Claim 19:
20. A polypropylene composition comprising a terpolymer containing propylene, ethylene and 1-hexane, wherein the polypropylene composition
(i) has a content of ethylene derived units of at least 1.5 wt %;
(ii) has a content of 1-hexane derived units of at least 1.5 wt %;
(iii) has a melt flow rate of 0.10 to 0.70 g/10 min determined by ISO 1133-1:2011 at 230° C. and 2.16 kg; and
(iv) has a ratio of weight average molecular weight (Mw) to number average molecular weight (Mn) of the terpolymer of 7.0 to 20.0, wherein Mw and Mn are measured according to ASTM D6474-12, wherein a lowest temperature at which maximum 1 out of 10 pipes made from the polypropylene composition fails determined by DIN8078 is 0.0° C.
