Abstract:
The present invention concerns heterophasic propylene copolymers, comprising a propylene homopolymer (PPH) and an ethylene-propylene rubber (EPR), having a broad molecular weight distribution and a well-defined total ethylene content and a specific ratio of the intrinsic viscosities of the ethylene-propylene rubber (EPR) and the propylene homopolymer (PPH), ηEPR/ηPPH. The invention further concerns the process to produce such heterophasic propylene copolymers. The heterophasic propylene copolymers of the present invention are particularly suited for corrugated sheet and cast film applications.
