RUBBER MIXTURE AND PNEUMATIC TYRE Russian patent published in 2016 - IPC C08L15/00 C08L9/00 C08C19/25 C08C19/22 C08F230/08 C08F236/04 C08K3/36 B60C1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to rubber mixtures and pneumatic tyres made therefrom. Rubber mixture contains a conjugated diene polymer and silicon dioxide with specific surface area, measured from nitrogen adsorption from 40-400 m²/g. Conjugated diene polymer is obtained by polymerising a monomer component, including a conjugated diene compound and a silicon-containing vinyl compound, in presence of a polymerisation initiator. Then reaction with a compound containing a nitrogen atom and/or a silicon atom, with an active terminal group of copolymer. Amount of diene polymer from 1 to 90 wt%, amount of rubber based on polyisoprene from 0 to 70 wt %, each per 100 wt% of rubber component. Amount of silicon dioxide from 10 to 150 pts.wt per 100 pts.wt of rubber component.

EFFECT: invention enables to obtain a rubber mixture which enables to achieve balanced improvement of processability, fuel saving, strength of rubber, resistance to abrasive wear, grip with wet road surface and driving stability.
