Electroinitiated polymerization of butadiene sulfone was achieved by direct electron transfer in acetonitrile-tetrabutylammonium fluoroborate system by controlled potential electrolysis technique. High conversions were obtained at reasonable temperatures and polymerization times. The polymer was found to be composed of linear segments along with some cyclic units. The effect of monomer concentration, temperature, and polymerization potential on the rate of polymerization was investigated. Temperature and polymerization potential have positive effects on the rate of polymerization. The effect of ultrasonic vibration was also investigated by conducting electrolyses at different monomer concentrations in the presence and absence of ultrasonic vibration. It was observed that the rate of polymerization increases significantly in the presence of ultrasonic vibration. The inverse relationship between the rate of polymerization and monomer concentration was observed in presence and absence of ultrasonic vibration.

ELECTROINITIATED POLYMERIZATION OF ACRYLONITRILE
YURTTAS, B; Toppare, Levent Kamil; Akbulut, Ural (Informa UK Limited, 1988-01-01)
Anionic polymerization of acrylonitrile was achieved by constant-potential electrolysis via direct electron transfer to the monomer. The reduction peak potential in the (C4 H9)4 NBF4 -CH3 CN electrolyte-solvent system was measured by cyclic voltammetry. On the other hand, dimethylformamide-metal salts were not found suitable for the direct electron-transfer process in our system. Polymers produced both anodically and cathodically were found to contain cyclized structures.
ELECTROINITIATED POLYMERIZATION OF MALEIC-ANHYDRIDE BY DIRECT ELECTRON-TRANSFER
Akbulut, Ural (Wiley, 1991-02-01)
Controlled potential electrolysis was employed to accomplish homopolymerization of maleic anhydride, by direct electron transfer. The solvent used in the polymerization studies was acetonitrile-dimethylformamide mixture (1:1) with the supporting electrolyte tetrabutylammonium tetra fluoroborate. A brown paramagnetic polymer was obtained from the catholyte, upon electroreduction of monomer.
ELECTROINITIATED POLYMERIZATION OF ACROLEIN BY DIRECT AND INDIRECT ELECTRON-TRANSFER VIA CONTROLLED POTENTIAL ELECTROLYSIS
Toppare, Levent Kamil; Akbulut, Ural (Informa UK Limited, 1990-01-01)
Electroinitiated polymerization of acrolein has been achieved by controlled potential electrolysis at the reduction peak potential of the monomer for direct electron transfer. Kinetics and type of mechanism of the polymerization have been investigated. the structure of the polymer has also been examined by IR spectroscopy. in a separate experiment, a small amount of CCI4 was added to a polymerization system. Since the reduction peak potential of CCI4 appears at a more anodic region than that of acrolein on ...
Electrosynthesis of polyfuran in acetonitrile-boron trifluoride-ethyl ether mixture and its device application
Tirkeş, Süha; Önal, Ahmet Muhtar (Wiley, 2007-01-15)
Electrochemical polymerization of furan was achieved in acetonitrile/boron trifluoride/ethyl ether (CH3 CN/BF3/EE) mixture in the presence of tetrabutylammonium tetrafluoroborate via constant potential electrolysis at 1.4 V versus Ag/AgCl. Electrochemical behavior of furan was investigated in the same solvent mixture of varying ratios, utilizing cyclic voltammetry. Free-standing polyfuran (PFu) films were obtained in CH3CN/BF3/EE mixture (2/4/4; v/v/v) and characterized using FTIR spectroscopic technique. S...
Mass dispersion in transfer reactions with a stochastic mean-field theory
Washiyama, Kouhei; Ayik, Sakir; Lacroix, Denis (2009-09-01)
Nucleon transfer in symmetric heavy-ion reactions at energies below the Coulomb barrier is investigated in the framework of a microscopic stochastic mean-field theory. Although mean field alone is known to significantly underpredict the dispersion of the fragment mass distribution, a considerable enhancement of the dispersion is obtained in the stochastic mean-field theory. The variance of the fragment mass distribution deduced from the stochastic theory scales with the number of exchanged nucleons. Therefo...
