Beschreibung
Zusammenfassung:	The invention relates to a polypropylene composition comprising a terpolymer containing propylene, ethylene and 1-hexene wherein the polypropylene composition (i) has a content of ethylene derived units of at least 1.5 wt%; (ii) has a content of 1-hexene 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 (230 DEG C, 2.16 kg); and (iv) has a ratio of weight average molecular weight (Mw) to numeric average molecular (Mn) weight of the terpolymer of 7.0 to 20.0, wherein Mw and Mn are measured according to ASTM D6474-12. 本发明涉及包含三元共聚物的聚丙烯组合物，所述三元共聚物包含丙烯、乙烯和1-己烯，其中所述聚丙烯组合物(i)具有至少1.5重量％的乙烯衍生单元含量；(ii)具有至少1.5重量％的1-己烯衍生单元含量；(iii)具有由ISO1133-1:2011(230℃，2.16kg)测定的0.10至0.70g/10min的熔体流动速率；和(iv)具有7.0至20.0的所述三元共聚物的重均分子量(Mw)与数均分子量(Mn)之比，其中Mw和Mn根据ASTM D6474-12来测量。
