Process for producing tyres, tyres thus obtained and elastomeric compositions used therein

A process for producing a tyre for vehicle wheels, comprising:

• manufacturing a tyre comprising at least one crosslinkable elastomeric material;
• subjecting the tyre to moulding in a cavity defined in a vulcanization mould;
• crosslinking the at least one elastomeric material by heating the tyre to a predetermined temperature and for a predetermined time;
• wherein the at least one elastomeric material comprises:
• an elastomeric polymer comprising epoxide groups;
• and
• an oligomer of a fatty acid.

A tyre for a vehicle, comprising:

• a carcass structure;
• a belt structure;
• and
• a tread band;
• wherein the belt structure extends coaxially around the carcass structure,
• wherein the tread band extends coaxially around the belt structure,
• wherein the tread band comprises, externally, a rolling surface intended to come into contact with the ground,
• wherein the tread band further comprises an elastomeric polymer comprising epoxide groups crosslinked by reaction with an oligomer of a fatty acid.

A crosslinkable elastomeric composition, comprising:

• an elastomeric polymer comprising epoxide groups;
• and
• an oligomer of a fatty acid;
• wherein the composition is crosslinkable substantially in an absence of additional crosslinking agents.

A crosslinked elastomeric product obtained by crosslinking a composition comprising:

• an elastomeric polymer comprising epoxide groups;
• and
• an oligomer of a fatty acid;
• wherein the composition is crosslinkable substantially in an absence of additional crosslinking agents.
