Preparation of olefin polymerization catalyst component |
| abstract |
Solid catalyst component for use in the polymerization of olefins and having improved activity and selectivity are prepared by:n a) halogenating a magnesium compound containing at least one aryloxy, alkyl carbonate or alkyloxy group with a first halide of tetravalent titanium and a first electron donor; b₁) contacting the resulting halogenated product with a second halide of tetravalent titanium; and c) washing a resulting treated halogenated product with an inert hydrocarbon liquid, wherein a second electron donor is used in step a) or step b₁) and in that the product of step b₁) is contacted in step b₂ with a third halide of tetravalent titanium at a temperature of 40° to 140°C and thereafter the treated product is washed in step c). |
