METHOD OF PRODUCING ANTI-TURBULENT ADDITIVE WITH MONOMER RECYCLING, METHOD OF PRODUCING ANTI-TURBULENT ADDITIVE, METHOD OF PRODUCING HIGHER POLY-α-OLEFINS FOR SAID METHODS AND ANTI-TURBULENT ADDITIVE BASED THEREON Russian patent published in 2014 - IPC C08F10/00 C08F10/14 C08F2/02 C08F4/642 C10L1/10 

FIELD: chemistry.

SUBSTANCE: described is a method of producing an anti-turbulent additive with monomer recycling, a method of producing an anti-turbulent additive, a method of producing higher poly-α-olefins for said methods and an anti-turbulent additive based thereon. The methods employ a substance with a boiling point higher than that of the starting monomer by not less than 73°C as a precipitation agent for the obtained polymer.

EFFECT: reduced monomer loss, low cost of the methods by preventing formation of azeotropic mixtures of the precipitation agent and the monomers while maintaining high degree of purity of the recycled monomers.
