Polymerization and characterization of 2-Hydroxyethyl acrylate Vargün, Elif; Usanmaz, Ali; Department of Polymer Science and Technology (2003) Poly(2-Hydroxyethyl acrylate), PHEA, is used as hydrophilic polymeric gels which have been studied because of its great importance for agricultural or biomedical applications. Biomedical applications of hydrogels include soft contact lenses, artificial corneas, soft tissue substitutes and burn dressings. In this study, it was aimed to synthesis the polymers with well-defined molecular weights, polydispersities and cahin topologies. Bulk, solution and atom transfer radical polymerization (ATRP) techniques at...

MONOMER REACTIVITY RATIOS OF STYRENE-4-VINYLPYRIDINE COPOLYMERS AT LOW AND HIGH CONVERSIONS YILMAZ, E; KUCUKYAVUZ, Z (Elsevier BV, 1993-01-01) Monomer reactivity ratios in free-radical copolymerization of styrene and 4-vinylpyridine monomers at 80-degrees-C in toluene solution under reduced pressure were determined for low and high conversions. Finemann-Ross, Kelen-Tudos, extended Kelen-Tudos and Mayo-Lewis methods were used for this purpose. The most reliable method was found to be the extended Kelen-Tudos method. By the use of this method, for conversions below 20%, monomer reactivity values of 0.700 +/- 0.005 and 0.335 +/- 0.001 were calculated...

Pyrolysis mass spectrometric analysis of copolymer of polyacrylonitrile and polythiophene Oğuz, Gülcan; Hacaloğlu, Jale; Department of Polymer Science and Technology (2004) In the first part of this work, the structural and thermal characteristics of polyacrylonitrile, polyacrylonitrile films treated under the electrolysis conditions in the absence of thiophene, polythiophene and the mechanical mixture and a conducting copolymer of polyacrylonitrile/polythiophene have been studied by pyrolysis mass spectrometry technique. The thermal degradation of polyacrylonitrile occurs in three steps; evolution of HCN, monomer, low molecular weight oligomers due to random chain cleavages a...
