A novel synthesis of poly(dichlorophenylene oxide) and a conducting polymer were achieved simultaneously from 2,4,6-trichlorophenol in a very short time, using microwave energy. The characterizations of poly(dichlorophenylene oxide) and the conducting polymer were performed by DSC, TGA, elemental analysis, FTIR, H-1 and C-13 NMR, SEM, MS and X-ray diffraction spectrometer analyses. The combined molecular weight of the polymer, 1.8 x 10(4), was determined by using viscometry measurement. Poly(dichlorophenylene oxide) displaces selectivity in the favor of mainly 1,2-addition structure. The optimum conditions for the polymer and the conducting polymer synthesis were 70 W for 5 min and 100 W for 1 min, respectively. The direct synthesis of highly conducting polymer, with the conductivity of 0.3 S cm(-2) were achieved in the absence of applied doping process in a very short time sequence. Conductivity-temperature relation was examined for the conducting polymer. (C) 2004 Published by Elsevier Ltd.

Synthesis and characterization of alternating copolymers of thiophene-containing N-phenyl maleimide and styrene by photoinduced radical polymerization and their use in electropolymerization Yilmaz, F; Cianga, L; Guner, Y; Topppare, L; Yagci, Y (Elsevier BV, 2004-08-05) A novel N-(4-(3-thienyl methylene)-oxycarbonylphenyl) maleimide (MBThi) monomer was synthesized by the esterification reaction of maleimidobenzoic acid (MBA) with 3-thiophene methanol. Photoinduced radical polymerization was employed to prepare the alternating copolymers of MBThi with styrene (St) at room temperature using omega,omega-dimethoxy-omega-phenylacetophenone (DMPA) as photoinitiator. Different copolymerization conditions were examined to estimate the influence of the used solvents and comonomers'...
Synthesis, characterization and electrochromic properties of a conducting copolymer of pyrrole functionalized polystyrene with pyrrole Tarkuc, S; Sahin, E; Toppare, Levent Kamil; Colak, D; Cianga, I; Yagci, Y (Elsevier BV, 2006-03-08) A well-defined polystyrene (PSt) based polymer containing at one end-chain 3.5-dibromobenzene moiety. prepared by atom transfer radical polymerization (ATRP), was modified in two reaction steps. First one constitutes a Suzuki coupling reaction between aromatic dibromine functional polymer and 3-aminophenylboronic acid, when a diamino-containing intermediate was obtained. The second step is a condensation reaction between the diamino functional polystyrene and 2-pyrrole alclehyde. Thus, a polymer containing ...
Microwave-Assisted Simultaneous Synthesis of Conducting and Non-Conducting Polymers from Potassium 2,4,6-Tribromophenolate Celik, Gueler Bayrakli; Kisakurek, Duygu (Springer Science and Business Media LLC, 2009-01-01) A simultaneous synthesis of white poly(dibromophenylene oxide) (P) or yellow radical ion polymer (RIP) and black conducting polymer (CP) were achieved from potassium 2,4,6-tribromophenolate by microwave energy in a very short time. Polymerizations were carried out (i) under constant microwave energy and constant amount of water with different time intervals ranging from I to 7 min or (ii) at constant time intervals and constant amount of water with variation of microwave energy ranging from 70 to 900 watt o...
Synthesis and characterization of poly(allyl methacrylate) obtained by gamma-radiation Vardareli, Tugba K.; Usanmaz, Ali (Wiley, 2007-04-15) Allyl methacrylate was polymerized by gamma-radiation under vacuum in solution and atom transfer radical polymerization (ATRP) methods and also in the presence of atmospheric oxygen in bulk. The kinetic curve is S-type with a longer induction period, because of the presence of oxygen, in bulk polymerization. The curve for the solution polymerization is almost linear with a short induction period. The rate started to decrease after about 60% conversion and reached to a limiting conversion of 100%. The polyme...
Synthesis and Characterization of 2-Hydroxyethyl Methacrylate (HEMA) and Methyl Methacrylate (MMA) Copolymer Used as Biomaterial Vargun, Elif; SANKIR, MEHMET; Aran, Bengi; DEMİRCİ SANKIR, NURDAN; Usanmaz, Ali (Informa UK Limited, 2010-01-01) A series of poly(methyl methacrylate-co-hydroxyethyl methacrylate) (PMMA-co-PHEMA), copolymers were synthesized by an emulsion polymerization technique. Copolymer compositions were determined by FT-IR and 1H-NMR spectroscopy. It was found that comonomer ratios used in the recipes were comparable within the actual copolymers. Glass transition temperatures (Tg) of PMMA-co-PHEMA copolymers were varied from 119 degrees C to 100 degrees C by increasing HEMA content. Thermogravimetric analysis showed that the cop...
