Book Synopsis Synthesis and Characterization of Poly(ionic Liquids) Derived from 1-ethyl-3-methyl-4-vinylimidazolium Triflate by : Darren M. Smith
Download or read book Synthesis and Characterization of Poly(ionic Liquids) Derived from 1-ethyl-3-methyl-4-vinylimidazolium Triflate written by Darren M. Smith and published by . This book was released on 2011 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the present research, 1-ethyl-3-methyl-4-vinylimidazolium trifluoromethane sulfonate (triflate) was synthesized and polymerized. For comparative purposes, 1-ethyl-3-vinylimidazolium triflate and its polymer was also prepared. Zwitterionic propane sulfonate derivatives of 1-methyl-5-vinylimidazole and 1-vinylimidazole were also synthesized and polymerized. Poly(1-ethyl-3-methyl-4-vinylimidazolium triflate) and poly(3-ethyl-1-vinylimidazolium triflate) were characterized by means of TGA, GPC, and DSC. The TGA showed that poly(1-ethyl-3-methyl-4-vinylimidazolium triflate) had a higher decomposition temperature range, 467-527oC, than poly(3-ethyl-1-vinylimidazolium triflate), 400-448oC. Poly(styrene) equivalent molecular weights were evaluated by GPC in DMF. Poly(1-ethyl-3-methyl-4-vinylimidazolium triflate) had a Mn = 13,000 g/mol (Mw = 14,500 g/mol, PD = 1.11) and poly(3-ethyl-1-vinylimidazolium triflate) had a Mn = 15,700 g/mol (Mw = 19,000 g/mol, PD = 1.21). Glass transition characteristics were evaluated by DSC. Poly(3-ethyl-1-vinylimidazolium triflate) exhibited an onset Tg of 127-129oC; that for poly(1-ethyl-3-methyl-4-vinylimidazolium triflate) was 115oC. The 1-vinylimidazolium triflate polymer was anion exchanged to create a family of polymers with anions consisting of (CN)2N-, (CF3SO2)2N-, BF4-, PF6-, AsF6-, CF3SO3-. This family of polymer salts was characterized by DSC and the lowest onset Tg 84oC, was exhibited by the (CF3SO2)2N- salt. In the salts with fluorinated anions of similar geometry, the larger the anion, AsF6-, exhibited an onset Tg of 119oC. The polymer with the smaller PF6- anion exhibited an onset Tg, of 172oC. A copolymer of 1-ethyl-3-methyl-4-vinylimidazolium triflate and 1-methyl-5-vinylimidazole was synthesized. This copolymer was also anion-exchanged to create a family of polymers with (CN)2N-, (CF3SO2)2N-, BF4-, PF6-, AsF6-, CF3SO3 anions. DSC analysis of this family of copolymers revealed a similar trend in onset glass transition temperatures to that observed with the poly(1-ethyl-3-vinylimidazolium) salts."--Abstract.

Download or read book Advances in Manufacturing and Characterization of Functional Polyesters written by Rafael Balart and published by MDPI. This book was released on 2021-06-10 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, we have assisted the remarkable growth in the use of functional polyesters. This book gathers novel research works dealing with the manufacturing and characterization of polyesters that have been functionalized by synthesis, copolymerization, additives (at micro- and nanoscale), surface modification, among other methodologies, to tailor desired properties in terms of mechanical, chemical, thermal, and barrier properties, biodegradation, and biocompatibility. Thus, Advances in Manufacturing and Characterization of Functional Polyesters will serve to guide a diverse audience of polymer scientists and engineers and provides an update of the “state-of-the-art” knowledge on functional polyesters.

Book Synopsis Bio-Based Plastics by : Stephan Kabasci
Download or read book Bio-Based Plastics written by Stephan Kabasci and published by John Wiley & Sons. This book was released on 2013-10-02 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of bio-based plastics has developed significantly in the last 10 years and there is increasing pressure on industries to shift existing materials production from petrochemicals to renewables. Bio-based Plastics presents an up-to-date overview of the basic and applied aspects of bioplastics, focusing primarily on thermoplastic polymers for material use. Emphasizing materials currently in use or with significant potential for future applications, this book looks at the most important biopolymer classes such as polysaccharides, lignin, proteins and polyhydroxyalkanoates as raw materials for bio-based plastics, as well as materials derived from bio-based monomers like lipids, poly(lactic acid), polyesters, polyamides and polyolefines. Detailed consideration is also given to the market and availability of renewable raw materials, the importance of bio-based content and the aspect of biodegradability. Topics covered include: Starch Cellulose and cellulose acetate Materials based on chitin and chitosan Lignin matrix composites from natural resources Polyhydroxyalkanoates Poly(lactic acid) Polyesters, Polyamides and Polyolefins from biomass derived monomers Protein-based plastics Bio-based Plastics is a valuable resource for academic and industrial researchers who are interested in new materials, renewable resources, sustainability and polymerization technology. It will also prove useful for advanced students interested in the development of bio-based products and materials, green and sustainable chemistry, polymer chemistry and materials science.

Book Synopsis Synthesis and Characterization of Thermotropic Liquid Crystalline Poly(ester-imide)s by : Jinseo Ahn
Download or read book Synthesis and Characterization of Thermotropic Liquid Crystalline Poly(ester-imide)s written by Jinseo Ahn and published by . This book was released on 1996 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A series of novel poly(ester-imide)s were prepared by the reactions of 6,6'-(3,3',4,4'-benzophenonetetracarboxylic diimido)-bis-hexanoic acid with various aliphatic diols containing four to ten methylene groups using a melt polymerization technique. Besides these, a novel poly(esterimide) was synthesized by the reaction of 1 1, 1 1 '-(3,3', 4,4'- benzophenonetetracarboxylic diimido)-bis-undecanoic acid with 1,6-hexanediol employing the same technique. Two kinds of monomers containing diimide diacids were prepared by the reactions of 3,3',4,4'-benzophenonetetracarboxylic dianhydride with respective 6-aminocaproic acid and 1 1 -aminoundecanoic acid. A total of eight poly(ester-imide)s, PEIMs, were characterized for liquid crystalline properties. The solubility, viscosity, infrared spectroscopy, thermal analyses such TGA and DSC, and the optical studies were performed. Infrared spectra of PEIMs confirmed the formation of imide and ester groups. These poly(ester-imide)s exhibited high thermal and oxidative stability and very poor solubility corresponding to high viscosity. There were no reproducible endothermic or exothermic peaks found besides glass transition temperatures in the DSC thermograms. In addition, no PEIMs showed birefringent textures under the polarized light microscope. DSC and optical study indicated that Odd PEIMs and PEIM(6,10) are totally amorphous, while Even PEIMs are partially crystalline polymers with extremely slow crystallization rate. Two new compounds, BTDI-1 1 A/1 8-ol and BPDI-1 1 A/1 8-ol, with small molecular weight were designed and synthesized. The reaction of respective BTDI-1 1 A and BPDI-1 1 A with 1 -octadecanol was performed in boiling toluene with azeotropic removal of water by using Dean-Stark apparatus. DSC and optical study with polarized light microscopy indicated that BTDI-1 1 A/1 8-ol has a liquid crystalline phase that is very close to solid crystal state, whereas BPDI-1 1 A/1 8-ol has no liquid crystalline property."--Abstract.
