| titleOfInvention | PROCESS OF PREPARATION OF A COMPONENT OF OLYMPIC POLYMERIZATION CATALYSTS |
| abstract | Solid catalyst component for use in the polymerization of olefins and having improved activity and selectivity are prepared by: 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 DEG to 140 DEG C and thereafter the treated product is washed in step c). l |
