    摘要： The present invention relates to a tyre comprising at least one structural element including a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition comprising: (a) 100 phr of at least one elastomeric polymer; (b) from about 0.1 phr to about 120 phr of at least one reinforcing filler; (c) from about 0.01 phr to about 20 phr of at least one oxetane derivative; and (d) from about 0.01 phr to about 10 phr of at least one carboxylic acid. Preferably, said structural element is selected from: tread band, tread underlayer, bead filler, sidewalls, and sidewall inserts.

    摘要： 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.

    摘要： Tyres for vehicle wheels having reduced environmental impact and the components thereof, in particular reinforcing structural elements such as carcass structures, belt structures, flippers and chafers, include elongated reinforcing elements treated with resorcinol and formaldehyde-free cross-linkable adhesive compositions. The adhesive compositions include at least a) a rubber latex, at least b) an epoxide and at least c) a polyamine with molecular weight higher than 190 Daltons, including at least two amino groups selected from primary —NH2 and secondary —NH— amino groups. In the structural element, these compositions confer an adhesion between cords and compounds that is comparable to, if not better than, the traditional RFL system in use in this sector. Furthermore, by suitably modifying the compound compositions in the reinforced structural elements and, possibly, also in the other elastomeric components of the tyre, it is possible to manufacture tyres while avoiding the use of toxic chemicals, such, as resorcinol and formaldehyde.
