Abstract:<\/p>\n

Using wide-angle X-rays scattering method, differential scanning calorimetry and methods of thermo-mechanical analysis some structural and thermal properties of PE-80 and PE-100 polyethylene samples and their hot tool butt welds have been investigated. It was defined that the welded joint of two dissimilar types of polyethylene the structure of which is characterized by recrystallization of the crystalline phase. It is shown that the strength and thermal stability of the welded joint material are higher comparing to these properties of the initial materials; this can be explained texturing of polyethylene microstructure in the welded joint.<\/em><\/p>\n
