The results of modification of the compositions of the rubber compound IRP 1078, HNBR-containing, with molybdenum disulphide and submicrometer graphite were presented. Improvement of the tribological properties was the aim of the modification. It was found that each of this modifiers don?t give a significant improvement of the coefficients of friction and the temperature rises cause by friction. Using of the numerical approximation method (polynomial second degree) the range of the modifiers contents was found in which a synergism of this modifiers gives considerably improvement of the tribological properties of the vulcanizates.
