Abstract:
The present invention relates to a high flow polypropylene composition comprising (A) a low molecular weight propylene homopolymer fraction and (B) a high molecular weight propylene copolymer fraction, having a comonomer content of not higher than 8 wt %, wherein the ratio between the MFR2 of fraction (A) and the MFR2 of fraction (B) is at least 3 and wherein the MFR2 of the entire composition is at least 5 g/10 min, the values of MFR2 being measured according to ISO 1133 (230° C., 2.16 kg load), and to processes for producing such compositions and to articles made there from.
