Beschreibung
Zusammenfassung:	The invention provides an additive to silica-filled rubber composition comprising 1-20 wt % carbon nanotubes, 20-90 wt % of organosilane composition (S), and 5-70 wt % of organic rubber (R) soluble in organosilane composition (S). The technical result of the provided disclosure is decreasing electrical volume resistivity and simultaneously improving physical-mechanical properties of rubber, including elastic moduli, tear strength and others. A further important technical result of the provided disclosure is simplicity of the rubber mixing process and the possibility of industrial application of the provided methods in the standard technologies by substitution of a liquid organosilane coupling agent by a viscous paste-like additive provided by this invention. The invention provides also the method to produce the additive.
