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 in CO2 permeability, but the O2 permeability decreased almost 10 times. These results and the mathematical model presented may help in the modified atmosphere package design to increase the shelf life of produce.

TEMPERATURE EFFECTS ON PERMEATION OF MODIFIED ATMOSPHERE GAS-MIXTURES THROUGH A LOW-DENSITY POLYETHYLENE PACKAGE FILM
TOKATLI, K; OZILGEN, M (Wiley, 1993-01-01)
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 t...
Synthesis and characterization of thiophene functionalized polystyrene copolymers and their electrochemical properties
Sahin, E; Camurlu, P; Toppare, Levent Kamil; Mercore, VM; Cianga, I; Yagci, Y (Wiley, 2005-12-01)
Thiophene functionalized polystyrene samples (TFPS) were synthesized by atom transfer radical polymerization (ATRP) of styrene, followed by Suzuki coupling with 3-thiophene (Th) boronic acid. Conducting graft polymer of TFPS with thiophene was achieved at 1.5 V in tetrabutylammonium tetrafluoroborate/dichloromethane (TBAFB/DM) by electrochemical methods. Spectroelectrochemical analysis of the resulting copolymers [P(TFPS-co-Th)] reflected electronic transitions at 449, 721 and 880 nm, revealing pi - pi* tra...
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...
LATTICE POLYMERS - BEHAVIOR FAR FROM THETA-CONDITIONS
YURTSEVER, E; ISSEVER, S (Elsevier BV, 1992-01-01)
Two-dimensional Monte-Carlo simulations of lattice polymers were carried out employing Lennard-Jones (LJ) type intramolecular interactions. The shape-dependent properties of these polymers were studied over a large range of interaction parameters and temperatures. The variation of the critical constant was also analysed. Two-dimensional surfaces of sections were used to determine the portions of the parameter space which corresponded to theta-conditions. The behaviour of LJ polymers far from theta-condition...
Properties of blends prepared from surface-modified low-density polyethylene and poly(vinyl chloride)
Akovali, G; Torun, TT (Wiley, 1997-03-01)
Improvement of adhesion between low-density polyethylene (LDPE) and poly(vinyl chloride) (PVC) in their blends was attempted by plasma modification of their surfaces. A series of different plasma treatments, vinyl chloride or carbon tetrachloride plasma for PE and acetylene plasma for PVC, were employed. In addition, an oligomeric copolymer of PE-VC was also tested in the blend. After modification, different degrees of improvement were obtained in mechanical properties, ranging from slight for acetylene pla...
