Beschreibung
Zusammenfassung:	Polypropylene (PP) with a reduced tendency to turn white under load deformation (white break), comprises the following:(A) 70 - 95 wt.% high-grade isotactic PP with an isotactic index greater than 90 and a MFI of 0.1 - 100 g/ 10 minutes, comprising a propylene homopolymer, or a copolymer with one or more alpha-olefin comprising at least 50 mol.% propylene; and (B) 5 - 30 wt.% high-grade amorphous PP containing up to 10 wt.% crystalline PP, having a maximum melt enthalpy of 40 J / g and MFI of 0.1-100 g / 10 minutes, comprising a propylene homopolymer, or a copolymer with one or more alpha-olefin comprising at least 80 mol.% propylene.
