FIELD: chemistry.

SUBSTANCE: method of radical polymerisation for obtaining the block-copolymers, in which at least one block represents the polymer block of the fluorinated vinyl monomer or monomers, in which used are: (A') one or several ethylene-unsaturated monomers and (B') one or several polymers of the fluorinated vinyl monomer or monomers, which includes the stages, in accordance with which (1'), at least, one part of (A') and, at least, one part of (B') are introduced into the reactor, and then (2') the content of the reactor interacts, while an optional (A') residue and optional (B') residue are introduced into it. The polymers of the fluorinated vinyl monomer or monomers (B') are selected from the polymers, obtained by the method of radical polymerisation to obtain polymers of the fluorinated vinyl monomer or monomers, in which used are: (A) one or several ethylene-unsaturated monomers, at least, one of which is selected from fluorinated vinyl monomers, (B) molecular iodine and (C) one or several radical-generating agents, selected from diazocompounds, peroxides and dialkyldiphenylalkanes. The method also includes the stages, in accordance with which (1), at least, a part of each of the compounds (A), (B) and (C) is introduced into the reactor, after which (2) the content of the reactor interacts, while the optional residue of each of the compounds (A), (B) and (C) is introduced in it, with further bringing stage (2) to completion.

EFFECT: elaboration of the effective method of radical polymerisation of halogenated monomers.
