Claim Text:
1. A polyethylene blend comprising one or more ethylene polymers and one or more dendritic polybutadiene modifiers, wherein the modifier has: 1) a g′ vis value less than 0.75; 2) a Cayley tree topology with a layer number of 2 or more, 3) an average Mw of 1500 g/mole or more between branch points, and 4) a Mw from 50,000 to 2,000,000 g/mol; wherein the complex viscosity at 0.1 sec −1 of the modifier is equal to or greater than the complex viscosity at 0.1 sec −1 of the polyethylene prior to combination with the modifier.
