High melt flow polypropylene composition

Abstract

The present invention relates to a polypropylene composition comprising a crystalline fraction (CF) and a soluble fraction (SF), both determined according to CRYSTEX QC analysis, whereby said soluble fraction (SF)—is present in the polypropylene composition in an amount in the range of 10.0 to 35.0 wt.-%, preferably in the range of 11.0 to 32.5 wt.-%, more preferably in the range of 12.0 to 30.0 wt.-%, based on the total weight of the polypropylene composition, —has an intrinsic viscosity (iV(SF)) of at least 2.0 dl/g, preferably in the range of 2.3 to 4.5 dl/g, more preferably in the range of 2.5 to 4.3 dl/g, and—has an ethylene content (C2(SF)) in the range of 14.0 to 29.0 wt.-%, preferably in the range of 17.0 to 26.0 wt.-%, more preferably in the range of 19.0 to 24.0 wt.-%, based on the total weight of the soluble fraction (SF), as determined by FT-IR spectroscopy calibrated by quantitative 13C-NMR spectroscopy; wherein the ratio of the intrinsic viscosity of the soluble fraction to the intrinsic viscosity of the crystalline fraction (iV(SF)/(iV(CF)) is in the range of 2.5 to 5.0, preferably in the range of 2.6 to 4.8; and wherein the polypropylene composition has a melt flow rate MFR2 (230° C., 2.16 kg, ISO 1133) in the range of 105 to 320 g/10 min, preferably in the range of 107 to 300 g/10 min, more preferably in the range of 110 to 280 g/10 min; a process for producing said polypropylene composition; an article comprising said polypropylene composition; and the use of said polypropylene composition for the production of an article.
