Available in PDF, EPUB and Kindle. Book excerpt: The methodology of conventional free radical polymerization was employed throughout our research to study polymerization behavior in three RTILs (room temperature ionic liquids): 1-butyl-3-methylimidazolium hexafluoroposphate ([BMIM]PF6), (tetrabutylammonium dioctyl) sulfosuccinate (Terrasail) and (1-isopropyl- 3-methylimidazolium) methanesulfonate (Marisail). Sequential addition free radical polymerization in RTILs emerged as a new route to obtain polystyrene - poly(methyl methacrylate) block copolymers. We applied the same strategy to the block copolymerization of other two systems: the monomer pair of styrene-vinyl acetate in Terrasail, and the monomer pair of styrene-acrylic acid in [BMIM]PF6. While styrene-vinyl acetate block copolymers with a composition of 50% (VAc mol%) were obtained, the polymerization of styrene-acrylic acid only yielded polymers with mainly styrene units. Therefore, sequential addition free radical polymerization in RTILs is not effective on all polymerization systems (eg. Styreneacrylic acid/[BMIM]PF6). Our study on free radical homopolymerization of 2-hydroxyethyl methacrylate (HEMA) in RTILs showed that the positive effects of employing RTILs as reaction medium could be extended from polymerization of alkyl methacrylates to that of functional methacrylates. All of the reactions exhibited very high polymerization rates, and the resulting products possessed higher molecular weight than those polymers obtained using methanol as solvent. Copolymerizations of the monomer pairs styrene/vinyl acetate, styrene/acrylic acid, styrene/HEMA (2-hydroxyethyl methacrylate) were carried out in RTILs via conventional free radical polymerization. However, our results failed to show any dramatic effects of RTILs on the free radical copolymerization, although RTILs are believed to be able to enhance the rates of propagation while depressing the rates of termination in homopolymerizations.

Available in PDF, EPUB and Kindle. Book excerpt: Examination of the early literature attests to the fact that the study of copolymerization was initiated when polymer science was in its infancy. It has continued to grow to a subject of major importance and has been a source of interest to both academic and industrialist alike. The wide spectrum of structures and properties available in the statistical copolymer has made this a fruitful field of exploration, but one particular and more restricted form which has held its own fascination for many is the limiting case of the strictly alternating copolymer. This is formed, in the ideal situation, when two monomers in a reaction mixture add consecutively to create a polymer chain with a regular {ABABAB} structure, irrespective of the monomer feed ratio. When this happens the resulting copolymer will always have the same composition, a feature which can be advantageous but also somewhat restrictive, as the ability to vary the properties is then limited. Within a series entitled Speciality Polymers it seems appropriate then to deal with this subject, particularly as no previous attempt has been made to draw together the various facets of alternating copolymerization into one volume. It also seems timely to present a more unified picture of the subject which will also illustrate the progress made.

Available in PDF, EPUB and Kindle. Book excerpt: Nanocomposite Structures and Dispersions deals with the preparation of gelled, branched and crosslinked nanostructured polymers in the solution free radical polymerization and controlled/living radical polymerization and polymer and composite nanoparticles and nanostructures in disperse systems, the kinetics of direct and inverse disperse polymerizations (microemulsion, miniemulsion, emulsion, dispersion and suspension polymerization), the bottom-up approach building of functionalized nanoparticles, modelling of radical microemulsion polymerization, the characterization of traditional and non-traditional polymer dispersions, the collective properties of nanomaterials and their (bio)applications. This book is designed to bridge that gap and offers several unique features. First, it is written as an introduction to and survey of nanomaterials with a careful balance between basics and advanced topics. Thus, it is suitable for both beginners and experts, including graduate and upper-level undergraduate students. Second, it strives to balance the colloidal aspects of nanomaterials with physical principles. Third, the book highlights nanomaterial based architectures including composite or hybrid conjugates rather than only isolated nanoparticles. A number of ligands have been utilized to biodecorate the polymer and composite nanocarriers. Finally, the book provides an in depth discussion of important examples of reaction mechanisms of bottom-up building of functionalized nanoparticles, or potential applications of nanoarchitectures, ranging from physical to chemical and biological systems.

Available in PDF, EPUB and Kindle. Book excerpt: The Earth's natural resources are finite and easily compromised by contamination from industrial chemicals and byproducts from the degradation of consumer products. The growing field of green and sustainable chemistry seeks to address this through the development of products and processes that are environmentally benign while remaining economically viable. Inorganic chemistry plays a critical role in this endeavor in areas such as resource extraction and isolation, renewable energy, catalytic processes, waste minimization and avoidance, and renewable industrial feedstocks. Sustainable Inorganic Chemistry presents a comprehensive overview of the many new developments taking place in this rapidly expanding field, in articles that discuss fundamental concepts alongside cutting-edge developments and applications. The volume includes educational reviews from leading scientists on a broad range of topics including: inorganic resources, sustainable synthetic methods, alternative reaction conditions, heterogeneous catalysis, photocatalysis, sustainable nanomaterials, renewable and clean fuels, water treatment and remediation, waste valorization and life cycle sustainability assessment. The content from this book will be added online to the Encyclopedia of Inorganic and Bioinorganic Chemistry.
