Propylene based terpolymer for containers

摘要

A container comprising a propylene, ethylene, 1-hexene terpolymer wherein in the terpolymer:
(i) the content of ethylene derived units ranges from 0.5 wt% to 2.0 wt%;
(ii) the content of 1-hexene derived units ranges from 1.5 wt% to 5.5 wt%;
(iii) the content of ethylene derived units fulfills the following equation (I); C �¢ 2 < C �¢ 6 * 0.55
wherein C2 is the content of ethylene derived units wt% and C6 is the content of 1-hexene derived units wt%;
(iv) the melt flow rate MFR measured according to ISO 1133 ,230° C, 2.16 kg ranges from 15 to 80g/10min.
