Abstract: A polypropylene composition made from or containing: A) from 50 wt % to 90 wt %, based upon the total weight of the polypropylene composition, of a propylene homopolymer; and B) from 10 wt % to 50 wt %, based upon the total weight of the polypropylene composition, of a copolymer of propylene and ethylene having from 30.0 wt % to 70.0 wt %, based upon the total weight of the copolymer, of ethylene derived units; the polypropylene composition having: i) an intrinsic viscosity of the fraction soluble in xylene at 25° C. between 2.2 and 4.0 dl/g; ii) a MFR L from 0.5 to 100 g/10 min; and iii) a xylene soluble fraction ranging from 10 wt % to 50 wt %, based upon the total weight of the polypropylene composition.
