| titleOfInvention | Highly stereoregular polypropylene with improved properties |
| abstract | Catalyst component having average particle size equal to or lower than 40 μm comprising a magnesium halide, a titanium compound having at least a Ti-halogen bond and at least two electron donor compounds one of which being present in an amount from 15 to 50% by mol with respect to the total amount of donors and selected from succinates of formula (I) below (I) in which the radicals R1 and R2, equal to, or different from, each other are a C1-C20 linear or branched alkyl, alkenyl, cycloalkyl, aryl, arylalkyl or alkylaryl group, optionally containing heteroatoms; and the radicals R3 and R4 equal to, or different from, each other, are C1-C20 alkyl, C3-C20 cycloalkyl, C5-C20 aryl, arylalkyl or alkylaryl group with the proviso that at least one of them is a branched alkyl; said compounds being, with respect to the two asymmetric carbon atoms identified in the structure of formula (I), stereoisomers of the type (S, R) or (R, S) and at least another electron donor compound which is extractable, under the test of extractability disclosed in the characterization section, for more than 30% by mol. |
