METHOD FOR PRODUCING ANTITURBULENT ADDITIVE FOR HYDROCARBON ROCKET PROPELLANTS Russian patent published in 2017 - IPC C08F10/14 C08F4/642 C10L1/10 C10L1/14 

FIELD: chemistry.

SUBSTANCE: invention relates to methods for producing antiturbulent additives based on (co)polymers of higher alpha-olefins and can be used in main propellant lines of liquid rocket engines (LRE). The method is carried out by means of (co)polymerizing higher α olefins in the presence of microspheroidal titanium trichloride and an organoaluminum cocatalyst. The additive is represented by methylcyclohexyldimethoxysilane in the equimolar amount to TiCl_3. The resulting higher alpha-olefin (co)polymer is subjected to cleaning from the catalyst system by means of reprecipitation from the solution to a residual content of elements Ti, Al, Si and Cl of not more than 0.001 wt %. Liquid propellant is added to the cleaned (co)polymer until the viscosity of the antiturbulent additive is 27-35 cSt.

EFFECT: obtaining a highly effiective antiturbulent additive suitable for use in LRE main propellant lines, and reducing the final content of said polymer in a liquid propellant.
