Beschreibung
Zusammenfassung:	A propylene/1-hexene copolymer in which: i) the content of 1-hexene derived units is from 1.5 wt% to 2.5 wt% and the content of propylene derived units is from 97.5 wt% to 98.5 wt% as determined by C13-NMR; ii) a melting temperature, as determined by DSC, of 148 DEG C to 153 DEG C; iii) the amount of fraction insoluble in xylene at 25 DEG C is higher than 97.0%; iv) a melt flow rate (MFR), as determined according to ISO 1133, 230 DEG C, 2.16 kg, of from 35 g/10 min to 65 g/10 min. The copolymers are useful in the production of injection molded articles, in particular double-walled injection molded articles. 一种丙烯/1-己烯共聚物，其中：i)通过C13-NMR测定的1-己烯衍生单元的含量为1.5重量％至2.5重量％，并且丙烯衍生单元的含量为97.5重量％至98.5重量％；ii)通过DSC测定的熔化温度为148℃至153℃；iii)在25℃不溶于二甲苯的部分的量高于97.0％；iv)根据ISO1133、230℃、2.16kg测定的熔体流动速率(MFR)为35g/10min至65g/10min。所述共聚物可用于生产注塑制品，特别是双壁注塑制品。
