Maleic anhydride (MAH) and N-vinylimidazole (NVIM) were found to form a charge transfer complex in 1,4-dioxane. The equilibrium constant, K, of the complex and its composition were calculated from the modified Benesi-Hildebrand equation by using UV spectrophotometry. Spontaneous copolymerization of MAH and NVIM has been studied in the range from 20 to 80 mol % MAH in the feed. The effects of the polymerization temperature, monomer feed composition, and total monomer concentration on the initial rate of polymerization were investigated. The values of overall activation energy, E-a, and overall order with respect to total monomer concentration were calculated. Copolymer compositions were found from the elemental analysis data. Reactivity ratios were calculated by the extended Kelen-Tudos method. (C) 1997 John Wiley & Sons, Inc.

SYNTHESIS OF A NEW ELECTROCHROMIC POLYMER BASED ON TETRAPHENYLETHYLENE CORED TETRAKIS CARBAZOLE COMPLEX AND ITS ELECTROCHROMIC DEVICE APPLICATION Carbas, Buket Bezgin; Odabas, Serhat; Turksoy, Figen; Tanyeli, Cihangir (2016-03-01) Poly-1,1,2,2-tetrakis(4-9H-carbazol-9-yl)phenyl)ethene P(TCP) was successfully synthesized by electrochemical oxidation of corresponding monomer, namely, 1,1,2,2-tetrakis(4-9H-carbazol-9-yl)phenyl)ethene (TCP) using dichloromethane as the solvent and tetrabutylammonium hexafluorophosphate (TBAPF(6)) as supporting electrolyte. Spectroelectrochemical properties of P(TCP) were investigated in situ recording the electronic absorption spectra of the polymer film coated on indium-tin oxide (ITO) at various potent...
Immobilization of catalase in poly(isopropylacrylamide-co-hydroxyethylmethacrylate) thermally reversible hydrogels Arica, MY; Öktem, Hüseyin Avni; Oktem, Z; Tuncel, SA (1999-09-01) Catalase was entrapped in thermally reversible poly (isopropylacrylamide-co-hydroxyethyl-methacrylate) (pNIPAM/HEMA) copolymer hydrogels. The thermoresponsive hydrogels, in cylindIl-rical geometry, were prepared in an aqueous buffer by redox polymerization. It was observed that upon entrapment, the activity retention of catalase was decreased between 47 and 14%, and that increasing the catalase loading of hydrogel adversely affected the activity. The kinetic behaviour of the entrapped enzyme was investigate...
Immobilization of tyrosinase in polysiloxane/polypyrrole copolymer matrices Arslan, A; Kiralp, S; Toppare, Levent Kamil; Yagci, Y (Elsevier BV, 2005-04-01) Immobilization of tyrosinase in conducting copolymer matrices of pyrrole functionalized polydimethylsiloxane/polypyrrole (PDMS/PPy) was achieved by electrochemical polymerization. The polysiloxane/polypyrrole/tyrosinase electrode was constructed by the entrapment of enzyme in conducting matrices during electrochemical copolymerization. Maximum reaction rate (V-max) and Michaelis-Menten constant were investigated for immobilized enzyme. Enzyme electrodes were prepared in two different electrolyte/sol vent sy...
AM1 treatment of some prostanoids Türker, Burhan Lemi (2002-10-31) Prostaglandins, PGD(2), PGE(2), PGH(2), PGI(2) and thromboxane TXA(2) which are all isomeric to each other were subjected to AM1(RHF) type quantum chemical treatment. PGI(2) was found to be the most stable and most exothermic of all the five, whereas PGH2 stands for the least stable and the least exothermic. Some calculated properties of these structures were also reported.
Thermal analysis of a new thiophene derivative and its copolymer Aslan, E.; Toppare, Levent Kamil; Hacaloğlu, Jale (2008-06-01) Thermal characteristics of a new thiophene derivative, 2-(thiophen-3-yl-)ethyl octanoate (OTE), its homopolymer (POTE), and copolymer with thiophene P(OTE-co-Th) were investigated via pyrolysis mass spectrometry. Thermal degradation of the copolymer started by lose of side chains and thiophene involving products evolved almost in the same temperature range where PTh degradation was detected, at slightly higher temperatures than PTh backbone decomposed during the pyrolysis of POTE. The extent of doping and n...
