Download or read book Template Polymerization written by Stefan Polowinski and published by ChemTec Publishing. This book was released on 1997 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Template polymerization is a new field in polymer synthesis but common practice in the biosynthesis since DNA is the most popular template or matrix on which proteins are built by living species. This field is relevant to the synthesis of polymers of controlled structure but its application goes beyond the synthesis. Materials are formulated in complex mixtures always containing components which can be regarded as templates on which other materials are formed, modified, or are interacted with. In the new product development the relevance of these phenomena is controlled by the order of addition which affects probabilities and preferences of interaction. The current publication outlines mechanisms of template polymerization, polycondensation, and copolymerization. These mechanisms, illustrated with numerous examples, indicate a range of possibilities which can be encountered in materials and utilized to modify their properties. Orientation of substrates on template and their effect on modification of their reactivity and properties such as, for example, absorption of light or water are also discussed. Several chapters contain information on these studies discussed with sufficient detail to give reader comprehensive understanding of the methods used in various research laboratories and their findings."--Publisher's description.

Book excerpt: The progress in polymer science is revealed in the chapters of Polymer Science: A Comprehensive Reference, Ten Volume Set. In Volume 1, this is reflected in the improved understanding of the properties of polymers in solution, in bulk and in confined situations such as in thin films. Volume 2 addresses new characterization techniques, such as high resolution optical microscopy, scanning probe microscopy and other procedures for surface and interface characterization. Volume 3 presents the great progress achieved in precise synthetic polymerization techniques for vinyl monomers to control macromolecular architecture: the development of metallocene and post-metallocene catalysis for olefin polymerization, new ionic polymerization procedures, and atom transfer radical polymerization, nitroxide mediated polymerization, and reversible addition-fragmentation chain transfer systems as the most often used controlled/living radical polymerization methods. Volume 4 is devoted to kinetics, mechanisms and applications of ring opening polymerization of heterocyclic monomers and cycloolefins (ROMP), as well as to various less common polymerization techniques. Polycondensation and non-chain polymerizations, including dendrimer synthesis and various "click" procedures, are covered in Volume 5. Volume 6 focuses on several aspects of controlled macromolecular architectures and soft nano-objects including hybrids and bioconjugates. Many of the achievements would have not been possible without new characterization techniques like AFM that allowed direct imaging of single molecules and nano-objects with a precision available only recently. An entirely new aspect in polymer science is based on the combination of bottom-up methods such as polymer synthesis and molecularly programmed self-assembly with top-down structuring such as lithography and surface templating, as presented in Volume 7. It encompasses polymer and nanoparticle assembly in bulk and under confined conditions or influenced by an external field, including thin films, inorganic-organic hybrids, or nanofibers. Volume 8 expands these concepts focusing on applications in advanced technologies, e.g. in electronic industry and centers on combination with top down approach and functional properties like conductivity. Another type of functionality that is of rapidly increasing importance in polymer science is introduced in volume 9. It deals with various aspects of polymers in biology and medicine, including the response of living cells and tissue to the contact with biofunctional particles and surfaces.

Download or read book Handbook of Polymer Research written by Gennadii Efremovich Zaikov and published by Nova Publishers. This book was released on 2006 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers are substances containing a large number of structural units joined by the same type of linkage. These substances often form into a chain-like structure. Starch, cellulose, and rubber all possess polymeric properties. Today, the polymer industry has grown to be larger than the aluminium, copper and steel industries combined. Polymers already have a range of applications that far exceeds that of any other class of material available to man. Current applications extend from adhesives, coatings, foams, and packaging materials to textile and industrial fibres, elastomers, and structural plastics. Polymers are also used for most composites, electronic devices, biomedical devices, optical devices, and precursors for many newly developed high-tech ceramics. This new volume presents leading-edge research in this rapidly-changing and evolving field.
