METHOD OF POLYMERIZATION IN PRESENCE OF ANTISTATIC ACTION Russian patent published in 2017 - IPC C08F2/34 C08F2/44 C08F10/00 C08F10/02 

FIELD: chemistry.

SUBSTANCE: invention relates to the method of producing polyolefins by polymerization of olefins at a temperature of 20-200°C and a pressure of 0.1-20 MPa, in the presence of a polymerization catalyst and an antistatic composition in a polymerization reactor. The antistatic composition is a mixture containing an oil-soluble surfactant, water and one or more aliphatic hydrocarbons. A mixture of an oil-soluble surfactant, water and one or more aliphatic hydrocarbons is produced. The mixture contains, wt %: 10.0 to 69.9 of an oil-soluble surfactant, 0.1 to 2.0% of water, 30.0 to 89.9% of aliphatic hydrocarbon. The mixture is then fed to the polymerization reactor as such or in a diluted form. Also, the use of an antistatic agent composition as an antistatic agent is described.

EFFECT: simplification of the production method, improvement of the product properties, improvement of activity, ensuring good processability of the method with respect to the formation of fine particles.
