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 of2g′LCB-1g′LCBthat is less than about 0.22, where1g′LCBis the long chain branching index for a fraction of the composition having a Mwof 100,000 and2g′LCBis the long chain branching index for a fraction of the composition having a Mwof 500,000.
