appeared. Three new chapters have been added, focusing on ferrocene-based polymers, other phosphorous-containing polymers, and boron-containing polymers; inorganic-organic hybrid composites; and preceramicinorganic polymers.

Polyphosphazenes are polymers containing nitrogen as part of their backbone; they are commonly used in O-rings, pipelines, and seals in oil, fuel delivery, and storage systems. New polyphosphazene derivatives have been proven biocompatible, biodegradable, and bioactive, and some of them are being investigated for possible medical applications.Harry Allcock’s Chemistry and Applications of Polyphosphazenes provides the only published compilation of material on polyphosphazenes, detailing synthetic methodologies and physical properties for each substance. Allcock explains the critical relationships between structure and properties, aiding the practicing researcher in the design of polyphosphazenes with specific applications. Professionals and students in polymer science, engineering, and industries such as rubbers and plastics will find Chemistry and Applications of Polyphosphazenes to be an invaluable text.

A symposium titled "Polyphosphazenes in Biomedicine, Engineering & Pioneering Synthesis" was held at a recent meeting of the American Chemical Society (ACS) in August 2017 in Washington, DC. The chapters in this book provide a summary of the international contributions reported at that meeting, the purpose of which was to bring together a broad range of topics, research investigators, and representatives from industry to discuss the current status of differentaspects of this field.
