FIELD: chemistry.SUBSTANCE: vulcanisable rubber composition contains an elastomer; reinforcing filler selected from silicon dioxide, technical carbon and mixtures thereof; a curing agent and aminoalkoxy-modified silsesquioxane (AMS), which contains one or more compounds selected from a group consisting of amino-AMS, amino/mercaptan-with-AMS, amino/(blocked mercaptan)-with-AMS, mixtures thereof and solid compounds and aqueous solutions, neutralised with a weak acid. Also disclosed is a pneumatic tyre made from the disclosed vulcanisable rubber composition.EFFECT: adding AMS to the rubber composition endows the vulcanisable rubber composition with improved dynamic viscoelastic and mechanical properties owing to improved dispersion of the reinforcing filler, and improves processability of the rubber composition.13 cl, 6 tbl, 5 ex |
