Beschreibung
Zusammenfassung:	of the disclosure Polypropylene molding compound for producing calendered films A polypropylene molding compound which comprises 99.5 to 99.9% by weight of a homopolymer or copolymer of propylene with a MFI 230/2.16 of 2.0 to 25 g/10 min and 0.01 to 0.5% by weight of a fluorine-containing thermoplastic polymer with a fluorine content of at least 50% and a melting point of below 250.degree.C makes it possible to produce, by calendering, polypropylene films of high quality. The addition of fluoropolymers is not only effective as regards the release effect, but also results in significantly fewer deposits and brings about an improved take-off behavior in comparison to the use of conventional lubricants.
