ABSTRACT:
The present invention relates to a semicrystalline propylene polymer composition prepared by polymerizing propylene, ethylene and/or C4-C18-1-alkenes, where at least 50 mol % of the monomer units present stem from the polymerization of propylene and at least 20% by weight of the propylene polymer composition is the result of a polymerization using metallocene catalysts,with a melting point TMof from 65 to 170° C.,where the semicrystalline propylene polymer composition can be broken down intofrom 65 to 85% by weight of a principal component A,from 10 to 35% by weight of an ancillary component B andfrom 0 to 25% by weight of an ancillary component C.
