Conducting polymers containing polyether pseudocages (PI, PII, PIII) have been synthesized via chemical oxidation of 1,5-bis(1,1-pyrrole)-3-oxabutane (MI), 1,8-bis(I,I-pyrrole)-3,6-dioxahexane (MII), and 1,11-bis(1,1-pyrrole)-3,6,9-trioxaundecane (MIII) using anhydrous FeCl3 in CHCl3. Because as obtained polymer resins did not give any response toward any cations, they were reduced (undoped) using chemical reducing agents. Tetrabutylammonium hydroxide was found to be more effective in undoping to obtain more reproducible and reusable polymer resins. The undoped polymer resins were tried in the extraction of rare earth metal ions from the aqueous medium. Among them, only PIII resin removes La(III), Eu(III) and Yb(III) and can be employed for the preconcentration of these metal ions. For batch extraction of La(III), Eu(III) and Yb(III) at neutral pH values, percent recoveries of 98.0 +/- 1.0, 90.7 +/- 1.4, 87.3 +/- 4.0, respectively, has been obtained. The sorption capacity is found as 1.3 mg of La(III) per gram of PIII resin. The PIII resin could be reused at least five times without significant change in its sorption capacity.

Thermal stability and decomposition mechanism of poly(p-acryloyloxybenzoic acid and poly(p-methacryloyloxybenzoic acid) and their graft copolymers with polypropylene, Part II
Cetin, S.; Tincer, T. (Wiley, 2008-04-05)
Thermal stability and decomposition mechanism of poly(p-acryloyloxybenzoic) acid (PABA), p-methacryloyloxybenzoic acid (PMBA), and their graft coproducts of PP were studied by differential scanning calorimetry, direct pyrolysis mass spectrometry, and TG/IR system, combined thermogravimetric analyzer, and FTIR spectrometer. The homopolymers and corresponding grafts were found to be stable in nitrogen atmosphere but started to decompose under atmospheric conditions when heated above 230 degrees C. PABA and PA...
Synthesis and characterization of poly(thiophen-3-yl acetic acid 4-pyrrol-1-yl phenyl ester-co-N-methylpyrrole) and its application in an electrochromic device
Bingol, B; Camurlu, P; Toppare, Levent Kamil (Wiley, 2006-05-05)
Copolymer of thiophen-3-yl acetic acid 4-pyrrol-1-yl phenyl ester (TAPE) with N-methylpyrrole (NMPy) was synthesized by potentiostatic electrochemical polymerization in acetotiitrile-tetrabutylammonium tetrafluoroborate solvent-electrolyte couple. The chemical structures were confirmed via Fourier transform infrared spectroscopy (FTIR), cyclic voltammetry (CV), and UV-vis spectroscopy. Electrochromic and spectroelectrochemical properties of poly(TAPE-co-NMPy) [P(TAPE-co-NMPy)] were investigated. Results sho...
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 a New Conducting Polymer Based on 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-phthalonitrile
Yavuz, Arzu; Bezgin, Buket; Önal, Ahmet Muhtar (Wiley, 2009-12-05)
A new conducting polymer was synthesized by electrochemical polymerization of 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-2-phthalonitrile (SNS-PN). Electrochemical polymerization of SNS-PN was performed in acetonitrile/0.2M LiClO4 solvent/electrolyte couple. Characterizations of the resulting polymer P(SNS-PN) were carried out by cyclic voltammetry, UV-vis, and Fourier transform infrared (FTIR) spectroscopic techniques. Spectroelectrochemical studies revealed that P(SNS-PN) has an electronic band gap of 2.45 eV...
Electropolymerization of a New 4-(2,5-Di-2-thiophen-2-yl-pyrrol-1-yl)-Tetra Substituted Nickel Phthalocyanine Derivative
Yavuz, Arzu; Carbas, Buket Bezgin; Aras, Leyla; Önal, Ahmet Muhtar (Wiley, 2011-10-15)
A new tetrakis 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl) substituted nickel phthalocyanine (NiPc-SNS) was synthesized and characterized by elemental analysis, Fourier Transform Infrared (FT-IR), and UV-vis spectroscopies. The electrochemical polymerization of this newly synthesized NiPc-SNS was performed in dichloromethane (DCM)/tetrabutylammonium perchlorate (TBAP) solvent/electrolyte couple. An insoluble film was deposited on the electrode surface, both during repetitive cycling and constant potential electr...
