Abstract
Provided are bimodal linear low density polyethylene copolymers (B-LLDPE copolymers) that have a combination of improved properties comprising at least one processability characteristic similar or better than that of an unblended monomodal ZN-LLDPE and a dart impact property similar or better than that of an unblended monomodal MCN-LLDPE. For the various aspects, the B-LLDPE copolymer has a density from 0.8900 to 0.9300 g/cm; a melt index (I) from 0.1 g/10 min. to 5 g/10 min.; a Mfrom 600,000 to 1,900,000 g/mol; and a SHI from 5.35 to 75 η*(1.0)/η*(100). The B-LLDPE copolymer can be further characterized by a first melt flow ratio (I/I) from 32 to 140 and a first molecular weight ratio (M/M) from 4.5 to 11.
