Abstract
Process of controlled free-radical polymerization in aqueous dispersion for the preparation of a block copolymer at least one block of which is a block of a halogenated polymer using molecular iodine and at least one oxidant whose solubility in water is at least 10 g/l for the synthesis of the first block of the block copolymer.
