AB  - Electrical AC conductivity of semiconducting low-density polyethylene (LDPE)-carbon black (CB) composites has been studied in the frequency range between 24 Hz and 75 kHz and the temperature range from 295 to 355 K. The composites were gamma irradiated at room temperature to different absorbed doses up to 300 kGy. The effects of gamma irradiation on the AC conductivity at room temperature and the conductive temperature coefficients (CTC) were observed. It was found that the effect of gamma irradiation on the stability of AC conductivity at elevated temperature (355 K) is dependent on the carbon black content and the gamma irradiation dose.

AB  - The surface dielectric properties of acid-etched low-density polyethylene (LDPE) were analysed in the frequency range from 20 Hz to 200 kHz. Samples were treated with various acids for a period of one hour, at temperatures ranging from 20 to 70 degrees C. After the treatment, the samples were analysed with Fourier transform infrared spectroscopy, revealing chemical and crystallinity changes on the surface, as a direct result of the treatment. The sample surfaces were analysed using atomic force microscopy. The micrographs show that the acid treatment increases the roughness of the samples. Compared to untreated LDPE, the etched samples may exhibit significantly different conductance values at low frequencies. It is also observed that an increase in the acid treatment temperature can result in lower values of conductance and susceptance compared to untreated samples. LDPE films with low value of surface AC conductivity after acid treatment are potentially useful substrates for high-speed electro-sensing applications. The presented results indicate that a suitable choice of acid treatment of LDPE can effect surface polarization while preserving low values of surface AC conductivity of the polymer.

AB  - Two types of polyethylene, low density (LDPE) and high density (HDPE), as well as low density polyethylene containing an antioxidant were subjected to gamma-irradiation in the presence of air and in water. The irradiated polymers were studied using IR spectrophotometric analysis. The radiation induced oxidative degradation was followed through the formation of oxygen containing groups by the development of bands in the 1850-1650 cm(-1) region and double bonds formation by the development of bands in the 1050-850 cm(-1) region. The crosslinking efficiency was determined by measuring the gel content by extraction with xylene. The radiation induced changes in the molecular structure, evolution of oxygen containing species and formation, of vinyl double bonds as well as of the crosslinking efficiency are discussed in terms of the properties of the polymers in an electric field of low strength.

AB  - The secondary crystallization of aged isotactic polypropylene (iPP) of different morphologies, which occurs during annealing in the vicinity of the melting temperature (140 degreesC), was studied using differential scanning calorimetry (DSC) and density measurements. The results of calorimetric and density measurements were correlated. Kinetics of the high temperature secondary crystallization (HTSC) was studied by using Avrami relations. Avrami exponents, obtained according to the increase in crystallinity after annealing at 140 degreesC, were considered as the measure of the ability of iPP to crystallize secondarily. Depending on the initial morphology of the samples, accelerated ageing influences in different ways the ability of iPP to subsequently crystallize upon annealing. The aged samples with larger amorphous content show a reduced secondary crystallization at high temperature compared with the unaged samples. On the other hand, aging of medium crystalline samples leads to more pronounced HTSC. (C) 2004 Elsevier Ltd. All rights reserved.

AB  - The effects of high concentrations of polar aluminum trihydrate (ATH) molecules on the dielectric relaxations of low-density polyethylene (LDPE) have been studied by dielectric loss (tan delta) measurements in the temperature range from 25 to 370 K. It was found that there are strong effects of polar ATH molecules on alpha and beta relaxation peaks, but no effect on the gamma relaxation peak, which is usually attributed to the localized conformational changes such as crankshaft or kink motion of the main chain in amorphous-phase surface layers of LDPE. Both strong alpha and beta peaks are shifted to lower temperatures with increasing concentration of ATH in the polymer. This behavior of alpha and beta dielectric relaxations of LDPE was related to the morphological changes in the amorphous and the crystal phase of highly doped semicrystalline polymer.

AB  - The influence of drawing, gamma irradiation and accelerated aging on the dielectric relaxation of low-density polyethylene has been studied using dielectric loss tangent measurements in the temperature range from 25 to 325 K and in the frequency range from 10(3) to 10(6) Hz. The intensity, position and activation energy of the gamma- and beta-dielectric relaxations were found to be strongly dependent upon the changes in the microstructure of the amorphous phase induced by uniaxial orientation, oxidation and crosslinking.

AB  - In thermosets and semicrystalline and/or amorphous thermoplastics, processing can result in internal molecular stress, which relieves on reheating (thermal history effects). The relief of these stresses appears as a small endothermic relaxation even after glass transition. Non reversing transitions in polymers also indicate the existence of thermal history effects. These effects can be modeled thereby improving interpretation of many experimental results. In this paper, a mathematical model for thermal history effects and heat flow in thermoplastics has been developed.

AB  - If a sample is exposed to the influence of laser radiation the part of its energy is absorbed and converted into heat. The heat, generated in this way, is transferred through the sample as heat waves, resulting in various effects (for example, photothermal effects). A large number of nondestructive diagnostic methods are based on recording of these effects. In a certain number of materials excited by laser pulses, such as complex biological materials, polymers, metal excited by very short laser pulses, etc., the property of thermal memory become significant. Starting with the hyperbolic equation that describes heat transfer processes of such media, we have developed a model of laser pulse-excited heat waves propagation in order to enable application of photothermal techniques in characterization of these media. The cases of optically opaque and transparent samples are considered. The influence of various backings on photothermal waves has also been analyzed. The results are compared to the previous models.

The influence of preparation conditions (quenching and annealing temperatures, annealing times and sample thickness), together with the measurement parameters (heating and cooling rates), on the iPP melting behaviour are analysed. The results reveal a constant yield of LMP crystals over a wide range of quenching temperatures. This study also suggests that the LMP alpha-crystals originate from the crystallization of polymer portions, which are somewhere between the amorphous and the smectic phase on the macromolecular scale of order.

AB  - Stress relaxation at room and elevated temperatures of high density (HDPE) and linear low-density polyethylene (LLDPE) has been investigated. Viscoelastic parameters (elasticity moduli and viscosity coefficients) of amorphous and crystal fraction at temperatures 18, 40, 60, 80 and 100 degreesC are determined by using two-process model for stress relaxation of polyethylene. The results show that amorphous viscosities of both polyethylene types clearly satisfy the Arrhenius dependence on temperature. Therefore, in the amorphous fraction of examined polyethylenes at elevated temperatures, there is a process with temperature independent activation energy. The estimated activation energies DeltaH approximate to 62.5 kJ/mol for LLDPE and DeltaH approximate to 59 kJ/mol for HDPE of that process are compared with activation energies determined from the time temperature superposition of experimental relaxation curves and with literature data.

AB  - Viscoelastic behavior at elevated temperatures of high-density polyethylene and isotactic polypropylene was investigated by using the stress relaxation method. The results are interpreted from the view of an established two-process model for stress relaxation in semicrystalline polymers. This model is based on the assumption that the stress relaxation can be represented as a superposition of two thermally activated processes acting in parallel. Each process is associated either with the crystal or amorphous phase of a polymer sample. It was found that the temperature dependence of viscosity coefficients and elastic moduli of these two fractions are similar in the two materials. The experimental data was correlated with literature data of alpha and beta processes in polyethylene and polypropylene obtained from dynamic mechanical thermal analysis.

AB  - The thermal stability of epoxy coatings electrodeposited on steel, phosphatized steel, steel electrochemically modified by Zn-Ni alloys and aluminium has been investigated. Epoxy coatings were formed by cathodic electrodeposition of epoxy adducts, using a constant voltage method. The rate of hydrogen evolution reaction in the polymer solution on different substrate surfaces was determined on Pt rotating disc using a slow sweep voltammetry. The characteristic thermal and thermooxidative degradation temperatures, as the measure of thermal stability, and activation energies of thermal degradation were determined by thermogravimetric analysis. It has been observed that different catalytic activities of substrates for H-2? evolution reaction give different rise to an increased amount of hydrogen bonds inside the polymer net and porosity of coating, strongly affecting the thermal and thermooxidative resistance of the polymeric material.

It is shown that stress improves progressively with increasing radiation dose for all the samples, but this effect is greatest for undrawn samples. The crystallinity has been studied by wide-angle X-ray diffraction (WAXD). Crystallinity has been found to increase with increasing draw ratio and radiation dose.
