Polymer modifications represent a valuable synthetic approach to unique polymer compositions, structure, and properties not readily available by the direct polymerization of monomers. Modified polymeric products already exist in the commercial world (modified celluloses, for example) so the approach is not new. However, it is an interesting and chaU~nging opportunity to develop new materials for a variety of specialty applications using the "chemistry on polymers" approach. This book contains papers presented at the symposium on Polymer Modification held at the National American Chemical Society Meeting in Orlando, Florida, August, 1996. The chemistry presented is broad ranging, and includes grafting and chemical oxidation reactions, and many other chemical modifications. Hopefully, the book will be both a resource and an inspiration for the reader to develop new opportunities for his or her particular applications.

Although in nature, the vast majority of polymers are condensation polymers, much publicity has been focused on functionalized vinyl polymers. This text aims to fulfill the need to explore these polymers which form an increasingly important and diverse foundation in the search for new materials in the 21st century. Some of the advantages condensation polymers hold over vinyl polymers include offering different kinds of binding sites, their ability to be made biodegradable, and their different reactivities with various reagents under diverse reaction conditions. They also offer better tailoring of end-products, different tendencies (such as fibre formation), and different physical and chemical properties. Some of the main areas emphasized include dendrimers, control release of drugs, nanostructure materials controlled biomedical recognition, and controllable electrolyte and electrical properties.
