Abstract
A polymer composition that has a backbone chain; and a plurality of long chain branches connected to the backbone is described. The polymer composition also has a value of 2g′LCB-1g′LCB that is less than about 0.22, where 1g′LCB is the long chain branching index for a fraction of the composition having a Mw of 100,000 and 2g′LCB is the long chain branching index for a fraction of the composition having a Mw of 500,000.
