FIELD: chemistry.SUBSTANCE: invention relates to chemistry of polymers in additives used in transportation of oil and oil products. Described is a method of producing an agent for reducing hydrodynamic resistance of a hydrocarbon stream, which is a stabilised powdered high-molecular poly-alpha-olefin. Method involves polymerisation of higher alpha-olefins in medium of fluorinated organic compounds using a titanium-magnesium catalyst, modified with an electron-donor compound, followed by extraction of powdered poly-alpha-olefin and stabilisation of latter by adding an adhesion reducing powder. Electron-donor compound is glycol ethers, phthalic acid esters. Synthesis is carried out at a given ratio of components of system. Agent for reducing hydrodynamic resistance is characterised by component weight ratio, %: poly-alpha-olefin 80-90 %, adhesion reducing powder 10-20 %.EFFECT: obtaining an agent for reducing hydrodynamic resistance in form of a stable powder composition, and which does not require additional conditions for storage and transportation of product.3 cl, 1 tbl, 22 ex |
