This paper presents the results of a study of the effect of functional fillers on the properties and structure of ultra-high molecular weight polyethylene (UHMWPE). 2-Mercaptobenzthiazole (MBT), diphenylguanidine (DPG), tetramethylthiuram disulfide (TMTD) and sulfenamide (CBS) were used as functional additives. The concentration of fillers in UHMWPE was 0.5, 1 and 2 wt.%. It has been established that the introduction of functional additives significantly increases the tensile strength characteristics of the initial polymer. Thus, the maximum increase in tensile strength is observed with the introduction of TMTD and DPG, which showed an increase of 44% and 41% compared to the original UHMWPE, respectively. Relatively high wear resistance is observed in composites containing MBT and CBS. The effectiveness of the use of functional additives as UHMWPE modifiers is shown.
