Abstract
A catalyst component comprising Ti, Mg, Cl, and an electron donor compound having porosity of at least 0.2 cm3/g and characterized by the fact that it further comprises Cu oxide, with the proviso that when the electron donor compound is selected from esters of phthalic acids, the porosity is of at least 0.45 cm3/g.
Claims10
A solid catalyst component comprising:
- (i) an amount (Ti) of titanium, based upon the total weight of the solid catalyst component,
- (ii) an amount (Mg) of magnesium, based upon the total weight of the solid catalyst component,
- (iii) an amount (Cl) of chloride, based upon the total weight of the solid catalyst component,
- (iv) an amount (IED) of an internal electron donor compound, based upon the total weight of the solid catalyst component, and
- (v) an amount (Cu) of copper oxide, based upon the total weight of the solid catalyst component,
- wherein
- the solid catalyst component has a porosity of at least 0.2 cm3/g as determined by a mercury method and pores with a maximum radius of about 1 upm,
- providing that
- when the internal electron donor compound is selected from the group consisting of esters of phthalic acids, the porosity of at least 0.45 cm3/g.
