Abstract
The invention provides an ethylene homopolymer formed from a free-radical, high pressure polymerization process in a tubular reactor system, said homopolymer comprising the following properties: (A) a density from 0.9190 to 0.9250 g/cc; (B) a hexane extractable level that is less than, or equal to, 2.6 wt %, based on the total weight of the polymer; (C) a G (at G″=500 Pa, 170C) that meets the following equation: G>D+E[log(12)], where D=150 Pa and E=−60 Pa/[log(dg/min)]; and (D) a melt index (12) from 1.0 to 20 dg/min.
