In modern polymer science a variety of polymerization methods for the direct synthesis of polymers bearing functional groups are known. However, there is still a large number of functional groups that may either completely prevent polymerization or lead to side reactions. Post-polymerization modification, also known as polymer-analogous modification, is an alternative approach to overcome these limitations. It is based on the polymerization of monomers with functional groups that are inert towards the polymerization conditions but allow a quantitative conversion in a subsequent reaction step yielding a broad range of other functional groups. Thus, diverse libraries of functional polymers with identical average degrees of polymerization but variable side chain functionality may easily be generated. Filling the gap for a book dealing with synthetic strategies and recent developments, this volume provides a comprehensive and up-to-date overview of the field of post-polymerization modification. As such, the international team of expert authors covers a wide range of topics, including new synthetic techniques utilizing different reactive groups for post-polymerization modifications with examples ranging from modification of biomimetic and biological polymers to modification of surfaces. With its guidelines this is an indispensable and interdisciplinary reference for scientists working in both academic and industrial polymer research.

Post-polymerization modification of polymers is an important tool for accessing macromolecular materials with desired functional groups and tailored properties. Such strategy may become the only route to a target polymer when the availability or reactivity of the corresponding monomer is not suited for direct polymerization. Most post-polymerization modification processes are based on transforming functional groups that are pre-installed in the side chains or chain-ends of a polymer. Despite the excellent efficiency and versatility, they are limited to certain backbone structures and often require additional synthetic effort for the synthesis of the corresponding pre-functionalized monomers. More specifically, they are useful only when the pre-functionalized monomers can be readily prepared and incorporated to a polymer by direct polymerization. In contrast, direct functionalization of C-H bonds along the polymer backbone offers a markedly different strategy for the synthesis of functional polymers. Despite the inert nature, the ubiquity of the C-H bonds and their tunable reactivity make them ideal targets for selective chemical modification. In this dissertation, it is first demonstrated that poly(vinyl ester)s and poly(vinyl ether-co-vinyl ester) can be readily prepared via a ruthenium catalyzed C–H oxyfunctionalization of the corresponding poly(vinyl ether)s under mild conditions. The method can be further applied for the synthesis of high molecular weight poly(propenyl ester)s which cannot be obtained using other methods. In addition the method allows poly(isopropenyl ester) to be synthesized without the use of extremely high pressures. Using a similar strategy poly(ethylene glycol-co-glycolic acid) can be prepared by the ruthenium-catalyzed oxidation of poly(ethylene glycol) (PEG). A new process has been developed so that the transformation will cause little chain degradation. The presence of the hydrolytically labile ester groups in the PEG backbone renders the copolymer biodegradable, which may allow the PEG of higher molecular weight to be used in biomedical applications without the concerns of bioaccumulation of PEG into various organs. Lastly, it is demonstrated that azido-functionalized, isotactic polypropylene can be prepared via the direct C–H azidation of a commercially available polymer using a stable azidoiodinane. The azidated PP can further undergo copper-catalyzed azide-alkyne cycloaddition with alkyne terminated polymer to obtain PP-based graft copolymers. It is expected that the ability to incorporate versatile functional groups, such as azides, into common polyolefin feedstocks should expand their applications and potentially enable the realization of new classes of materials.

Polyolefins are the most widely used commercial polymers and their functionalization has been a long standing scientific challenge and an industrially important area. In recent decades significant progress has been made in the area, with exciting results reported in many journals. Functionalization of Polyolefins is the first book to summarize the significant experimental results on the functionalization of polyolefins and classify them into several chemical methods (shown in each chapter of this book). The book also provides an update on the functional polyolefin materials available today. The two key subject categories covered are: - Chemical approaches in the functionalization of polyolefins - New available polyolefin materials and their potential applications The book includes: - The historic development and future prospects for polyolefins - Functionalization chemistry, classified into four general approaches - Chemical approaches with experimental results - Functionalization approaches The book provides an invaluable reference for researchers in industry and academia interested in functionalization chemistry and polymers. It has been developed through Professor Chung's own teaching experience, both at Pennsylvania State University and on short courses. It is therefore ideally suited as a core text for advanced polymer chemistry and courses on polyolefins and polymers, as well as being a useful supplementary reference for introductory courses on polyolefin chemistry and materials. T.C. Mike Chung is Professor of Polymer Science in the Materials Science and Engineering Department, Pennsylvania State University, USA. He is one of the most experienced people in the field of polyolefin functionalization, with a wide-ranging knowledge gained through many years of experience both in academia and industry. - Shows the available functionalisation approaches with a discussion of their scope and limitations - Written by one of the most experienced people in this field

The sheer volume of topics which could have been included under our general title prompted us to make some rather arbitrary decisions about content. Modification by irradiation is not included because the activity in this area is being treated elsewhere. We have chosen to emphasize chemical routes to modification and have striven to pre sent as balanced a representation of current activity as time and page count permit. Industrial applications, both real and potential, are included. Where appropriate, we have encouraged the contributors to include review material to help provide the reader with adequate context. The initial chapter is a review from a historical perspective of polymer modification and contains an extensive bibliography. The remainder of the book is divided into four general areas: Reactions and Preparation of Copolymers Reactions and Preparation of Block and Graft Copolymers Modification Through Condensation Reactions Applications The chemical modification of homopolymers such as polyvinylchlo ride, polyethylene, poly(chloroalkylene sulfides), polysulfones, poly chloromethylstyrene, polyisobutylene, polysodium acrylate, polyvinyl alcohol, polyvinyl chloroformate, sulfonated polystyrene; block and graft copolymers such as poly(styrene-block-ethylene-co-butylene block-styrene), poly(I,4-polybutadiene-block ethylene oxide), star chlorine-telechelic polyisobutylene, poly(isobutylene-co-2,3-dimethyl- 1,3-butadiene), poly(styrene-co-N-butylmethacrylate); cellulose, dex tran and inulin, is described.
