Bifunctional living polytetrahydrofuran (PTHF) was terminated with potassium salt of pyrrole to yield polymers with electrochemically active end groups. These polymers were employed in the second stage to obtain conducting polypyrrole/polytetrahydrofuran block copolymers with short and long polytetrahydrofuran segments by potentiostatic anodic polymerization of pyrrole in different electrolytic media. Syntheses of block copolymers were achieved in media where tetrabutylammonium fluoroborate, sodium perchlorate and sodium p-toluenesulfonate were used as the supporting electrolytes. Characterizations were based on DSC, TGA, SEM, FTIR and CV analyses. No significant effect of the chain length of polytetrahydrofuran segments on the properties of the copolymers was observed; however, thermal, electrochemical behaviors, and surface morphologies of the films were greatly affected by the supporting electrolytes.

Synthesis of conducting PPy/pTHF copolymers Kizilyar, N; Toppare, Levent Kamil; Onen, A; Yagci, Y (Wiley, 1999-01-31) Living polytetrahydrofuran (pTHF) was terminated with the potassium salt of pyrrole to yield polymers with pyrrole end groups. Copolymerization of THF and pyrrole with short and long I,THF segments was achieved by constant potential electrolysis. Syntheses of the block copolymers were performed using tetrabutylammonium tetrafluoroborate, sodium pel:chlorate, and sodium p-toluenesulfonate as the supporting electrolytes. Characterization of the block copolymers were based on scanning electron microscopy, diff...
Crosslinked polymer gels for boron extraction derived from N-glucidol-N-methyl-2-hydroxypropyl methacrylate Bicak, N; Ozbelge, HO; Yılmaz, Levent; Senkal, BF (Wiley, 2000-03-24) Glycidyl methacrylate was reacted in 2-methyl pyrrolidone solution with N-methyl-D-glucamine (NMG) to produce N-D-glucidol, N-methyl-2-hydroxy propyl methacrylate (GMHP). The reaction proceeded exclusively via ring opening of the oxirane. The resulting vinyl monomer was a waxy product and soluble in water, ethanol, methanol, DMF, and NMP. Copolymerization of GMHP with N,N'-tetraallyl piperazinium dichloride by the inverse suspension method (water in oil), using a toluene/chloroform (3:1) mixture as continuo...
Poly(ethylene terephthalate)/Carbon Nanotube Composites Prepared With Chemically Treated Carbon Nanotubes Yesil, Sertan; Bayram, Göknur (Wiley, 2011-07-01) Surfaces of multiwalled carbon nanotubes (CNT) were functionalized by treatment with strong acid mixture (purification) followed by modification with sodium dodecyl sulfate, poly(ethylene glycol) (PEG), and diglycidyl ether of Bisphenol A (DGEBA). Poly(ethylene terephthalate) (PET)-based conductive polymer composites were prepared by using these CNT by means of melt mixing with a twin screw extruder. Amount of carboxylic acid groups on the CNT surface increased after acid treatment but decreased with surfac...
Synthesis of conducting block and graft copolymers with polyether segments Yagci, Y; Toppare, Levent Kamil (Wiley, 2000-07-01) Synthesis of block and graft copolymers containing polyether and conducting polypyrrole sequences were described. Pyrrole moieties were incorporated at the chain ends of polytetrahydrofuran and polysiloxane and at the side chains of polyethyl vinylether by ionic polymerization and appropriate chemical reactions. Subsequent electropolymerization with pyrrole through these moities yielded free standing films of the corresponding block and graft copolymers. The formation copolymers was evidenced by FTIR spectr...
Poly(dibromophenylene oxide)s Through Atom Transfer Radical Rearrangement Polymerization of Various Transition Metal Complexes ÇAMURLU, PINAR; Kisakuerek, Duygu (Informa UK Limited, 2009-01-01) In this study, the synthesis of poly(dibromophenylene oxide)s were achieved via atom transfer radical rearrangement polymerization through decomposition of Bis(2,4,6-tribromophenolato)di(N-methyl imidazole)Cu(II)-Cu(TBP)2(NMIZ)2, Bis(2,4,6-tribromophenolato)di(N-methyl imidazole)Co(II)-Co(TBP)2(NMIZ)2, Bis(2,4,6-tribromophenolato)di(N-methyl imidazole)Ni(II)-Ni(TBP)2(NMIZ)2 complexes. Polymerizations were carried out under two different conditions to investigate the effect of time and temperature on percent...
