Download or read book Polymerization of Heterocycles (Ring Opening) written by S. Penczek and published by Elsevier. This book was released on 2016-02-03 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymerization of Heterocycles (Ring Opening) is a collection of papers presented at the International Symposium on Polymerization of Heterocycles (Ring-Opening) held in Warsaw, Poland on June 23-25, 1975. The first paper describes the developments and physical meaning of ion pairs and higher ionic aggregates. Another paper explains the process of obtaining linear polymers, containing rings in the main chain. The book interprets the various behaviors of polymers that can result in high optical yields of stereoelectivity ratios equal to 8. The text then discusses future trends in aldehyde and carbonyl polymerization, including some problem areas pertaining to failures to homopolymerize or copolymerize tetrachloroethylene oxide. Another paper reviews the elemental reactions of selected combinations of copolymerization; the next paper discuses aspects of the mechanism of nucleophilic opening of epoxide rings through studies of certain kinetics. The book then analyzes the ability of lactams to undergo ring-opening polymerization, which mainly depends on the ring size and on the substitution and presence of heteroatoms in the lactam ring itself. The text also discusses the preparation, properties, and applications of the heterochain polymers in medicine or biologically active materials. The book can provide useful information for biochemists, researchers dealing with inorganic and organic compounds, and scientists working in the fields of chemistry such as synthetic chemistry, as well as polymer engineering.

Book Synopsis Catalytic Polymerization of Cycloolefins by : V. Dragutan
Download or read book Catalytic Polymerization of Cycloolefins written by V. Dragutan and published by Elsevier. This book was released on 2000-06-26 with total page 1293 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the most important topics concerning cationic Ziegler-Natta and ring-opening metathesis polymerization of cycloolefins. The work describes the major pathways that cycloolefins can follow under the action of specific catalytic systems, essentially vinyl and ring-opening polymerization, both reaction types allowing the manufacture of distinct products with wide applicability in modern technologies. The comprehensive data available on this subject are logically and systematically selected and reviewed throughout 18 chapters, according to the basic catalytic processes involved, types of monomers and catalysts employed, reaction conditions and application fields. The modern trends in design of chiral metallocene catalysts, well-defined living metathesis catalysts, catalysts tolerant toward functionalities and water systems are highlighted. The book discusses in detail the relevant aspects of these processes including reaction thermodynamics, kinetics, mechanisms and stereochemistry and correlates the structure of produced polymers with their chemical and physical-mechanical properties. Related important topics include Ziegler-Natta polymerization of olefins and dienes, atom transfer radical polymerization of vinyl compounds, metathesis of olefins and acetylenes, acyclic diene metathesis reaction, carbonyl olefination reaction, metathesis polymerization of acetylenes, metathesis degradation of polymers and ring-opening polymerization of heterocycles. Special emphasis is laid upon the manufacture of commerical products, new polymers and copolymers of potential interest for industry and design and synthesis of speciality polymers with particular structures and architectures and desired properties. The book critically evaluates the most recent achievements reported in this field and outlines the modern trends on the research and application of the catalytic processes for cycloolefin polymerization. For the first time, comprehensive information about the published data on the subject up to now is provided for both academic and industrial researchers working in the areas of polymer chemistry, organic and organometallic chemistry, surface science and catalysis, petrochemistry and chemical engineering. This stimulating book offers an enlightening introduction and a quick documentation on the subject as well as a solid background in this field. Moreover, the work offers a wealth of useful information for specialists applying polymers in various scientific and industrial areas.

Book Synopsis Polymers and Pyridazines by : Péter Tétényi
Download or read book Polymers and Pyridazines written by Péter Tétényi and published by CRC Press. This book was released on 2019-05-29 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few years, a few articles have been published on the solid-phase synthesis of pyridazine derivatives. These methods apply to intermediates weakly bound to polymers, as a result of which the ester bond is cleaved easily, either during ring closure or right after it. There are few polymer-supported syntheses of heterocycles. This book, Polymers and Pyridazines, discusses a new strategy for polymer-supported synthesis of pyridazine derivatives with much higher reaction rates, applying higher loading and much wider reaction conditions due to the more stable attachment. On the basis of the research conducted, a fundamental break-through was achieved in solid-phase heterocyclic chemistry. The experiments are accompanied by colored drawings and 3D diagrams to help understand the importance of swelling and/or excess concentrations of reagents. Detailed experiments provide complete procedures with infrared difference spectra. The book will be a helpful reference for academy polymer specialists and postgraduate students studying polymer syntheses of general substrates.

Book Synopsis Models of Biopolymers By Ring-Opening Polymerization by : Stanislaw Penczek
Download or read book Models of Biopolymers By Ring-Opening Polymerization written by Stanislaw Penczek and published by CRC Press. This book was released on 2018-01-18 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are a number of methods used to synthetically prepare biopolymers, their models, and bioanalogous polymers. This work approaches the syntheses of the three major groups of biopolymers existing in nature - polypeptides, polysaccharides, and nucleic and teichoic acids - by ring-opening polymerization. Until now, this method has never been reviewed uniformly for these three groups. The majority of models prepared by ring-opening polymerization can not reach the complexity of the actual biological molecules. However, a better understanding of these biopolymers will aid in the use of such molecules in several fields of application in research and other high technologies, where they mimic functions of related biopolymers in living organisms.
