    • is an Evan Pugh Prqf2ssor of Chemistry at the Pennsylvania State University. He is one of the leading experts in the, field of inorganic-organic polymers, and materials derived, from them. His early training was in organometallic and physical-organic chemistry, his B.Sc. and Ph.D. degrees being awarded by the University of London. His interest in polymers and materials developed during two postdoctoral appointments and five years as a research scientist at the American Cyanamid Central Research Laboratories. Since 1966 lie has Ieda team at Penn State that has made many of the fundamental discoveries in the chemistry of polyphosphazenes and related systems and has been responsible for developments in areas as diverse as biomedicine, energy storage, communications science, and novel structural materials. He was the recipient of the 1984 American Chemical Society National Award in Polymer Chemistry and the 1992 ACS Award in the Chemistry of Materials. He is the author or co-author of over 300 publications, including four books, in the, field of inorganic-organic polymers and materials.

It is also a pleasure to acknowledge the contributions of many co-workers who have participated in the research on polyphosphazenes and related systems.


Polymers with an inorganic backbone and organic or organometallic side groups are one of the most promising approaches to new materials that combine the advantages of organic polymers with those of inorganic solids. Properties conferred by particular backbone elements and side groups are discussed, and methods of synthesis briefly outlined. The figure shows the result of a novel variation of ring-opening polymerization.
