RUBBER MIXTURE AND TYRE MADE THEREFROM Russian patent published in 2013 - IPC C08L9/00 C08L21/00 B60C1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a rubber mixture and a tyre made from the rubber mixture. The rubber mixture is characterised by compounding of more than 1 pts.wt but less than 30 pts.wt of a low-molecular weight polymer component (B), having content of a bound aromatic vinyl compound of 0 wt % and average molecular weight with respect to polystyrene of 0.2×10⁴-8.0×10⁴, and 5-80 pts.wt filler (C) per 100 pts.wt of a high-molecular weight polymer component (A), having content of a bound aromatic vinyl compound of 0 wt % and average molecular weight with respect to polystyrene of at least 1.5×10⁵. Content of the bound aromatic vinyl compound (S₂) (wt %) in the low-molecular weight polymer component (B) and content of vinyl links (V₂) (%) in a part of a conjugated diene compound in the low-molecular weight polymer component (B) satisfies the relationship S₂+V₂/2<25 (I).

EFFECT: invention provides excellent processing of the rubber mixture, improves the dynamic modulus of elasticity (G') and loss tangent (tanδ) at low temperature and improves wear-resistance of the tyre.
