Permeation of CO2 and O2 through a low density polyethylene film was studied with CO2-N2 MiXtures in the temperature range 263-283 K, and with CO2-O2-N2 mixtures in the range 257-313 K. The temperature dependence of the permeabilities of these gases agreed with the Arrhenius expression. The activation energy for carbon dioxide diffusion was between 3.53 x 10(4) and 3.74 x 10(4) J/mol; the activation energy for oxygen diffusion was 3.13 x 10(4) J/mol. The pre-exponential constant for oxygen was higher than that of carbon dioxide in various mixtures. It was also found that the pre-exponential constant of carbon dioxide decreased with increasing CO2 concentration in the mixtures.

DIPOLE-MOMENTS OF STYRENE 4-VINYLPYRIDINE COPOLYMERS .1. RELATION TO THE FRACTION OF POLAR COMPONENT YILMAZ, E; KUCUKYAVUZ, Z (Wiley, 1994-03-01) Mean-square dipole moments for styrene/4-vinylpyridine (S4VP) random copolymers were determined at five different temperatures, 25-60-degrees-C, in 1,4-dioxane solution. The dipole moment behaviour was examined with respect to the increase in mole fraction of the polar monomer, 4-vinylpyridine (4VP), in the copolymer. The behaviour observed was different from the general behaviour of similar copolymers.
Solution properties of polyaniline Yilmaz, Faris; Kucukyavuz, Zuhal (Wiley, 2010-04-01) Solution properties of polyaniline (PANI) synthesized at various temperatures were studied using static light scattering (SLS), intrinsic viscosity, and dynamic light scattering (DLS). We demonstrated that average radius of gyration (R-g), intrinsic viscosity [eta], and average hydrodynamic radius (R-H), of polyaniline molecules in dilute N-methyl-2-pyrrolidinone (NMP) solutions increased with decreasing synthesis temperatures, i.e.; increasing molecular weight. SLS data demonstrate that second virial coeff...
Electrochemical polymerization and characterization of polyether-substituted aniline derivatives Tirkeş, Süha; Oenal, Ahmet M. (Wiley, 2007-08-01) New compounds consisting of aniline units linked by polyether bridges have been synthesized and their electrochemical polymerization was performed via constant potential electrolysis and cyclic voltammetry in an aqueous solution containing 3.0 moI L-1 H2SO4. Chemical polymerization was carried out using (NH4)(2)S2O8 as oxidizing agent. It was found that both methods gave the same polymer product without any cleavage of the polyether bridge between aniline rings. The polymers were characterized using the Fou...
MODELING PERMEATION OF MODIFIED ATMOSPHERE GAS-MIXTURES THROUGH A LOW-DENSITY POLYETHYLENE PACKAGE FILM ILTER, M; OZILGEN, M; ORBEY, N (Wiley, 1991-01-01) Permeation of individual gases through a low density polyethylene package film with CO2-N2 and CO2-O2-N2 mixtures was simulated with a simple mathematical model. Permeabilities of carbon dioxide were of the order of 10(-12) m3/s m2atm/m with CO2-N2 systems. Including oxygen in the system did not change carbon dioxide permeabilities. Permeabilities of oxygen were of the order of magnitude of 10(-9) m3/s m2atm/m with this system. When a CO2-O2-N2 mixture was humidified no substantial change was observed i...
DIPOLE-MOMENTS OF ISOTACTIC AND ATACTIC POLY(PROPYLENE OXIDE) SAMPLES KUCUKYAVUZ, Z; ALYURUK, K; AHMAD, AM (Elsevier BV, 1991-01-01) Dipole moments of poly(propylene oxide) (PPO) samples with different tacticities were determined from dielectric constant and refractive index increment measurements, which were performed on dilute toluene and isooctane solutions. In contrast to previous reports, both refractive index increments and the dipole moment ratios showed a marked dependence on the tacticities of the samples. The dipole moment ratios of isotactic samples were greater than unity and decreased with increasing sequence concentration...
