PHYSICO-MECHANICAL AND TRIBOLOGICAL PROPERTIES OF NANOCOMPOSITES AND THEIR VULCANIZATES ON THE BASIS OF MOLYBDENUM DISULPHIDE AND ETHYLENE-PROPYLENE BLOCK COPOLYMER

Institute of Polymer Materials, NAS of Azerbaijan *Sumgait State Technical College at Sumgait State University **V.A.Belyi Metal-Polymer Research Institute, NAS of Belarus najaf1946@rambler.ru Received 25.10.2018 The effect of the concentration and size of molybdenum disulphide fine particles on the breaking stress ultimate tensile stress, elongation at break, melt flow index and wear resistance of composite materials based on ethylene-propylene block copolymer and molybdenum disulphide is considered. The possibility of a significant improvement in the properties of nanocomposites by carrying out the crosslinking reaction in a dynamic mode is shown. Nanocomposites patterns of transition from solid to viscous state are investigated by thermomechanical analysis. The optimal concentrations of the reacting components have been established, at which the highest physicomechanical properties of nanocomposites are achieved
