FIELD: polymer production.
SUBSTANCE: invention provides a method for preparing block copolymer constituted by units [A][B], where A represents polymer block consisting of radical polymerization-capable monomer and B represents polysiloxane block. Method comprises two-step polymerization of monomer in presence of atom-transferring radical-type initiator to form polymer functionalized with a terminal leaving group capable of being replaced by nucleophilic terminal groups of polysiloxane. The latter step results in formation of block copolymer [A][B].
EFFECT: optimized synthesis strategy.
