FIELD: polymers, in particular rubber compositions. ^ SUBSTANCE: claimed sulfur curable composition filled with silica and/or silicate contains (per 100 pts of rubber): silica and/or silicate 20-100 pts; silane binding agent as modifier of silica or silicate 1.6-8 pts; antiaging agent 0.05-5 pts; curing accelerant 0.1-5 pts; sulfur or sulfur donor 0.1-10 pts; and quinonediimine 0.5-5 pts, with the proviso, that antiaging agent is not quinonediimine. Invention also relates to method for curing which includes mixing and heating of abovementioned rubber composition at 110-200°C for up to 12 h; as well as industrial article such as pneumatic tire containing rubber cured stock obtained as described above. ^ EFFECT: composition of accelerated curing time, improved abrasion resistance, viscoelastic properties, aging characteristics, etc. ^ 10 cl, 6 tbl |
