| titleOfInvention | Process for preparing propylene polymers with an ultra high melt flow rate |
| abstract | Process for the production of propylene homo- or copolymers with an MFR2 (230°C, 2.16kg, ISO 1133) in the range of 800 to 3000 g/1Omin, said process comprises the steps of a) polymerising propylene and optionally an ethylene and/or C 4 -C 12 alpha-olefin comonomer in a slurry reactor in the presence of a polymerisation catalyst system, obtaining as slurry reactor product a first propylene homo- or copolymer component with an MFR2 (230°C, 2.16kg, ISO 1133) in the range of 1000 to 4000 g/1Omin, b) transferring the slurry reactor product into a gas phase reactor c) further polymerising propylene and optionally an ethylene and/or C4-Ci2 alpha-olefin comonomer in the presence of said slurry reactor product and the polymerisation catalyst system d) optionally recovering the so produced propylene homo- or copolymer for further processing, said polymerisation catalyst system comprises (i) a Ziegler-Natta procatalyst (ii) an organometallic cocatalyst and (iii) an external donor represented by formula (I) Si(OCH 2 CH 3 ) 3 (NR 1 R 2 ) (I) wherein R1 and R2 can be the same or different and represent a hydrocarbon group having 1 to 12 carbon atoms; and the use of such prepared polymers for blow moulding applications. |
