Abstract
A 1,3-dipolar compound bearing at least a phosphorus-containing group and a dipole containing a nitrogen atom is provided. A method for grafting the 1,3-dipolar compound on an unsaturated polymer, a diene polymer comprising, along the polymer chain, at least one pendant phosphorus-containing group, and a rubber composition based on a diene elastomer and the 1,3-dipolar compound optionally pre-grafted on the diene elastomer are also provided. The 1,3-dipolar compound allows access to rubber compositions reinforced with an inorganic filler that have a compromise of improved properties, namely hysteresis, stiffness in the cured state and reinforcement.
