Abstract: The present invention relates to a solid, particulate catalyst component having an mean particle size range of 5 to 200 μm and comprising a compound of a Group 2 metal, a compound of a transition metal of Group 4 to 6, and at least two internal electron donors being different to each other and being non-phthalic organic compounds selected from (did)esters of non-phthalic carboxylic (did)acids, 1,3-diet hers and did-esters of 1,3-diol compounds and derivatives thereof, and wherein the solid particulate catalyst component is free of any external support material. The invention relates also to the preparation of the catalyst component and a polymerization process for producing propylene polymers.

Abstract: Propylene is polymerised in the presence of a polymerisation catalyst comprising a solid catalyst component, an organoaluminium compound and an external electron donor, the process comprising the steps of (i) contacting propylene and hydrogen with the polymerisation catalyst in polymerisation conditions in a polymerisation reactor to produce a polymer of propylene; (ii) recovering the polymer of propylene from the polymerisation reactor; wherein the polymer of propylene has MFR of from more than 100 to 10000 g/10 min. The solid catalyst component comprises titanium, magnesium, halogen and an internal electron donor, characterised in that the internal electron donor is a compound according to formula (I) with R1 and R2 being the same or different and being a linear or branched C1-C12-alkyl group, and with R being H or a linear, branched or cyclic C1 to C12-alkyl, whereby it is preferred that R is not H. The external electron donor is a silane compound having the formula Si(OR11)nR104-n, wherein each R10 is independently a linear or branched C1-C4 alkyl, preferably methyl or ethyl; and each R10 is independently a linear or branched alkyl group having from 1 to 24 and optionally containing an atom of group 15 of periodic table of elements or comprises a cyclic group having from 6 to 12 carbon atoms.

Abstract: The present invention is directed to a process for producing a solid olefin polymerization catalyst component from an emulsion wherein the particle size of the solid catalyst or the droplet size of the emulsion is controlled. The actual size of the droplets or the solid catalyst particles is measured, or alternatively, both are measured. Then a difference between the actual size and the set point is calculated and the process is controlled based on the difference.
