METHOD OF OBTAINING ETHYLENE POLYMERS Russian patent published in 2017 - IPC C08F10/02 C08F2/00 C08F2/34 C08F4/64 

FIELD: chemistry.

SUBSTANCE: process of producing ethylene polymers involves the polymerization of ethylene, additionally with one or more comonomers α-olefins CH₂= CHR in the presence of (i) a solid catalyst component comprising titanium, magnesium, halogen and further an internal electron-donor compound, (ii) an aluminium alkyl compound, and (iii) an antistatic compound derived from hydroxyesters having at least two free hydroxyl groups, obtained from carboxylic acids with 8-22 carbon atoms and from polyalcohols. The weight ratio Al-alkyl compound to the solid component of catalyst is more than 0.80 and less than 15 units. The weight ratio of antistatic compound to the alkylaluminium compound is more than 0.10 units.

EFFECT: reduction in the formation of polymer buildup on the equipment polymer installation while achieving good operating path, improving polymer morphology.
