    Abstract: Molding compositions made from a high-molecular-weight propylene polymer with a melt massflow rate MFR of from 0.3 to 1 g/10 min, to ISO 1133 at 230°C and 5 kg, and with a proportion of ß modification crystallites in the range from 2 to 20% by weight. The molding compositions of the invention preferably comprise a quinacridone pigment as nucleating agent. The high-molecular-weight propylene polymer used preferably comprises a high-molecular-weight propylene copolymer with up to 30% by weight of other copolymerized olefins having up to 10 carbon atoms. One of the uses of the molding compositions of the invention is as materials for pipes.
