AGENT FOR REDUCING HYDRODYNAMIC RESISTANCE AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2016 - IPC C08F10/14 C08F4/642 C08F4/654 C10L1/16 C10L10/00 

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.
