Abstract:
1. A polymer composition, comprising (i) a polypropylene homopolymer having a melt flow rate MFR (ii) a polypropylene random copolymer, prepared by copolymerization of propylene with an olefin comonomer and having an amount of olefin comonomer units of 0.2 to 5.0 wt %, and (iii) an elastomeric copolymer of propylene and at least one olefin comonomer, comprising from 10 to 50 wt % olefin comonomer units based on the weight of the elastomeric copolymer, wherein the polymer composition has a tensile modulus, determined according to ISO 527-2/1 B at 1 mm/min. and 23° C., of at least 1400 MPa; wherein the polymer composition has a melting point of from 155.6° C. to less than 164° C.; and wherein the polypropylene homopolymer and the polypropylene random copolymer are blended during polymerization to result in a polypropylene-based matrix.
