Permeabilities of cast films of methylmethacrylate-co-methacrylic acid (MMA-MAA) and its 5% neutralized Na1+, Cs1+, Zn2+, Ba2+, and Al3+ ionomers for urea, sodium chloride, and creatinine were determined using a double (donor and acceptor) compartment cell. Film permeability was increased as the ionic potential decreased and it was more marked with urea as compared with sodium chloride and creatinine. Tensile properties of the above samples were also tested and variations in Young's Moduli were based on the effect of type of aggregates produced by the cations in the matrix of the copolymer.

Synthesis of N-polyethereal polypyrroles and their application for the preconcentration of rare earth ions
Koksel, Bahar; CİHANER, ATİLLA; Kaya, Murat; Volkan, Mürvet; Önal, Ahmet Muhtar (Wiley, 2008-05-15)
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 mor...
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...
Enzyme electrodes for determination of total phenolic capacity of red wines
KIRALP, S; Çırpan, Ali; Toppare, Levent Kamil (Wiley, 2005-10-05)
A tyrosinase-modified electrode, based on physical entrapment of enzyme in copolymer matrix of decanedioic acid bis(4-pyrrol-1-yl-phenyl) ester (DAPE) with pyrrole was constructed and used to investigate the total amount of phenolics in red wines. Kinetic parameters, V-max, and K-m, were determined. Also, temperature, pH optimizations, operational stability and shelf life of the enzyme electrode were examined. Surface morphologies of the films were studied by scanning electron microscope. (c) 2005 Wiley Per...
Effect of Carbon Nanotube Purification on the Electrical and Mechanical Properties of Poly(ethylene terephthalate) Composites with Carbon Nanotubes in Low Concentration
Yesil, Sertan; Bayram, Göknur (Wiley, 2011-03-15)
Surface properties of carbon nanotubes (CNTs) were altered by purification with nitric acid, sulfuric acid, ammonium hydroxide, and hydrogen peroxide. As-received and purified CNT-based conductive poly( ethylene terephthalate) composites were prepared with a twin-screw extruder. The effects of CNT purification on the surface properties of the CNTs and on the morphology and electrical and mechanical properties of CNT-based composites were investigated. Surface energy measurements showed that the acidic compo...
Side-chain functionalization of polystyrene with maleic anhydride in the presence of Lewis acids
Kurbanova, RA; Mirzaoglu, R; Akovali, G; Rzaev, ZMO; Karatas, I; Okudan, A (Wiley, 1996-01-10)
Polystyrenes with different molecular weights were chemically modified with maleic anhydride by use of certain cationic catalysts of Lewis acid type (BF3 . OEt(2), AlCl3, TiCl4, ZnCl2, FeCl3, and SnCl4) in chloroform. The effects of molecular weight of polystyrene, as well as type of Lewis acid used, on properties and structure of products were investigated. The interrelation between the molecular weight of polystyrene and content of carboxyl groups in the products was made. A direct relationship between th...
