Summary:Process for the manufacture of copolymers with magnetic properties, including a first stage of copolymerisation by oxidation in acidic medium of a first monomer chosen from optionally substituted aniline and of a second monomer chosen from substituted aminoaromatic compounds, which comprises: - an induction stage during which the first monomer is brought into contact with at least one oxidising agent and at least one initiating agent, - and a production stage during which, after the introduction of the second monomer, at least one oxidising agent and at least one initiating agent are gradually added.
