Abstract
A 1,3-dipolar compound including an epoxide group is provided. The epoxide group is a 3-membered ether ring in which a first member is a carbon atom having an attachment to the dipole of the 1,3-dipolar compound and a second member is a tertiary or quaternary carbon. The use of the 1,3-dipolar compound in the modification of a diene polymer makes it possible to improve the rupture properties of a rubber composition comprising the modified polymer, without the expense of its hysteresis properties, while at the same time improving its implementation.
