Abstract
Disclosed is a process for obtaining a solid catalyst component for ethylene polymerization and copolymerization, wherein a carrier of particulate silica (65 to 85% by weight) is impregnated with a catalytically active portion (15 to 35% by weight) including titanium, magnesium, chlorine, alkoxy groups and at least one organometallic compound of the groups 1, 2, 12 or 13 of the periodic table. Further, the invention refers to the solid catalyst component thus obtained and to a process for ethylene polymerization and copolymerization wherein is used said catalyst. The catalyst obtained is suitable for the production of ethylene homo- and copolymers as narrow molecular weight distribution high density polyethylene (NMWHDPE) and linear low density polyethylene (LLDPE) with controlled morphology and improved structure.
