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.
