Gas phase polyethylene copolymers

An ethylene copolymer, comprising:

• about 92.5 mol % to about 97.5 mol % ethylene derived units;
• and
• about 2.5 mol % to about 7.5 mol % hexene-derived units,
• wherein the copolymer has
• a density of about 0.905 g/cm3 to about 0.911 g/cm3;
• a first Melt Index (I2) of about 0.4 to about 3.4 dg/min, as measured according to ASTM D138(190° C./2.16 kg);
• a second Melt Index (I21) of about 5 to about 60 dg/min, as measured according to ASTM D138 (190° C./21.6 kg);
• a Melt flow ratio (I21/I2) of about 16 to about 17;
• and
• a Dow Rheology Index (DRI)/Melt Index (I2) ratio (DRI/I2) of about 0.007 to about 0.060;
• wherein the copolymer is produced by
• introducing the ethylene and the 1-hexene to a single gas phase reactor at a 1-hexene/ethylene mole ratio of about 0.02 to about 0.03, as determined by measuring moles of the 1-hexene and the ethylene in a vapor overhead of the single reactor;
• and
• polymerizing the ethylene and the 1-hexene at a temperature of about 75.56° C. to about 80° C. and a pressure of from 290.0 psig to 299.7 psig.
