The present invention relates to a method for producing butadiene-styrene block copolymers by copolymerisation of styrene and butadiene in a hydrocarbon solvent medium in the presence of an organolithium initiator and a modifier, with subsequent treatment of "living" polymer chains using a coupling agent. The method includes stages wherein, at stage (i), polymerisation of styrene is carried out in the presence of n-butyllithium and a modifier selected from tetrahydrofuran and/or di-C1-C6-alkyl ethers of ethylene glycol, so as to produce a polystyrene block of "living" polystyryllithium; and at stage (ii), butadiene is added to the reaction mixture obtained at stage (i) and synthesis of a polybutadiene block is carried out, optionally in the presence of a modifier selected from di-C1-C6-alkyl ethers of diethylene glycol, wherein said modifier is introduced after the beginning of the butadiene polymerisation, so as to produce a "living" block copolymer of polystyrene-polybutadienyllithium. Furthermore, stage (iii) of the claimed method includes treatment of the obtained block copolymer of polystyrene-polybutadienyllithium using a coupling agent, where diphenyldichlorosilane and/or silicon tetrachloride are used as said coupling agent. The technical result of the invention is the production of butadiene-styrene block copolymers with an increased content of 1,2-vinyl units and with a narrow molecular-weight distribution, with a simultaneous reduction in both the consumption of polymerisation modifiers and the time taken to carry out the process.

The invention relates to the field of producing polymers and copolymers of olefin oligomers produced by a trimerization reaction of olefin monomers. There is disclosed a process which comprises producing olefin oligomers with the aid of a trimerization catalyst system prepared using UHF irradiation for activating individual components of the trimerization catalyst system. The use of the trimerization catalyst system thus improved and having increased activity provides for increased effectiveness in the production of olefin oligomers from ethylene or other olefin monomers, inter alia, at a low pressure of ethylene. The olefin oligomers thus produced are then polymerized or copolymerized using processes known in the art.The technical effect consists in increasing the effectiveness of the production of olefin oligomers which are then used in a polymerization or copolymerization reaction.
