    摘要： The present invention relates to an olefin polymerization process, wherein propylene and a C4 to C10 a-olefin, preferably 1-butene and optionally ethylene are reacted in the presence of a Ziegler-Natta catalyst so as to obtain a polypropylene, wherein the polypropylene comprises C4 to C10 a-olefin, preferably 1-butene-derived comonomer units in an amount of from 0.5 wt % to 15 wt % and ethylene-derived comonomer units in an amount of 0 wt % to 3 wt %, and wherein the Ziegler-Natta catalyst comprises i) an external donor of the formula (I): (R3)z(R2O)ySi(R1)x and ii) a solid Ziegler-Natta catalyst component being free of external carrier material.

    摘要： The invention relates to a polypropylene composition (C) comprising: (i) 62 to 85 wt.-%, based on the total weight of the polypropylene composition (C), of a heterophasic propylene copolymer (HECO1) with a melt flow rate MFR2 (230° C.) measured according to ISO 1133 in the range of 6.0 to 50.0 g/10 min; (ii) 10 to 30 wt.-%, based on the total weight of the polypropylene composition (C), of a heterophasic propylene copolymer (HECO2) with a melt flow rate MFR2 (230° C.) measured according to ISO 1133 in the range of 0.1 to 5.5 g/10 min; (iii) 5 to 30 wt.-%, based on the total weight of the polypropylene composition (C), of an inorganic filler (F); wherein (a) the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO1) has a lower amount [in mol %] of C2 and/or C4 to C12 α-olefin derived comonomer units than the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO2); (b) the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO1) has a lower the intrinsic viscosity (IV) than the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO2); and (c) the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO2) has an intrinsic viscosity (IV) in the range of 6.0 to 15.0 dl/g.
