摘要：
The present invention relates to a polymer composition, comprising
(i) a polypropylene homopolymer,
(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 wt%, and
(iii) an elastomeric copolymer of propylene and at least one olefin comonomer,
the polymer composition having a tensile modulus, determined according to ISO 527-2/1 B at 1 mm/min. and 23°C, of at least 1200 MPa.
