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 .sup.2g'.sub.LCB-.sup.1g'.sub.LCB that is less than about 0.22, where .sup.1g'.sub.LCB is the long chain branching index for a fraction of the composition having a M.sub.w of 100,000 and .sup.2g'.sub.LCB is the long chain branching index for a fraction of the composition having a M.sub.w of 500,000.
