Diene polymer modified by an epoxide group

Abstract

A diene polymer including at least one specific epoxide side group, one of the carbon atoms of which simultaneously has an attachment to the polymer chain and is a trisubstituted carbon, and the other carbon atom is an at least trisubstituted carbon is provided. The introduction of such a polymer, in particular elastomer, into a rubber composition makes it possible to improve its rupture properties without this being at the expense of its hysteresis properties, while at the same time improving its implementation.
