PREPARATION OF ETHYLENE POLYMERIZATION CATALYST Russian patent published in 1997 - IPC

Abstract SU 1053352 A1

FIELD: catalysts for olefin polymerization processes. SUBSTANCE: in a method where ethylene polymerization catalyst is prepared via interaction of metal magnesium with butyl chloride in hydrocarbon solvent medium in presence of iodine at 70-90 C followed by allowing magnesium- containing carrier thus obtained to stand and treating it with titanium tetrachloride at 15-25 C and agitation, distinguishing feature is that magnesium-butyl chloride interaction is performed in presence of titanium tetrachloride at its molar ratio to magnesium from 0.0025 to 0.006. EFFECT: simplified method and increased catalyst activity.
