Abstract
A polyethylene homopolymer comprising the following properties: a) a melt index (I2) from 1.0 to 3.5 dg/min; b) a Mw(abs) versus I2 relationship: Mw(abs)≥A+B(I2), where A=3.20×105 g/mole, and B=−8.00×103 (g/mole)/(dg/min); c) a Mw(abs) versus I2 relationship: Mw(abs)≤C+D(I2), where C=3.90×105 g/mole, and D=−8.00×103 (g/mole)/(dg/min).
