The possibility is shown of increasing the hardness and wear resistance of crystallising polyolefins by introducing a highly dispersed (<1 μm) additive – molybdenum disulphide (0.1–10.0 vol%) – into the polymers. The wear resistance of the polymeric materials depends on the degree of crystallinity of the polyolefins, the hardness of the composites, and also the formation of boundary lubricating layers of molybdenum disulphide.
