Available in PDF, EPUB and Kindle. Book excerpt: Advances in Polymer Science enjoys a longstanding tradition and good reputation in its community. Each volume is dedicated to a current topic, and each review critically surveys one aspect of that topic, to place it within the context of the volume. The volumes typically summarize the significant developments of the last 5 to 10 years and discuss them critically, presenting selected examples, explaining and illustrating the important principles, and bringing together many important references of primary literature. On that basis, future research directions in the area can be discussed. Advances in Polymer Science volumes thus are important references for every polymer scientist, as well as for other scientists interested in polymer science - as an introduction to a neighboring field, or as a compilation of detailed information for the specialist.

Download or read book Atom Transfer Radical Polymerization written by Tharanikkarasu Kannan and published by LAP Lambert Academic Publishing. This book was released on 2010-05 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional radical polymerization is widely used in industries due to its simple polymerization conditions. But, molecular weight of polymers are difficult to control in this method. To achieve control over molecular weight and molecular weight distribution, many controlled radical polymerization methods have been proposed such as INIFERTER, NMP, RAFT and ATRP. In the field of ATRP, due to its simplicity and versatility, more than 7000 research articles have been published in the reputed journals during the last 15 years. But polyurethane-based tri-block copolymers have not been reported so far through ATRP and hence this book concentrates on novel routes to synthesize these tri-block copolymers via ATRP. Four different types of polyurethane macroinitiators for ATRP have been synthesized and used for the polymerization of vinyl and acrylate monomers. Results show that the present macroinitiators polymerize monomers through ATRP mechanism. These macroinitiators are highly potential to polymerize wide variety of monomers and resulting block copolymers would be very useful for academic as well as industrial research.

Download or read book Synthesis and Characterization of Gradient Hyperbranched Copolymers by Atom Transfer Radical Polymerization written by and published by . This book was released on 2000 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis of linear and (hyper)branched polymers possessing varying compositions using atom transfer radical polymerization (ATRP) was conducted. The synthesis of linear random and gradient copolymers from styrene/n-butyl acrylate and methyl methacrylate/n-butyl acrylate systems were evaluated by studying the copolymerization kinetics of the respective monomers pairs in ATRP. Development in the preparation of materials with advanced architectures was achieved by the synthesis of novel hyperbranched polymers using the self-condensing vinyl polymerization (SCVP) by ATRP. Subsequent end-group transformation reactions of these hyperbranched polymers yielded low viscosity materials with reactive functionalities. Additionally, novel highly branched nanocomposites were also prepared by the use of a functional colloid (diameter = 15 nm) as a macroinitiator for the synthesis of homo- and block copolymers tethered to a particle surface.

Download or read book Synthesis and Self assembly of Advanced Bottlebrush Block Copolymers written by Justin Bolton and published by . This book was released on 2012 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using the grafting-from approach, three novel well-defined bottlebrush block copolymers were synthesized using various controlled polymerization techniques. Resulting macromolecules were characterized by GPC and 1H NMR and then self-assembled into nanostructured materials for further characterization. Asymmetric polystyrene-polylactide (PS-PLA) bottlebrush block copolymers have been shown to self-assemble into a cylindrical morphology with large domain spacings. PLA cylinders can be selectively etched out of the shear-aligned polymer monoliths to generate nanoporous materials with an average cylindrical pore diameter of 55 nm. The remaining bottlebrush backbone provides a functional, hydrophilic coating inside the nanopores. This methodology significantly expands the range of pore sizes attainable in block copolymer based nanoporous materials.^A polystyrene-poly(methyl methacrylate) (PS-PMMA) bottlebrush block copolymer with asymmetric branches was synthesized by grafting from a symmetrical backbone containing a novel dual vinyl initiation system and characterized by atomic force microscopy (AFM) and small-angle x-ray scattering (SAXS). The block copolymer backbone was prepared by sequential reversible addition-fragmentation chain transfer (RAFT) copolymerization of solketal methacrylate and 2-(bromoisobutyryl)ethyl methacrylate (BIEM). From the poly(BIEM) segment, PMMA branches were grafted by atom transfer radical polymerization (ATRP). Solketal groups were then subjected to hydrolysis and functionalized with a RAFT agent. Subsequently, from RAFT sites of the poly(SM) segment, polystyrene branches were grafted to yield the final bottlebrush block copolymer.^The resulting polymer was found to have a vertically oriented cylindrical morphology by AFM with an average cylinder diameter of 45 nm; morphology was also confirmed by SAXS analysis. A novel polylactide-poly(methyl methacrylate)-polystyrene (PLA-PMMA-PS) triblock bottlebrush block copolymer was synthesized from a triblock backbone employing ATRP, RAFT and ROP techniques. Novel 5-TMS-4-pentyn-1-ol methacrylate (TPYM) with protected alkyne functionality was developed and characterized as a homopolymer. Click chemistry was used to introduce RAFT groups along the homopolymer backbone. Subsequently, PS branches were grafted from RAFT initiators along the backbone. A well-defined poly(SM-b-BIEM-b-TPYM) backbone was synthesized followed by grafting of PMMA brushes from the BIEM segment by ATRP.^Post PMMA grafting, the ATRP end groups were removed and the TMS group was deprotected to allow functionalization of the alkyne with an azido terminated RAFT agent by way of Huisgen 1,3-dipolar cycloaddition. From the RAFT sites, PS was grafted followed by deprotection of the hydroxyl functionality of the SM block. Resulting liberated hydroxyls were used to initiate PLA grafts, yielding the final well-defined triblock bottlebrush block copolymer (PLA-PMMA-PS).
