The paper presents results of the investigation of structure relaxation and thermal properties of PE-80 and PE-100 polyethylene hot-tool butt welds. It was found that a weld with the re-crystallized crystalline structure is formed during the welding of dissimilar types of polyethylene. It is shown that within a long period (1 year) the relaxation occurs not only in amorphous but also in the cry...
Liquid-crystalline nanoparticles represent an exciting class of new materials for a variety of potential applications. By combining supramolecular ordering with the fluid properties of the liquid-crystalline state, these materials offer the possibility to organise nanoparticles into addressable 2-D and 3-D arrangements exhibiting high processability and self-healing properties. Herein, we revie...
The glass properties and semi crystalline properties of polymers are observable by X-ray diffraction. Some previous works 1, 2, 3 were about determination of degree of crystallinity of sPS by various technologies, like for example DSC, XRD and Raman spectroscopy. The purpose of this paper is to show importance of Raman spectroscopy as analytical tool for the study of amorphous and semi-crystall...
