Title:
LOW DENSITY ETHYLENE-BASED POLYMERS WITH BROAD MOLECULAR WEIGHT DISTRIBUTIONS AND LOW EXTRACTABLES
Document Type and Number:
WIPO Patent Application WO/2013/078018
Kind Code:
A3
Abstract:
The invention provides an ethylene-based polymer comprising the following properties: a) a melt index (12) > 2.0 dg/min; b) a Mw(abs) versus 12 relationship: Mw(abs) < A + B(I2), where A = 2.40 x 105 g/mole, and B = -8.00 x 103 (g/mole)/(dg/min); and c) a G' versus 12 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 (12) > 2.0 dg/min; b) a G' versus 12 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; and d) 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 x 10-3 min/dg.
