Electroinitiated polymerization of acrylamide was carried out in acetonitrile–tetrabutylammonium fluoroborate by electrolytic reduction of monomer. It was shown by cyclic voltammetry that direct electron transfer from the cathode to the monomer can be achieved in this solvent–electrolyte system. Reduction peak potentials measured by cyclic voltammetry indicated that sodium salts will interfere with such a mechanism. Since the reduction peak potential of sodium salt and dimethylformamide are found to be lower than acrylamide, this couple was not employed for polymerization in this work. Acetonitrile–tetrabutylammonium fluoroborate couple is stable at the reduction peak potential of acrylamide.

Turac, Ersen; Varol, Ramazan; Ak, Metin; Sahmetlioglu, Ertugrul; Toppare, Levent Kamil (Informa UK Limited, 2008-01-01)
A new monomer, 4-(thiophen-3-yl methyleneamino)benzene sulfonate) (ThSA), was synthesized and characterized. Electrochemical polymerization of ThSA yields a water-soluble and self-doped polymer (PThSA). This polymer was characterized by FT-IR, NMR, DSC, XRD and conductivity measurements.

In this study, two new benzotriazole (BTz) and dithienothiophene (DTT) containing conjugated polymers were synthesized. After successful characterizations of the monomers by proton-nuclear magnetic resonance (1H NMR) and carbon-NMR (13C NMR) techniques, poly(4-(dithieno[3, 2-b:2,3-d]thiophen-2-yl)-2-(2-octyldodecyl)-2H-benzo[d][1,2,3] triazole) P1 and poly(4-(5-(dithieno[3,2-b:2,3-d]thiophen-2-yl)thiophen-2-yl)-2-(2-octyldodecyl)-7-(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole) P2 were synthesized via a typica...
Electrochromic performance and ion sensitivity of a terthienyl based fluorescent polymer
Atilgan, Nurdan; CİHANER, ATİLLA; Önal, Ahmet Muhtar (Elsevier BV, 2010-04-01)
A novel terthienyl based fluorescent polymer bearing strong electron-withdrawing substituents directly attached to the 3,4-positions of the central thiophene ring was synthesized by electrochemical polymerization of diethyl 2,5-di(3,4-ethylenedioxythiophen-2-yl)thiophene-3,4-dicarboxylate. The corresponding polymer was characterized by cyclic voltammetry, FT-IR and UV-vis spectroscopy. The polymer has a well-defined redox process (E-p,E-1/2 = 0.74 V) and demonstrates a reversible electrochromic behavior; li...
Conducting polymers of terepthalic acid bis-(2-thiophen-3-yl-ethyl) ester and their electrochromic properties
Coskun, Y; Çırpan, Ali; Toppare, Levent Kamil (Elsevier BV, 2004-07-12)
Terepthalic acid bis-(2-thiophen-3-yl-ethyl)ester (TATE) was synthesized through the reaction of 2-thiophen-3-yl-ethanol and terepthaloyl chloride. Homopolymer of TATE was synthesized via potentiostatic and potentiodynamic methods by using tetrabutylammonium tetrafluoroborate (TBAFB) as the supporting electrolyte in dichloromethane/borontrifluoride ethylether solvent mixture(DM/BFEE) (8:2, v/v). Copolymerisation of TATE with thiophene was achieved in DM/BFEE solvent mixture (8:2, v/v) by using TBAFB as the ...
Tin effect in formation and photocross-linking reactions of tri-n-butylstannyl methacrylate-allyl chloroacetate copolymer
Rzaev, ZMO (Wiley, 1998-09-30)
Radical-initiated copolymerization of tri-n-butylstannyl methacrylate (TBSM) with allyl chloroacetate (ACA) was carried out in the presence of benzoyl peroxide as initiator in benzene at 70 degrees C in nitrogen atmosphere. Monomer reactivity ratios of the TBSM (M-1)-ACA (M-2) monomer pair were determined by the Kelen-Tudos method: r(1) = 1.25 +/- 0.02 and r(2) = 0.13 +/- 0.005. From copolymerization kinetic data the Values of effective energy of activation (E-a) and orders with respect to initiator (n) and...
