Summary:

Design and synthesis of structurally well-defined polymers is one of the areas of current technology interest for niche product applications. Major research efforts are focused on moving from coordination-addition to advanced radical polymerization methodology to produce new polymeric structures using polar and/or non-polar monomer for different end use applications. In this book, the authors present topical research on new developments in radical polymerization. Topics discussed include interface radical reactions of functional polyperoxides for fabrication of three-dimensional polymeric structures; biomacromolecules in radical processes; nitroxide-mediated photo controlled/living radical polymerization; alkaline anion-exchange membranes prepared by plasma polymerization; advancements in controlled radical polymerization for functional polymers and thermal redox and photoinduced ring opening polymerization reactions.
