Book excerpt: Highly functionalized polymers represent a broad family of polymers with multiple functionalities attached to each repeat unit in the backbone. These can be small molecule functional groups or polymer sidechains grown or grafted from these functional groups. The latter leads to a class of polymers defined as comb polymers. This type of structure enforces a highly stretched conformation of the polymer backbone and imparts unique properties due to low inter chain entanglement and low entropic penalty for self-assembly. The comb polymers have a diverse set of architectures and compositions with potential applications in surface modification, resin formulation and nanopatterning. To realize this potential, efficient, versatile and easy-to-handle synthetic methods need to be constantly evolved. This dissertation focuses on the synthesis of comb polymers based on a new monomer and the application of multi-component reactions to reduce synthetic complexity. The first part of this dissertation focuses on the design of a benign formamide monomer capable of undergoing isocyanide-based multi-component reaction. The synthesis, polymerizability, reactivity and stability of this monomer is studied, along with its utility in the synthesis of comb polymers. Specifically, a difunctional polymerizable initiator (Y-inimer) that can be used for two tandem controlled polymerizations is designed from the formamide monomer. The utility of this Y-inimer is demonstrated through the synthesis of a comb polymer with 1:1 ratio of A and B chains, and A/B mixed polymer brushes from a substrate where intimate contact between the A and B chains is beneficial for exploring polyelectrolyte behavior. Finally, a comb polymer-based block copolymer additive is explored for synergistically improving the toughness and strength of a 3D printable epoxy resin. The main contribution of this dissertation lies in the 1) design of benign monomer that can be used in isocyanide-based multicomponent reactions to design highly functional polymers, without having to directly handle the isocyanide, 2) development of a dualfunctional polymerizable initiator for the synthesis of comb polymers with exact 1:1 ratio of A and B sidechains, and 3) development of a comb polymer additive for toughening of epoxy resin without loss of modulus or rheological properties.

Available in PDF, EPUB and Kindle. Book excerpt: Functionalized polymers are macromolecules to which chemically bound functional groups are attached which can be used as catalysts, reagents, protective groups, etc. Functionalized polymers have low cost, ease of processing and attractive features for functional organic molecules. Chemical reactions for the introduction of functional groups in polymers and the conversion of functional groups in polymers depend on different properties. Such properties are of great importance for functionalization reactions for possible applications of reactive polymers. This book deals with the synthesis and design of various functional polymers, the modification of preformed polymer backbones and their various applications.

Book excerpt: Conjugated polymers have been the focus of intense research for more than a decade now, and advances in this field are beginning to materialize in the production of high-efficiency opto-electronic materials that may led to the generation of energy without the need for fossil fuels. However, these current materials have not been shown to be capable of reaching efficiency levels high enough to be competitive with the silicon-based solar cells that are the standard today. We embarked on a journey in this work to help the next step in conjugated polymer research be attained. We have done just that through a fundamental study of dilution solution properties of these materials in addition to the synthetic pathway we have cleared so that highly functionalized conjugated polymers may be synthesized that will lead to block copolymers with tailored properties. These materials will revolutionize the field of organic photovoltaics and organic field transistors. The synthetic method for the generation of functionalized conjugated polymers described here represents an approach that can used to impart any number of functionalities onto the conjugated polymer chains which will lead directly to block copolymer systems. We have shown this ability through the synthesis of a diblock copolymer with promise of a miktoarm star block copolymer in this work. The versatility of the method developed here allows for other combinations of polymers and molecular architectures to be attainable in like manner. This work serves to provide other means by which these useful polymers may reach their maximum potential.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes original research aimed at the development of highly efficient polymer functionalization strategies by introducing orthogonal chemistry within polymeric systems. The primary hypothesis of this thesis is that the use of click chemistries or noncovalent interactions can provide new and easy pathways towards the synthesis of highly functionalized polymers thereby addressing the shortcomings of traditional covalent functionalization approaches. To verify the hypothesis, the work presented in the following chapters of this thesis further explores previous methods of either covalent or noncovalent polymer functionalization described in Chapter 1. Chapters 2 and 3 present advanced methods of covalent polymer functionalization based on high-yielding and orthogonal click reactions: 1,3-dipolar cycloaddition, hydrazone formation, and maleimide-thiol coupling. All three click reactions employed can be orthogonal to one another and conversions can be quantitative, leading to the easy and rapid synthesis of highly functionalized polymers without interference among functional handles along the polymer backbones.

Download or read book Functional Polymers by Post Polymerization Modification written by Patrick Theato and published by John Wiley & Sons. This book was released on 2013-02-12 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
