Radical polymerization process for the preparation of halogenated polymers, using one or more ethylenically unsaturated monomers, at least one of which is chosen from halogenated monomers, molecular iodine and one or more radical-generating agents chosen from diazocompounds, peroxides and dialkyldiphenylalkanes. Radical polymerization process for the preparation, starting from the halogenated polymers prepared by the process as described above, block copolymers of which at least one block is a block of halogenated polymer. Halogenated polymers which have a number-average molecular mass Mn greater than 1.0 104 and a polydispersity index MW / Mn less than 1. 60. Block copolymers at least one block of which is a block of halogenated polymer identical to halogenated polymers described above. |
