FIELD: organic chemistry, polymers, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of polymers by method of "living" radical polymerization and to "living" polymers synthesized by this method. Invention describes a mixture of initiating agent of "living" radical polymerization represented by the formula (1): , and compound represented by the formula (2): (R¹Te)₂ used for polymerization of vinyl monomers taken in the ratio from 0.1 to 100 moles of compound of the formula (2) per one mole of initiating agent of the formula (1) wherein R¹ means (C₁-C₈)-alkyl, aryl or aromatic heterocyclic group; each among R² and R³ means hydrogen atom or (C₁-C₈)-alkyl group; R⁴ means aryl, substituted aryl, hydroxycarbonyl group or cyano-group wherein R has value given above. Also, invention describes a method for synthesis of "living" polymer by method of "living" radical polymerization wherein vinyl monomer is polymerized by using a mixture of initiating agent of "living" radical polymerization represented by the formula (1) and compound represented by the formula (2). Invention describes polymer synthesized by polymerization of vinyl monomer by using initiating agent mixture given above. Also, invention describes methods of synthesis of diblock-copolymer and triblock-copolymer and these diblock-copolymers and triblock-copolymers are described. Invention provides a method for synthesis of polymers comprising "living" chain allowing carrying out the precise control of molecular masses and molecular-mass pattern. Polymers synthesized by the proposed method allow easy conversion of their terminal groups to other functional groups useful for preparing macromonomers that can be used as places for pouring off and useful as agents providing compatibility and as materials for producing block-polymers.

EFFECT: improved method of synthesis, valuable properties of polymers.
