摘要： The present invention relates to a polymer composition comprising at least the following components: (A) 30.0 to 80.0 wt.-% based on the overall weight of the polymer composition of a single-site catalyst produced C 2 C 3 heterophasic copolymer (HECO); whereby said copolymer has a melting point in the range of 150 to 162°C determined by differential scanning calorimetry according to ISO 11357-3; a MFR 2 (230°C, 2.16 kg) determined according to ISO 1133 in the range of 5.0 to 40.0 g/10 min; a total C2-content in the range of 1 to 10 wt.-% based on the overall weight of component (A); and a soluble fraction (SF) based on the total weigh of component (A) in the range of 10 to 50 wt.-% determined according to CRYSTEX QC, Polymer Char as described in the description; 20.0 to 70.0 wt.-% based on the overall weight of the polymer composition of a propylene homopolymer; whereby said propylene homopolymer has a MFR 2 (190°C, 2.16 kg) determined according to ISO 1133 in the range of 1.0 to 20.0 g/10 min; and a F 30 melt strength determined according to ISO 16790 of at least 10 cN; with the proviso that the weight proportions of components A) and B) add up to 100 wt.-%. Furthermore, the invention relates to a film comprising the polymer composition according to the invention and to coated articles comprising at least one layer comprising said polymer composition.

摘要： The present invention relates to a heterophasic polypropylene composition having excellent stiffness and impact properties at medium to high flowability. In particular, the present invention relates to a heterophasic polypropylene composition comprising a propylene butene copolymer and a propylene ethylene elastomer. The heterophasic polypropylene composition is prepared using a Ziegler-Natta catalyst. Furthermore, the present invention also relates to a preparation process for the heterophasic polypropylene composition, and to articles comprising the heterophasic polypropylene composition as well as to use of the heterophasic polypropylene composition for the manufacture of articles.
