A process for manufacturing a masterbatch comprises the following steps: (a) bringing at least one initial polymer comprising at least one carbon-carbon unsaturation into contact with at least one 1,3-dipolar grafting agent bearing at least one nitrile oxide dipole in the presence of at least one organophosphorus additive selected from the group consisting of phosphoric acid triesters, phosphonates, phosphinates, phosphine oxides and the mixtures of these compounds, and (b) recovering the masterbatch obtained in the preceding step. The masterbatch and compositions containing it and also tires comprising such compositions are also disclosed.
