The invention provides an ethylene-based polymer comprising the following properties:
a) a melt index (I2)≧2.0 dg/min;b) a Mw(abs) versus I2 relationship: Mw(abs)<A+B(I2), where A=2.40×105 g/mole, and B=−8.00×103 (g/mole)/(dg/min); andc) a G′ versus I2 relationship: G′≧C+D(I2), where C=127.5 Pa, and D=−1.25 Pa/(dg/min).;The invention also provides an ethylene-based polymer comprising the following properties:
a) a melt index (I2)≧2.0 dg/min;b) a G′ versus I2 relationship: G′≧C+D(I2), where C=127.5 Pa, and D=−1.25 Pa/(dg/min)c) a chloroform extractable (Clext) versus G′ relationship: Clext.≦E+FG′, where E=0.20 wt %, and F=0.060 wt %/Pa; andd) a “weight fraction (w) of molecular weight greater than 106 g/mole, based on the total weight of polymer, and as determined by GPC(abs),” that meets the following relationship: w<I+J(I2), where I=0.080, and J=−4.00×10−3 min/dg. |
