Trimethylene Carbonate and epsilon-Caprolactone Based (co)Polymer Networks: Mechanical Properties and Enzymatic Degradation
Bat, Erhan; Harmsen, Martin C.; van Luyn, Marja J. A.; Zhang, Zheng; Grijpma, Dirk W.; Feijen, Jan (American Chemical Society (ACS), 2008-11-01)
High molecular weight trimethylene carbonate (TMC) and epsilon-caprolactone (CL) (co)polymers were synthesized. Melt pressed (co)polymer films were cross-linked by gamma irradiation (25 kGy or 50 kGy) in vacuum, yielding gel fractions of up to 70%. The effects of copolymer composition and irradiation dose on the cytotoxicity, surface properties, degradation behavior, and mechanical and thermal properties of these (co)polymers and networks were investigated. Upon incubation with cell culture medium containin...
Heterpolyacid catalysts for etherification of isoolefins
Obalı, Zeynep; Doğu, Timur; Department of Chemical Engineering (2003)
Due to the water pollution problems created by MTBE, significant research was focused on the production of alternative oxygenates, such as ethyl tert-butyl ether (ETBE), tert-amyl-methyl-ether (TAME) and tert-amyl-ethyl-ether (TAEE) as octane enhancing gasoline blending components. These oxygenates are expected to improve the burning characteristics of gasoline and reduce exhaust emissions of CO and hydrocarbons. Generally, macroreticular acidic resin catalysts (Amberlyst-15) are used for the etherification...
Polyaniline: synthesis characterization solution properties and composites
Yılmaz, Faris; Küçükyavuz, Zuhal; Department of Polymer Science and Technology (2007)
Polyaniline was chemically synthesized at three different temperatures of 25, 0, and -25oC, by oxidative polymerization with ammonium peroxidisulfate at equimolar of aniline to oxidant ratio and 1M HCl. The resulted polyaniline was in a powder form which was characterized by several techniques such as: electrical conductivity, elemental analysis, thermal analysis, wide-angle X-Ray diffraction, and scanning electron microscope. The solution properties of the reduced polymer were studied by viscometry, static...
Dimethyl ether, diethyl ether & ethylene from alcohols over tungstophosphoric acid based mesoporous catalysts
Ciftci, Aysegul; VARIŞLI, DİLEK; Tokay, Kenan Cem; Sezgi, Naime Aslı; Doğu, Timur (2012-10-01)
Tungstophosphoric acid (TPA) incorporated silicate structured new mesoporous catalysts were synthesized following one-pot hydrothermal and impregnation procedures. Surface area of TPA@MCM-41, which was prepared by impregnating TPA into MCM-41, was two orders of magnitude higher than the surface area of pure TPA and this catalyst showed very high activity in dehydration reactions of both ethanol and methanol. Ethanol fractional conversion values reaching to 1.0 was obtained at 300 degrees C at a space time o...
Hetero Diels-Alder reactions of acyl phosphonates: synthesis of glycosyl type phosphonates
Polat-Cakir, Sidika; Demir, Ayhan Sıtkı (Elsevier BV, 2011-04-01)
We have prepared glycosyl type phosphonates via hetero Diels-Alder (HDA) reactions of acyl phosphonates with electron rich dienes. HDA reactions of acyl phosphonates with Danishefsky's diene required thermal activation to yield the desired dihydropyranones in good yield (70-91%). The reactions with Brassard's diene involved Lewis acid promotion to yield the corresponding lactones, though in moderate yield (33-69%).
