Slurry polymerization process for the preparation of a polypropylene (PP) having a decaline soluble fraction (DS) of equal or below 2.5 wt.-%,
wherein
(a) a Ziegler-Natta catalyst (ZN),
(b) propylene and optionally ethylene and/or an C 4 to C 12 ±-olefin, and
(c) a diluent (D) comprising a donor agent (DA),
are fed into a first reactor vessel (R1) and the polymerization of said polypropylene (PP) takes place in at least said first reactor (R1). |
