FIELD: chemistry.
SUBSTANCE: invention relates vulcanised rubber and a method for production thereof. The method of producing vulcanised rubber includes a first step of mixing S-(3-aminopropyl)thiosulphuric acid and/or a metal salt thereof, a rubber component, filler and a sulphur component to obtain a mixed product, where the sulphur component is powdered sulphur, precipitated sulphur, colloidal sulphur, insoluble sulphur or highly dispersed sulphur, and a second step for heat treatment of the mixed product obtained at the first step, where temperature during heat treatment is in the range of 120 to 180°C.
EFFECT: obtained vulcanised rubber is suitable for use in making tyre treads having improved viscoelastic properties.
