Available in PDF, EPUB and Kindle. Book excerpt: A mission to manage ever increased energy demands and reduce carbon foot print has challenged scientists and engineers to develop new materials with superior characteristics. In this scenario, lithium-ion batteries have been the dominating technology for not only applications in consumer electronics but also are essential for clean energy storage. On the other hand, the capture and separation of CO2 [carbon dioxide] in power generation and in industrial processes is considered to be a key to reduce the carbon footprint. Living anionic polymerization along with controlled polymerization techniques has realized the preparation of a wide variety of functional polymers with tunable properties. In this dissertation, we will present preparation of hetero-atom containing polymers using various polymerization techniques and post-polymerization modifications. We also want to explore: how can we employ these functional polymers to solve the current challenging problems? In chapter 1, we present the review of the state of the art polymer electrolytes for next-generation lithium ion batteries followed by the introduction of current CO2 [carbon dioxide] fixation and CO2/N2 [carbon dioxide/ nitrogen] gas separation techniques. In chapter 2, we discuss the synthetic methodology and experimental techniques including living anionic polymerization using high vacuum techniques, cationic ring opening polymerization techniques and hydrosilylation. In chapter 3 and chapter 4, we discuss the preparation of ambipolar polymer electrolytes and polymerized ionic liquids based on polydimethylsiloxane. The characterization, lithium ionic conductivity and structure-properties relationship are discussed. Chapter 5 describes a novel method to obtain living anionic polymerization of 2-isopropenyl-2-oxazoline. Through our modified synthetic conditions, block copolymers of IPOx are also prepared and microphase separations are studied. In chapter 6, we investigate the synthesis gold nanoparticle using PIPOx as template. The size of god nanoparticles will be analyzed using TEM [transmission electron microscopy] and AFM [atomic force microscopy]. Furthermore, the interactions between PIPOx [poly(2-isopropenyl-2-oxazoline)] template and AuNPs [gold nano particles] is studied using XPS [X-ray photoelectron spectroscopy]. In chapter 7, we introduce the preparation of amidoxime-modified PTMSP [poly(1-trimethylsilyl-1-propyne)] and its applications on CO2/N2 [carbon dioxide/ nitrogen] separation. Finally, the research in this dissertation is summarized and future work is presented in chapter 8.

Available in PDF, EPUB and Kindle. Book excerpt: Organometallic Polymers focuses on the synthesis, characterization, and potential applications of organometallic polymers. The discussion is organized around seven themes: vinyl polymerization of organometallic monomers; condensation polymerization of organometallic monomers; polymer-bound catalysts; applications of organotin polymers; developments in organosilicon polymers; phosphonitrile and sulfur nitride polymers; and coordination polymers. This book is comprised of 33 chapters and begins with a general review of polymerized vinyl monomers containing transition metals, as well as the reactivity of such monomers in addition to homo- and copolymerizations. The following chapters explore the participation of the ferrocene nucleus in the polymerization of vinylferrocene and its effect on polymer properties; thermomechanical transitions of ferrocene-containing polymers; photocrosslinkable organometallic polyesters; and supported catalysts for ethylene polymerization. The remaining sections discuss antifouling applications of various tin-containing organometallic polymers; structure and applications of polyphosphazenes and polymeric sulfur nitride; and coordination of inorganic ions to polymers. This monograph will be a useful resource for organic chemists and research workers in the field.

This book was released on 2011 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amphiphilic ionic block copolymers are promising materials for the fabrication of ion-exchange membranes in fuel cells, water purification and advanced molecular engineering applications, such as nanotemplating. For example, block copolymer architectures provide a route to fabricate membranes with tunable transport properties through polymer self assembly. A significant challenge in this field is the synthesis of amphiphilic copolymers, where the intrinsic immiscibility of the hydrophobic and hydrophilic monomers complicates polymerization. To address the immiscibility between sodium p-styrenesulfonate and styrene monomers, styrenesulfonate monomers were neutralized by hydrophobic trialkyl ammonium salts via ion-exchange reactions, and synthesized successfully by RAFT polymerization with low polydispersity (PDI). Diblock or triblock copolymers with well-defined architectures were obtained by sequential RAFT polymerization with styrene. These sulfonate groups were then converted to the sodium salt form via ion-exchange to obtain amphiphilic ionic block copolymers. It was observed that dimethyl n-alkyl ammonium salts of polystyrenesulfonate displayed thermo-reversible gelation behavior in low polarity organic solvents. The investigation of the gelation behavior as a function of temperature, concentration, and solvent was consistent with gelation driven by the ionic aggregation of the polymer as would be expected for polyelectrolyte surfactant complexes in non-polar solvents. Cationic amphiphilic block/graft copolymers containing quaternary ammonium salts were prepared by the RAFT polymerization of polystyrene-b-poly(vinylbenzyl chloride) (PS-b-PVBC) copolymers, and sequential post-polymerization quaternization of the PVBC blocks. PS-b-PVBEA-b-PS triblock copolymers with well-defined architectures were obtained and the ion conductivity of the corresponding membranes, as well as the morphology of the membranes, was investigated. To improve the mechanical properties of the membranes, different architectures, such as pentablock, heptablock and graft copolymers, were designed and synthesized by RAFT polymerization, and chemical crosslinking was employed to improve the mechanical properties and control the swelling in water. Lastly, a new method to prepare multiblock copolymers via a facile route was developed. Polytrithiocarbonates were prepared by condensation polymerization of a dicarboxylic acid functional trithiocarbonate and a diol, and the trithiocarbonate group was controlled by tuning the amount of acid catalyst and reaction time. The polytrithiocarbonate RAFT agents were used to polymerize PS, polystyrene-b-poly (tert-butylstyrene) (PS-b-PtBS), and PS-b-PVBC. The PDI of the polymers toward 2, but the PDI of the polymer blocks between two trithiocarbonate groups was narrow (1.1-1.3 for PS and PS-b-PtBS, and 1.46 for PS-b-PVBC). The PVBC segments were quaternized to achieve anionic amphiphilic multiblock copolymers.

This book was released on 2012-12-06 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on metal-containing polymers began in the early 1960's when several workers found that vinyl ferrocene and other vinylic transition metal TI -complexes would undergo polymerization under the same conditions as conventional organic monomers to form high polymers which incorporated a potentially reactive metal as an integral part of the polymer structures. Some of these materials could act as semi conductors and possessed one or two dimensional conductivity. Thus applications in electronics could be visualized immediately. Other workers found that reactions used to make simple metal chelates could be used to prepare polymers if the ligands were designed properly. As interest in homogeneous catalysts developed in the late 60's and early 70's, several investigators began binding homogeneous catalysts onto polymers, where the advantage of homogeneous catalysis - known reaction mechanisms and the advantage of heterogeneous catalysis - simplicity and ease of recovery of catalysts could both be obtained. Indeed the polymer matrix itself often enhanced the selectivity of the catalyst. The first symposium on Organometallic Polymers, held at the National Meeting of the American Chemical Society in September 1977, attracted a large number of scientists interested in this field, both established investigators and newcomers. Subsequent symposia in 1977, 1979, 1983, and 1987 have seen the field mature. Hundreds of papers and patents have been published.
