Zusammenfassung:	FIELD: rubber-processing industry, more particularly rubber compositions with antioxidants. SUBSTANCE: rubber composition comprises (wt parts): natural rubber, 100; sulfur, 1.25-1.5; vulcanization accelerator, 0.8-1.0; zinc oxide, 5.0; stearic acid 1.5; industrial carbon 40-45; butylamine based mixture, 1.0- 2.5. Antioxidant is butylamine based mixture. The latter is prepared by alkylation of aniline with n-butyl alcohol. EFFECT: improved thermooxidative stability of the rubber composition. 7 ex, 3 tbl
