Abstract
A rubber composition based on at least one diene elastomer, a reinforcing filler and a 1,3-dipolar compound comprising an epoxide group is provided. The epoxide group is a 3-membered ether ring in which a first member is a carbon atom exhibiting a connection to the dipole of the 1,3-dipolar compound and a second member is a tertiary or quaternary carbon. Such a rubber composition exhibits improved properties at break and an improved processing, as well as good hysteresis properties.
