Abstract
A bimodal polyethylene copolymer comprising a lower molecular weight (LMW) component and a higher molecular weight (HMW) component, the copolymer having a z-average molecular weight (M) of from about 1,000 kg/mol to about 2,500 kg/mol, a weight fraction of the LMW component (LMW fr.) of from about 0.60 to 0.85, a ratio of a weight average molecular weight (M) of the HMW component (HMW M) to a Mof the LMW component (LMW M) of from about 14 to about 25, a zero shear viscosity (η) of from about 5×10Pa-s to about 1×10Pa-s and a HMW Mof from about 800 kg/mol to about 1,500 kg/mol.
