Claim 2:
3. The heterophasic polypropylene composition (C) according to claim 1, having one or more of the following properties:
i) an intrinsic viscosity of the soluble fraction (IV(SF)) in the range from 2.00 to 3.50 dl/g;
ii) an ethylene content of the soluble fraction (C2(SF)), measured by Infrared Spectroscopy during CRYSTEX analysis, in the range from 25.0 to 50.0 wt. %;
iii) an intrinsic viscosity of the crystalline fraction (IV(CF)) in the range from 1.00 to 2.00 dl/g;
iv) an ethylene content of the crystalline fraction (C2(CF)), measured by Infrared Spectroscopy during CRYSTEX analysis, in the range from 5.0 to 20.0 wt. %;
v) a ratio between the intrinsic viscosity of the soluble fraction and the intrinsic viscosity of the crystalline fraction (IV(SF)/IV(CF)) in the range from 1.40 to 3.00; and
vi) a total ethylene content (C2), measured by Infrared Spectroscopy during CRYSTEX analysis, in the range from 10.0 to 20.0 wt. %.
