摘要

A multimodal polyethylene copolymer comprising:
(III) 35 to 55 wt% of a lower molecular weight ethylene homopolymer component having an MFR 2 of 200 to 400 g/10min;
(IV) 45 to 65 wt% of a higher molecular weight ethylene copolymer component of ethylene and at least one C3-12 alpha olefin comonomer;
wherein said multimodal polyethylene copolymer has a density of 955 to 962 kg/m 3 , an MFR 2 of 2.0 to 10 g/10min and an Mw/Mn of more than 9.0.
