Abstract:
A polypropylene composition made from or containing: A) from 50 wt % to 90 wt %; of a propylene homopolymer; B) from 10 wt % to 50 wt %; of a copolymer of propylene having from 30.0 wt % to 70.0 wt %, of ethylene derived units, based upon the total weight of the copolymer; the sum of the amount of component A) and B) being 100; the polypropylene composition having: i) an intrinsic viscosity of the fraction soluble in xylene at 25° C. between 2.2 to 4.0 dl/g; ii) a MFR L (Melt Flow Rate according to ISO 1133, condition L, at 230° C. and 2.16 kg load) from 0.5 to 100 g/10 min; iii) a xylene soluble fraction ranging from 20 wt % to 50 wt %, based upon the total weight of the polypropylene composition; wherein the polypropylene composition being obtained by a polymerization process wherein the catalyst system contains bismuth.

Claim (Index 1):
A polypropylene composition comprising:\n A) from about 50 wt % to about 90 wt %; of a propylene homopolymer having a fraction insoluble in xylene at 25\u00b0 C., higher than about 90%; and a MFR L (Melt Flow Rate according to ISO 1133, condition L, at 230\u00b0 C. and 2.16 kg load) from about 0.5 to about 200 g/10 min; B) from about 10 wt % to about 50 wt %; of a copolymer of propylene and ethylene having from about 30.0 wt % to about 70.0 wt %, of ethylene derived units, based upon the total weight of the copolymer; the sum of the amount of component A) and B) being 100; the polypropylene composition having: i) an intrinsic viscosity of the fraction soluble in xylene at 25\u00b0 C. between about 2.2 to about 4.0 dl/g; ii) a MFR L (Melt Flow Rate according to ISO 1133, condition L, at 230\u00b0 C. and 2.16 kg load) from about 0.5 to about 100 g/10 min; iii) a xylene soluble fraction ranging from about 20 wt % to about 50 wt %, based upon the total weight of the polypropylene composition; wherein the polypropylene composition being obtained by a two steps polymerization process comprising the steps of: step a) polymerizing propylene to obtain component A) in the presence of a catalyst comprising the product of a reaction between: a) a solid catalyst component comprising Ti, Mg, Cl, and an internal electron donor compound containing from about 0.1 to about 50% wt of Bi with respect to the total weight of the solid catalyst component; b) an alkylaluminum compound and, c) an electron-donor compound (external donor); and step b) polymerizing propylene and ethylene to obtain component B) in the presence of the polymerization product of step a).
