METHOD OF PRODUCING ACTIVE BASE FOR ANTI-TURBULENCE ADDITIVE BASED ON HOMO- AND COPOLYMERISATION OF α-OLEFINS Russian patent published in 2013 - IPC C08F10/14 C08F2/14 C08F4/16 C10L1/10 

FIELD: chemistry.

SUBSTANCE: described is a method of producing polymer bases for anti-turbulence additives. The method involves polymerisation of C₆-C₃₀ α-olefins in the presence of a product of reducing titanium tetrachloride with an organoaluminium compound as a catalyst, and a complex based on 3-thia-1,5-diazabicyclo[3.2.1]octane and dimethylaluminium chloride as a cocatalyst. Reactants are in the following molar ratios: α-olefin 1, catalyst 0.002-0.004, cocatalyst 0.02-0.04. The polymerisation reaction is carried out at temperature ranging from -20° to +20°C for 8-12 hours.

EFFECT: high output of the end product and molecular weight thereof, low molecular weight distribution.
