Summary: | The present invention relates to new antioxidant and antiozonant elastomeric compositions for tyres, characterized by reduced volatility of the active compounds, improved processability and environmental sustainability, increased anti-degradation efficacy and improved surface appearance. In particular, the elastomeric compositions of the inventions comprise Salts formed by acids AC of formula (I) and amines AM of formula (II) The elastomeric compositions of the inventions are particularly suitable for the manufacture of tyre components such as sidewalls, treads and anti-abrasive layer, components that in the tyre are particularly subject to wear due to the combination of the degrading action of ozone and mechanical stresses. |
