The present invention relates to a1, 3-dipole compound bearing at least one phosphorus-containing group and a dipole of a nitrogen atom, to a process for grafting a1, 3-dipole compound to an unsaturated polymer, to a diene polymer comprising at least one phosphorus-containing side group along the polymer chain, to a rubber composition based on a diene elastomer and a1, 3-dipole compound, optionally pre-grafted to a diene elastomer. The 1, 3-dipolar compound allows to obtain rubber compositions reinforced with inorganic fillers, having an improved compromise of properties, namely hysteresis, stiffness in the cured state and reinforcing properties. |
