ETHYLENE POLYMERIZATION CATALYST Russian patent published in 1997 - IPC

Abstract SU 955591 A1

FIELD: catalysts for olefin polymerization processes. SUBSTANCE: ethylene polymerization catalyst containing titanium compound on magnesium-containing carrier described by gross formula MgmClnCpHg, where m = 0.80-0.95, n = 1.60-1.90, p = 0.60- 1.60, and g = 1.40-3.40 is distinguished by having, as titanium compound, compound with general formula (C6H5O)aTiCl4-a where a = 0.25-1.8, whereas titanium compound content in catalyst constitutes 5.8 to 18.6%. EFFECT: increased catalyst activity.
