Abstract:
A polyethylene composition having a polydispersity index of less than or equal to 3, an average branching index (g') as measured by gel permeation chromotography/viscosity (GPC/Vis).gtoreq.0.9, and a melt strength (MS) (centiNewton, 190.degree. C.) that satisfies the relationship: ##EQU3## wherein said composition comprises a branched polyethylene copolymer prepared by insertion polymerization of ethylene, ethylene-containing macromers, and optionally, additional copolymerizable monomers, and an essentially linear ethylene copolymer having density of 0.900-0.935 g/cm.sup.3, polydispersity index of 1.8-3.5 and a melt index (2.16 kg/190.degree. C.) of 0.3-7.5.
