| titleOfInvention | Propylene Polymer Composition |
| abstract | A propylene polymer composition having a high impact strength and a high stiffness for the manufacture of parts having an excellent surface quality comprisingn A) 70 to 98 wt.-% of a heterophasic propylene copolymer with ethylene or an alpha-olefin with 4 to 12 carbon atoms, the propylene copolymer, which contains more than 60 wt.-% propylene, having a melt flow rate (MFR 2 ) of 0.5 to 50 g/10 min and a ratio between elastomer molecular weight and total molecular weight expressed as M w /M w (XCS) of more than 0.8,n M w being the weight average molecular weight of the propylene copolymer and M w (XCS) being the weight average molecular weight of the propylene copolymer which is soluble in xylene at +23° C., and the propylene copolymer further containing a portion of 5 to 35 wt.-% soluble in xylene at +23° C. (XCS content), n B) 2 to 30 wt.-% of a mineral filler, C) 0.0001 to 1.0 wt.-% of a β-nucleating agent promoting the β-modification of the propylene copolymer,n nsaid composition having a content of β-modification of more than 50% determined by differential scanning calorimetry (DSC) and an impact strength at −20° C. which is at least 50% higher than the impact strength of the propylene copolymer (A). |
