LOW DENSITY ETHYLENE BASED POLYMERS WITH EXTRACTS AT LOWER MOLECULAR WEIGHTS

摘要

The invention provides an ethylene based polymer comprising the following properties: A) 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 < A + B(I2) where A = 0.090 and B = 4.00 x 10 3 (min/dg); B) a G value that meets the following relationship: G < C + Dlog(I2) where C = 162 Pa and D = 90.0 Pa/log(dg/min); C) a melt index (I2) from 1 to 20 dg/min; and D) chloroform extractable that has a maximum Mw(conv) of less than or equal to 4 000 g/mole.
