    摘要： The invention relates to novel propylene polymers with improved properties especially with improved stiffness and impact strength comprising propylene homopolymers or propylene block copolymers with 90.0 to 99.9 wt% propylene and 0.1 to 10 wt% α-olefins with 2 or 4 to 18 carbon atoms, or mixtures thereof, wherein the propylene homopolymers or propylene block copolymers are β-nucleated propylene polymers, whereby the β-nucleated propylene homopolymers have an IRτ ≥0.98, a tensile modulus ≥1500 MPa at +23° C and a Charpy impact strength, ≥3 kJ/m2 at -20° C using notched test specimens, and the β-nucleated propylene block copolymers are polymers having an IRτ of the propylene homopolymer block of ≥0.98, a tensile modulus ≥1100 MPa at +23° C and a Charpy impact strength of ≥6 kJ/m2, at -20° C using notched test specimens. The propylene polymers with an improved property spectrum are suitable for producing molded parts in a pipe system, such as pipes and fittings, inspection chambers, pipe ducting systems, extrusion or compression molded sheets and the like.

    摘要： Single- or multilayer propylene polymer pipes and pipe components for pipelines with improved resistance to rapid crack propagation made from a propylene homopolymer with a melt index of 0.05 to 10 g/10 min at 230 °C/2.16 kg or propylene block copolymer from 90.0 to 99.9 wt% of propylene and 0.1 to 10.0 wt% of α-olefins with 2 or 4 to 18 carbon atoms with a melt index of 0.05 to 8 g/10 min at 230 °C/2.16 kg or mixtures thereof, wherein the propylene homopolymers or propylene block copolymers are β-nucleated propylene polymers, and the propylene polymer pipes for pipelines made from the β-nucleated propylene homopolymers have a rapid crack propagation characterized by a critical temperature of -5 to + 40 °C and a critical pressure ≥3 bar below the critical temperature and the propylene polymer pipes made from β-nucleated propylene block copolymers have a rapid crack propagation characterized by a critical temperature of -25 to 0 °C and a critical pressure ≥3 bar below the critical temperature. The propylene polymer pipes with improved resistance to rapid crack propagation are suitable for the transportation of fluids and pressurized fluids such as natural gas, water and the like.
