FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing block-copolymers which contain a reactive functional group. Described is a method of producing a block-copolymer, involving: a) reaction of an acrylic monomer, having functional groups which are epoxy, acid, anhydride, amine, amide and hydroxy groups, and one or more vinyl monomers in the presence of a free-radical initiator a stable free radical at the first step to obtain a reaction product which contains a residual unreacted acrylic monomer; and b) reaction at the second step of one or more vinyl monomers with the reaction product from the first step to obtain a second block which contains a residual unreacted acrylic monomer. Also described are versions of said method of producing a block-copolymer. Described is a block-copolymer obtained using said methods, containing: a) a first block which contains monomer links of a functionalised acrylic monomer, having functional groups which are epoxy, acid, anhydride, amine, amide and hydroxy groups, and monomer links of a vinyl monomer; and b) a second block which contains monomer links of one or more vinyl monomers and monomer links of a functionalised acrylic monomer, having functional groups which are epoxy, acid, anhydride, amine, amide and hydroxy groups in the first block. Described is a thermoplastic polymer composition which is used to obtain materials with high impact resistance and mechanical strength, which contains: (a) 1-98 wt % of a first thermoplastic, having functional groups selected from a group consisting of amine, amide, imide, carboxyl groups, carbonyl, carbonate ester, anhydride, epoxy, sulpho, sulphonyl, thionyl, sulphydryl, cyano and hydroxy; (b) 0.01-25 wt % of said block-copolymer, which contains a functional group which is capable of reacting with the functional group in the thermoplastic; and (c) 1-98 wt % of a second thermoplastic polymer which is miscible or compatible with the second block of said block-copolymer.

EFFECT: obtaining block-copolymers which can be used as reactive compatibility agents of thermoplastic mixtures of polymers.
