    Abstract: The present invention is directed to a polypropylene composition (C), an article comprising the polypropylene composition (C) and the use of the polypropylene composition (C) to reduce paintability failure of a molded article. The polypropylene composition (C) comprises (a) 40.0 to 80.0 wt. %, based on the total weight of the composition, of a propylene copolymer (R-PP) having: (a1) a comonomer content in the range of 1.5 to 8.0 wt. %, and (a2) a melt flow rate MFR2 (230 ° C.) measured according to ISO 1133 in the range of 5.0 to 100.0 g/10 min, and (b) 20.0 to 40.0 wt. %, based on the total weight of the composition, of a mineral filler (F) being selected from the group consisting of talcum, wollastonite, kaolin, and mica, wherein the polypropylene composition (C) has a melt flow rate MFR2 (230 ° C.) measured according to ISO 1133 in the range of 5.0 to 45.0 g/10 min.

    Abstract: A process for the preparation of a polypropylene in a sequential polymerization process including a pre-polymerization reactor and at least two polymerization reactors connected in series. The polymerization in the at least two polymerization reactors takes place in the presence of a Ziegler-Natta catalyst. The Ziegler-Natta catalyst includes (a) a pro-catalyst that has a compound of a transition metal, a compound of a metal which metal is selected from one of the groups 1 to 3 of the periodic table (IUPAC), and an internal electron donor, (b) a co-catalyst, and (c) an external donor. The Ziegler-Natta catalyst is present in the pre-polymerization reactor. Ethylene and propylene are fed to the pre-polymerization reactor in a feed rate ratio of 0.5 to 10.0 g/kg.
