Abstract
The present invention relates to compositions for elastomeric compounds for tyres, comprising polytetrazole cross-linking compounds characterized by precise activation temperatures, tyre components and tyres for vehicle wheels which comprise them. Advantageously, the present polytetrazole cross-linking agents give lower hysteresis and retention of the modulus of the compounds even under stress.
